Yes, in many cases we can.
Many engineers use McMaster-Carr and MISUMI as their design libraries because CAD models are easy to download. We don’t sell those original brands, but we can often provide dimensionally compatible, cost-effective alternatives.
However, it is very important to distinguish between:
Standard parts that can be direct drop-in replacements, and
Assemblies that must be replaced as a complete set (rail + block).
For components that follow common ISO/JIS or industry standards, we can usually supply dimensionally equivalent parts:
Linear shafts and shaft supports
Metric and inch linear shafts
Shaft supports such as SK / SHF / T-shaped supports
Linear ball bearings
Standard LM / LME series
Flanged types LMF / LMK
Housed units SC / SCS / SBR blocks
Ball screw assemblies
Standard metric ball screws (e.g. SFU series)
With standard end machining for BK/BF, FK/FF, EK/EF supports
In many cases, we can match the diameter, lead, support type and nut style to drop into your design
For these standardized parts, a McMaster or MISUMI part number is often enough to create a 1:1 dimensional alternative. Performance (load rating, life) may differ slightly by brand, but fit and function can usually be kept the same.
For linear guides (rail + block) and some proprietary assemblies, “compatible” does not mean you can mix components:
We can provide dimensionally interchangeable linear guide sets
Same rail width, height and mounting hole pattern
Same overall block height and reference dimensions
Suitable to replace many MISUMI / McMaster branded guides as a set
⚠ Critical Warning: Do NOT mix brands on the same rail
Even if two brands use the same nominal size (e.g. “HGH25”), the ball groove geometry, contact angle and tolerances are different.
You must not buy only our block and mount it on an existing MISUMI, McMaster or other-brand rail (or the opposite).
Mixing different brands’ blocks and rails can cause:
Very rough motion or jamming
Abnormal wear and loss of accuracy
In extreme cases, ball cage failure
Choosing a linear bearing is not only about shaft diameter. You must check:
Shaft hardness and tolerance (basic conditions)
Bearing format – raw LM vs housed SC/SBR units
Open vs closed type – floating shaft vs supported rail
Standard vs long type – stability and moment rigidity
Hardness
LM linear ball bearings are designed to run on hardened shafts (typically HRC 60+).
If you use soft mild steel or soft 304 stainless with steel balls, the balls will quickly dig grooves into the shaft and destroy accuracy.
Tolerance
The ID of LM bearings is made to fit precision ground shafts with g6 or h6 tolerance.
If the shaft is too small (e.g. generic cold-drawn rod with big minus tolerance or poor roundness), the bearing will feel loose and wobble.
If the shaft is too large (e.g. k6 or positive tolerance chrome bar), the bearing may jam, run rough or even break the ball cage.
The main differences are surface hardness, corrosion resistance and which bearing types they can safely work with.
1. Hardened carbon steel shafts (45# / SUJ2 / CF53)
Typical material and treatment
Medium/high carbon steel or bearing steel (45#, SUJ2, CF53, etc.)
Usually induction hardened on the surface to about HRC 60–64
For industrial use, they are almost always hard chrome plated (hard chrome shaft), so they are not “bare raw steel".
Best suited for
About 90% of industrial automation: CNC machines, linear modules, 3D printers, packaging, handling, etc.
Any application using standard linear ball bearings (LM, LME series).
Bearing compatibility
Hardened, chrome-plated surface with HRC 60+ is a perfect match for steel linear ball bearings.
Ball hardness and shaft hardness are similar, so the surface can withstand the point contact stress without grooving.
Corrosion behaviour
The hard chrome layer provides basic corrosion protection in indoor and normal workshop environments.
In outdoor, splash water or aggressive environments they can still rust and may need extra protection (grease, wipers, boots).
2. 304 stainless steel shafts (soft stainless)
Material characteristics
Austenitic stainless steel (304) cannot be through-hardened by heat treatment.
Typical surface hardness is only around HRC 20–25, much softer than bearing steel.
Best suited for
Food, beverage and pharmaceutical machinery
Medical and semiconductor equipment
Wet, hygienic or chemically aggressive environments where corrosion resistance is critical and loads are light to medium.
⚠ Critical warning: do NOT pair 304 shafts with standard steel linear ball bearings long term
Steel balls in LM-type bearings are typically around HRC 60.
When hard balls roll on a soft HRC 20–25 shaft under load, the contact stress is very high →
The balls will quickly indent and groove the shaft surface (Brinelling / grooving).
Precision, smoothness and shaft life drop dramatically.
304 stainless shafts are not meant to be used as “soft rails" for steel ball bearings in heavy or continuous-duty applications.
Correct pairings for 304 shafts
Polymer bearings / plastic bushings (e.g. IGUS-type)
Bronze / brass plain bushings
These materials are softer than the shaft and distribute load better, so they will not destroy the 304 surface and can work in wet, washdown or no-lubrication conditions.
3. Need both hardness and corrosion resistance?
If you need:
High load capacity with steel linear ball bearings, and
Better corrosion resistance than chrome-plated carbon steel,
then consider:
440C martensitic stainless steel shafts
Can be heat-treated to HRC ~58+
Offer a compromise between stainless behaviour and high hardness
More expensive than 45#/SUJ2 shafts and usually treated as a premium option.
Practical summary
Use hardened 45#/SUJ2/CF53 chrome-plated shafts for most industrial axes with LM/LME linear ball bearings.
Use 304 stainless shafts mainly when corrosion resistance and hygiene are more important than high load and long-life with ball bearings, and pair them with polymer or bronze bushings, not standard steel linear ball bearings.
If you need a fully stainless system with ball bearings and high load, look for 440C stainless shafts and matching stainless linear bearings.
Yes. We can machine additional mounting holes, special pitches and different end hole patterns on the rail according to your 2D drawing, as long as the minimum edge distance and hole spacing are respected for strength. For critical axes we recommend you send us the complete rail and base drawing so we can double-check the layout.
The critical speed of a ball screw is the rotational speed at which the screw starts to resonate and “whip" like a jump rope. It depends mainly on the screw diameter, unsupported length, and end support condition.
You can evaluate it in three steps:
As a practical example, take a common SFU1605 screw with standard fixed–supported (BK12/BF12) mounts:
Up to ~1000 mm: Usually safe to run in the 2000–3000 rpm range.
1000–1500 mm: Becomes a warning zone. It is safer to limit the top speed to 800–1000 rpm.
Longer than 1500 mm: The risk of whipping increases significantly. You must calculate the specific limit or upgrade the design.
The critical speed is inversely proportional to the square of the unsupported length.
Physics: If you double the length, the allowable speed drops to one quarter.
This is why long, thin screws are so difficult to spin fast. Even a small reduction in unsupported length (minimizing overhang) can produce a big improvement in permitted RPM.
Option A – Larger Diameter (Most Direct):
Stiffness grows with diameter. Upgrading from 16 mm to 20 mm or 25 mm significantly increases stiffness, allowing higher speeds for the same length.
Option B – Improve End Supports (Most Economical):
Standard mounts are usually Fixed–Supported. If you upgrade to Fixed–Fixed (fixing both ends with BK units and applying tension/stretching to the screw), the critical speed can increase by ~50%.
Note: This requires precise mounting alignment.
Option C – Rotating Nut (Ultimate Solution for Long Axes):
Once travel exceeds 2–3 meters, spinning the screw becomes impractical.
The solution is to keep the screw stationary and rotate the nut (using a rotating nut assembly). Since the screw doesn't spin, there is no whipping, allowing for high speeds over very long distances.
The lead of a ball screw defines how far the nut travels per one revolution of the screw. It affects:
Linear speed (mm/rev)
Thrust and effective “mechanical reduction”
Positioning resolution
Back-driving / self-locking behaviour on Z-axes
How your motor torque curve is used
You can think about it in four steps:
Smaller lead (e.g. 2–5 mm):
1 rev = fewer millimetres of travel
Acts like a higher gear reduction
More thrust for the same motor torque
Finer positioning resolution
But for the same motor RPM, linear speed is lower
Larger lead (e.g. 10–20 mm):
1 rev = more millimetres of travel
Acts like a lower gear reduction
Less thrust and lower resolution for the same motor
But higher maximum linear speed at the same RPM
This is the “textbook” mechanical view. In real machines, two more things matter a lot: self-locking on vertical axes and the motor torque curve.
Ball screws are generally efficient and can be back-driven, but lead still changes how easily gravity can move the axis:
Small leads (e.g. 2–5 mm):
Smaller helix angle, more friction per unit of vertical force
With the help of nut friction and motor holding torque, a light or medium Z-axis often behaves almost self-locking – it is hard to push down by hand and less likely to drop quickly when power is off.
Large leads (e.g. 10–20 mm):
Larger helix angle, easier to back-drive
A heavy spindle or Z-axis can slide down under its own weight as soon as power is removed if there is no brake or counterbalance.
Practical guidance:
For vertical Z-axes, especially on machines without brake motors, it is safer to use a smaller lead (4–5 mm) so the axis is less willing to fall when power is lost.
If you choose a large-lead screw on a heavy Z-axis, you should plan for a brake motor, counterweight or gas spring, otherwise a power cut can drop the head onto the workpiece or table.
On paper, a smaller lead always gives more thrust for a given motor torque. But in practice:
Stepper motors lose torque rapidly at high RPM
At 1500–2000 rpm, a typical stepper has much less torque than at 300–600 rpm
To reach a given linear speed with a small lead, the motor must spin much faster:
Example:
4 mm lead at 2000 rpm → 8 m/min
10 mm lead at 800 rpm → 8 m/min
At 2000 rpm the motor torque may be very low, while at 800 rpm it is still in a stronger part of the torque curve.
The result is that for high-speed axes, a larger lead with lower motor RPM can actually deliver more usable thrust and better reliability than a small lead forced to spin very fast.
This is especially true for:
Long axes where screw critical speed limits RPM
Systems without high-voltage or high-current drivers to support very high motor speeds
Precision + high thrust, moderate speed:
Small lead (e.g. 2–5 mm) is ideal when you want high resolution and don’t need extreme rapid speeds.
Good for many Z-axes, precision positioning and heavier but slower axes.
General CNC X/Y axis (desktop to mid-size):
Leads around 5–10 mm are commonly used.
5 mm gives a nice balance for many SFU1605 axes.
10 mm can be good for light but fast gantries when paired with a strong motor.
Vertical Z-axis without brake motor:
Prefer smaller leads like 2–5 mm to reduce back-driving.
If using 10–20 mm lead on a heavy head, plan for a brake or counterbalance.
In all cases, try to design so that the motor runs in the “plateau” region of its torque curve (not at the extreme high-RPM tail), and choose the lead accordingly instead of only looking at a simple “speed vs thrust” formula.
SFU1204, SFU1605 and SFU2005 are common metric ball screws, but the choice is not only about “how big the machine is". You must consider diameter vs length (critical speed), lead and end support, and for larger diameters also rotational inertia.
The thinner and longer a screw is, the easier it will “whip" at high speed (like a jump rope). Critical speed depends on diameter, unsupported length and support type, but some practical rules of thumb (for rotating screws) are:
SFU1204 (12 mm diameter)
Good for shorter strokes, e.g. up to about 400–600 mm at medium speed.
When you approach 600–700 mm or more and want high RPM (around 1000 rpm), the risk of resonance and whipping increases sharply unless you keep speed low or improve supports.
SFU1605 (16 mm diameter)
Noticeably higher stiffness than 1204.
Commonly used for strokes around 400–1000/1200 mm at medium-to-high speeds with standard support (BK12/BF12).
SFU2005 (20 mm diameter)
Chosen not only for load, but also to handle longer spans and reduce deflection and whipping.
For axes longer than ~1000–1200 mm, or heavier gantries, SFU2005 often becomes a safer choice if you want to keep speed and vibration under control.
Even on a light machine, a 1 m long rotating SFU1204 at high speed can whip badly. If you need long travel at high speed, move up in diameter or reduce rotational speed.
Lead determines how far the nut travels per motor revolution:
SFU1204 – 4 mm lead
1 motor rev → 4 mm travel.
Acts like built-in reduction:
Higher thrust and finer resolution for the same motor torque and microstepping.
But lower linear speed at the same RPM.
SFU1605 / SFU2005 – 5 mm lead
1 rev → 5 mm travel.
An “industry standard" lead, easy for step/mm calculations.
Allows higher linear speed at the same motor RPM, with slightly lower thrust and resolution than a 4 mm lead.
Each screw size is usually paired with matching support units:
SFU1204 → BK10 / BF10
Smaller bearings, suitable for lighter loads and shorter screws.
For strong cutting or long travel, the BK10 fixed bearing can become a stiffness bottleneck before the screw itself.
SFU1605 → BK12 / BF12
Very common industrial combination with larger fixed bearings and better rigidity.
A solid choice for many desktop and 6040-style CNC machines.
SFU2005 → BK15 / BF15 or similar
Even larger bearings and housing, designed to support higher loads and longer screws.
Screw inertia grows roughly with the diameter to the fourth power. A 20 mm screw can have several times the rotational inertia of a 16 mm screw of similar length. This means:
It needs more motor torque to accelerate and decelerate.
If you pair SFU2005 with a small stepper (for example a modest NEMA23) and try aggressive acceleration, you may see stalling or missed steps.
Whenever you choose SFU2005 (or larger), plan on using a stronger motor and drive (larger NEMA frame or servo), or use more conservative acceleration profiles.
Putting it together:
Choose SFU1204 when:
Stroke is relatively short (around ≤ 400–600 mm),
The axis is light and you value fine resolution and higher thrust at modest speeds,
You are okay with BK10/BF10-level support capacity.
Choose SFU1605 when:
You have a desktop CNC or 6040-class machine with travel around 400–1000 mm,
You want a good balance of stiffness, speed, cost and reasonable inertia,
You prefer robust, standard BK12/BF12 supports.
This is the best starting point for most DIY and light industrial X/Y axes.
Choose SFU2005 when:
Travel is ≥ 1000–1200 mm or the moving mass is clearly heavier,
You are concerned about deflection and whipping at your target speeds,
You are ready to design around bigger supports and higher motor torque to handle the increased rotational inertia.
For any important axis, it is still recommended to check the calculated critical speed and bearing load ratings instead of relying only on rules of thumb.
C7, C5 and C3 are accuracy grades that define the lead error of a ball screw over a reference length. They do not directly define backlash. You can think of them like this:
Process: Usually cold-rolled (rolled ball screw), lowest cost.
Lead accuracy: Typical tolerance is around ±0.05 mm per 300 mm travel (exact value depends on the standard and manufacturer).
Best suited for:
3D printers and hobby CNC
Wood routers and basic engraving machines
Handling modules, packaging machines and general automation where ±0.1–0.2 mm over the stroke is acceptable
Backlash note: Most C7 screws are supplied with a standard single nut that has some clearance.
If you require minimal backlash, you must choose a preloaded nut (oversized balls) or a double-nut design. Upgrading from C7 to C5 alone does not magically remove backlash.
Process: Traditionally, C5 is ground and significantly more expensive than C7 (often 3–5*).
Lead accuracy: Around ±0.018 mm per 300 mm travel (depending on standard/manufacturer).
Best suited for:
Industrial CNC milling and turning machines
Precision positioning axes in automation
Applications that need tighter dimensional control over long strokes
Benefits:
Better lead accuracy and repeatability
Smoother running and lower noise compared to many rolled C7 products
Middle option: There are now C5 rolled ball screws on the market which offer better accuracy than standard C7 with a lower price than fully ground C5. For many machines, this is a good compromise between cost and performance.
Process: High-end ground ball screws, often with strict temperature control during manufacturing.
Lead accuracy: Around ±0.008 mm per 300 mm.
Best suited for:
Jig grinders and high precision grinding machines
Semiconductor equipment
Coordinate measuring machines (CMM) and ultra-precision positioning systems
Accuracy grade ≠ zero backlash
C5 tells you the screw “walks the right distance" (lead accuracy).
It does not guarantee that there is no axial play when you reverse direction.
If you care about lost motion / backlash, you must specify a preloaded nut or double-nut solution. This is often more important for feel and positioning at reversal than the difference between C7 and C5 grades.
Long travel and cumulative error
The often-quoted accuracy values (e.g. per 300 mm) are per segment, not for the entire axis.
On a 1 m or longer axis, C7 lead error can accumulate to several tenths of a millimeter.
If your axis is long and you need parts to fit accurately over that whole length, you should seriously consider C5 (or at least a higher-accuracy rolled option) even if you don’t need the absolute smoothness of ground C5.
How to choose in practice
C7 rolled – when budget is limited and your acceptable error is in the ±0.1–0.2 mm range over the stroke. Combine it with a preloaded nut if you want less backlash.
C5 (ground or high-accuracy rolled) – when you build serious CNC equipment or long-travel axes that need better dimensional accuracy and smoother motion.
C3 ground – only when you clearly need high-end precision and your machine structure, feedback system and temperature control can actually take advantage of that grade.
Narrow MGN guides (for example MGN9H, MGN12H) and wide MGW guides (such as MGW9, MGW12) are both miniature profile rails, but they optimize different directions of moment load:
MGN-H (long block)
The “H" long block version mainly increases the pitching and yawing moment capacity (Mp and My):
Pitching: front–back nose diving of a cantilever (up/down at the end)
Yawing: twisting around a vertical axis
A longer block gives a longer distance between the rolling elements along the rail, which helps when the load tries to tip the carriage forward or backward along the travel direction.
MGW (wide block and rail)
The wide MGW series mainly increases the rolling moment capacity (Mr):
Rolling: side-to-side tilting of a bed or arm (left/right roll)
The wider base and block footprint make MGW much stronger against a load that tries to flip the carriage sideways, especially when you only have one rail supporting a bed or arm.
In practice:
If your main concern is a cantilever arm or tool head that “noses down" or “twists" along the travel direction, a long MGN-H block can already provide very good support.
If your main concern is a single-rail bed that wants to “roll" left/right, a wide MGW rail is usually the safer choice.
For many 3D printers, designers use MGN12H on X/Y carriages to control pitching and yawing, and choose MGW9/MGW12 under a single-rail bed where rolling is critical. The final decision should still be checked against the catalog moment ratings (Mp, My, Mr) for your load direction and mounting.
Roller type guides like RG or QR use cylindrical rollers instead of balls. Compared with ball-type HG guides of the same size, they offer:
Much higher rigidity and load ratings (especially for moment loads)
Better resistance to vibration and deformation in heavy cutting
They are a strong choice for very heavy cutting, high column machines, boring mills and axes where even small deflection is not acceptable.
However, there are important trade-offs you must consider:
Maximum speed and heat
Roller guides have line contact and higher friction than ball guides. This means:
Lower maximum recommended speed
More heat generation at high speeds
On very fast automation axes (high m/min), using roller guides without checking the catalog limits can cause overheating and grease breakdown.
Installation surface flatness
Because roller guides have very high rigidity and very little self-alignment capability, they are more sensitive to base flatness and parallelism.
If the mounting surfaces are not machined accurately, the preload can become too high locally.
The axis may feel very heavy, wear quickly or even bind.
With HG ball guides, minor errors are sometimes absorbed; with RG/QR you must have a better-machined base.
Required driving torque
Higher friction also means higher motor torque is needed:
Starting torque and running torque are both higher than with HG
If you upgrade from HG to RG/QR without adjusting the motor and drive, you may see overload alarms or following error.
In summary, roller guides are recommended only when you clearly need very high rigidity and load capacity, and your machine can support higher base machining accuracy, lower speed or higher motor torque. For many axes, a well-selected HG series is still the more balanced and economical choice.
HG is a heavy-duty, high-profile series with high rigidity, mainly used on CNC machine tools and rigid gantry axes. EG is a low-profile, lighter series that keeps reasonable rigidity but reduces overall height and weight, making it better for automation modules, pick-and-place units and compact machines.
In addition to profile and rigidity, the rail width and mounting hole pitch of HG and EG are not always the same, so they are usually not drop-in interchangeable. If you plan to switch from HG to EG or vice versa on an existing machine, you must check the rail width, hole spacing and counterbore dimensions carefully against your base.
Although EG is overall lower in rigidity than HG in pure vertical load, some EG variants have relatively wide rails and blocks, so their moment load ratings around roll/pitch/yaw are still quite good. For axes where overturning moment is more critical than extreme vertical rigidity, a properly sized EG guide can still be a very practical choice.
FAQ ini dirancang untuk pengguna yang mencari produsen pemandu linier, perlu memperbaiki mesin lama, atau ingin mengganti pemandu linier HIWIN usang dengan solusi TranzBrillix yang kompatibel.
Q1: Apa itu pemandu linier yang dapat dipertukarkan?
Pemandu linier yang dapat dipertukarkan menggunakan dimensi standar sehingga blok dapat ditukar pada rel berukuran dan kelas akurasi yang sama. Dalam banyak kasus, Anda hanya dapat mengganti blok sambil mempertahankan rel yang ada, selama dimensi pemasangan dan kelas preload sesuai dengan desain asli Anda.
Q2: Apa itu pemandu linier yang tidak dapat dipertukarkan (set yang cocok)?
Pemandu linier yang tidak dapat dipertukarkan, atau set yang cocok, dipasangkan di pabrik: setiap blok dan rel diukur dan dipasok sebagai satu set. Mereka tidak dimaksudkan untuk dicampur dengan rel atau blok lain. Ketika jenis ini menjadi usang, perawatan biasanya memerlukan penggantian set lengkap, termasuk rel dan blok, daripada hanya mengganti blok saja.
Q3: Bagaimana saya tahu apakah saya hanya dapat mengganti blok atau mur?
Pertama, konfirmasikan apakah sistem Anda yang ada dapat dipertukarkan atau tidak dapat dipertukarkan. Kemudian periksa dimensi utama: lebar rel, jarak lubang pemasangan, tinggi rel, pola pemasangan blok, dan untuk sekrup bola, diameter poros dan timah. Jika sistem dapat dipertukarkan dan seri baru berbagi dimensi pemasangan yang sama, Anda sering kali hanya dapat mengganti blok atau mur bola. Jika itu adalah set yang cocok yang tidak dapat dipertukarkan yang sepenuhnya usang, kit pengganti lengkap adalah solusi yang lebih aman.
Q4: Bisakah pemandu linier TranzBrillix menggantikan pemandu linier HIWIN?
Dalam banyak ukuran populer, pemandu linier TranzBrillix dirancang di sekitar dimensi pemasangan HIWIN utama dan dapat digunakan sebagai pengganti yang kompatibel dengan HIWIN. Untuk beberapa proyek, kami juga dapat mengevaluasi solusi campuran, seperti blok TranzBrillix pada rel HIWIN yang ada, asalkan dimensi, preload, dan kinerja berjalan diverifikasi dengan cermat sebelum digunakan.
Q5: Bagaimana jika pemandu linier HIWIN saya tidak dapat dipertukarkan dan dihentikan?
Ketika model HIWIN yang tidak dapat dipertukarkan benar-benar dihentikan, pendekatan yang paling andal adalah penggantian set lengkap. Sebagai produsen pemandu linier, TranzBrillix dapat merekayasa kit kompatibel lengkap berdasarkan instalasi asli Anda: panjang rel, langkah, pola lubang pemasangan, tinggi keseluruhan, dan persyaratan beban. Tujuannya adalah untuk menjaga tata letak mesin Anda sedekat mungkin sambil memulihkan atau meningkatkan akurasi dan kekakuan.
Q6: Informasi apa yang harus saya siapkan sebelum meminta proposal penggantian?
Untuk mempercepat peninjauan teknik, harap siapkan foto-foto jelas dari rel dan blok yang ada (termasuk pelat nama), dimensi dasar (lebar rel, jarak lubang, langkah, dan panjang total), dan gambar atau sketsa apa pun yang tersedia. Dengan informasi ini, TranzBrillix dapat dengan cepat mengonfirmasi apakah perbaikan yang dapat dipertukarkan dimungkinkan atau apakah set pengganti yang kompatibel dengan HIWIN lengkap adalah pilihan yang lebih baik.
Ketika pelanggan membeli pemandu linier miniatur (seperti seri MGN) untuk pertama kalinya, salah satu kekhawatiran yang paling umum adalah: “Blok terasa longgar pada rel, apakah pemandunya di luar toleransi?”
Dalam banyak kasus, perasaan ini berasal dari cara pemandu diperiksa, bukan dari masalah kualitas yang sebenarnya. Artikel ini menjelaskan apa arti dari “preload yang sangat ringan”, mengapa Anda masih dapat merasakan sedikit gerakan, dan kapan Anda harus mempertimbangkan tingkat preload yang berbeda.
Pesan yang sering diterima dari pengguna akhir terlihat seperti ini:
Umpan balik ini sering muncul setelah pelanggan menerima pemandu miniatur seperti MGN12H1R300Z0C dan mengujinya dengan tangan, sebelum dipasang pada mesin.
Ambil model MGN12H1R300Z0C sebagai contoh. Ini dapat diuraikan sebagai berikut:
Kesalahpahaman yang umum adalah: “Z0 berarti itu adalah tipe longgar, tipe celah, itulah sebabnya terasa goyah.”
Kenyataannya adalah sebaliknya: Z0 adalah tingkat preload yang sangat ringan, dirancang agar mendekati tanpa celah sambil tetap menjaga gesekan tetap rendah dan pemasangan lebih mudah daripada tipe preload berat.
Jika blok digerakkan dengan tangan dalam kondisi bebas (rel tidak dipasang, tidak ada meja yang terpasang), beberapa gerakan biasanya dapat dirasakan bahkan dengan preload yang sangat ringan.
Dalam banyak kasus, pengguna:
Gerakan yang diamati di sini terutama adalah:
Secara visual, itu bisa terlihat seperti “gap”, tetapi dalam banyak kasus itu hanyalah gerakan elastis yang dikalikan dengan efek tuas, bukan celah bebas yang besar.
Tujuan dari tingkat preload Z0 adalah untuk:
Oleh karena itu, tidak akan pernah terasa “keras dan terkunci” seperti pemandu yang di-preload berat. Jika seseorang mengharapkan sama sekali tidak ada gerakan yang terlihat ke segala arah, bahkan gerakan elastis kecil dapat dinilai sebagai cacat, meskipun itu normal untuk Z0.
Meskipun beberapa gerakan dengan tangan adalah normal untuk preload yang sangat ringan, ada kasus di mana pemeriksaan lebih lanjut diperlukan:
Beberapa aplikasi memerlukan blok yang terasa benar-benar ketat, tanpa celah yang terlihat ke segala arah saat dipasang. Dalam kasus seperti itu, tingkat preload yang lebih tinggi, seperti preload Z1, dapat dipertimbangkan.
Dibandingkan dengan Z0, pemandu yang di-preload Z1 akan:
Namun, ini datang dengan persyaratan penting: dasar pemasangan harus dikerjakan dengan sangat rata dan sejajar. Dengan preload yang lebih tinggi:
Singkatnya:
Untuk mengevaluasi apakah gerakan yang diamati normal atau tidak, pemandu harus selalu diperiksa dalam kondisi yang mendekati penggunaan sebenarnya. Prosedur sederhana adalah:
Belum tentu. Pertama periksa model dan kode preload. Untuk tipe dengan preload yang sangat ringan Z0, blok dirancang agar hampir tanpa celah, tetapi beberapa gerakan elastis masih dapat dirasakan ketika rel tidak dipasang dan blok digoyangkan dengan tangan. Ini normal untuk Z0. Selalu uji lagi setelah rel dipasang pada dasar yang rata dan blok terhubung ke meja. Jika masih ada celah bebas yang jelas, berikan data video dan pengukuran untuk evaluasi lebih lanjut.
Ya. Tingkat preload yang lebih tinggi seperti preload Z1 dapat memberikan kekakuan yang lebih tinggi dan perasaan yang sangat dekat dengan tanpa celah saat dipasang dengan benar. Namun, ini memerlukan permukaan pemasangan yang sangat rata dan akurat. Jika dasar tidak dikerjakan dengan baik, preload yang lebih tinggi dapat menyebabkan pengikatan, kebisingan, atau keausan yang dipercepat.
Anda dapat menambahkan kode preload (misalnya, Z0 atau Z1) di akhir model, atau nyatakan dengan jelas dalam pertanyaan Anda bahwa Anda memerlukan preload yang sangat ringan atau preload yang lebih tinggi, mendekati tanpa celah. Berdasarkan aplikasi dan kondisi pemasangan Anda, pemasok kemudian dapat merekomendasikan preload dan tingkat akurasi yang sesuai untuk pemandu linier miniatur Anda.
