• Customization scope: non-standard bolt pitch, special slider shapes, special flanges, special keyways and other structures.
• Drawing requirements: material, heat-treatment requirements, tolerances on critical dimensions, surface treatment and quantity must be clearly marked.
• Co-design: if the information is incomplete, our engineers can help refine the design before final confirmation for production.

Guides can be precisely cut to length with the following options:

• Cutting mode: (1) single piece to a specific length (e.g. 750 mm, 820 mm); (2) multiple sections for butt-joint usage (e.g. 2 * 1200 mm).
• Edge finishing: all cut ends are chamfered and deburred to avoid damage to carriages and seals.
• Positioning marks: mounting reference surfaces are re-marked after cutting to keep installation accuracy.
• Engineering advice: for high-precision or long-travel applications, we can provide paired processing or segmented butt-joint solutions.

Yes, we offer fully customized end machining:

• Machining range: shaft diameter, shoulders, snap-ring grooves, keyways and other end features according to your drawings.
• Matching service: keyways, keys, lock-nut threads and circlip grooves can be machined at the same time to fit support units directly.
• Selection convenience: standard end machining reference drawings are available for direct selection or minor modification.
• Accuracy assurance: dynamic balance is checked after machining for stable high-speed operation.

Yes, we support non-standard designs in the following scope:

• Housing design: customized housings according to bolt pattern and available installation space.
• Material options: aluminum alloy, carbon steel, ductile cast iron and others.
• Mounting styles: bottom mounting, side mounting, clamp-plate mounting and more.
• Batch notes: for large volumes, tooling cost and lead time need to be confirmed in advance.

We can support multi-dimensional selection based on:

• Load: calculate equivalent load and keep a safety factor of 1.5–2.0.
• Mounting: choose flange or block-type carriages, open or closed housings, etc.
• Space: determine guide/screw size and installation height according to your layout.
• Accuracy: select standard or high-precision products based on speed and accuracy requirements.
• Engineering support: you can provide equipment photos or old part numbers for our engineers to cross-check.

Our typical accuracy indicators (adjustable by series and grade) are:

• Straightness: up to ±0.01 mm/m for precision-grade products.
• End accuracy: cut end squareness meets the requirement for smooth carriage travel.
• Surface quality: ground surfaces can reach Ra 0.2–0.4 µm.
• Inspection support: straightness and parallelism reports can be provided upon request.

Using CNC cutting and finishing, we control:

• Standard tolerance: ±0.5 mm.
• Tight tolerance: up to ±0.2 mm or better when specified before ordering.
• Batch control: for multiple pieces in one batch, same-length guides can be paired within ≤0.2 mm difference.

In line with relevant GB/T standards, our key tolerances are:

• Shaft diameter: normally h7, and up to h6 for precision requirements.
• Shoulder run-out: typically controlled within 0.01–0.02 mm (depending on size and grade).
• End squareness: meets the requirement of support units to ensure axial run-out is within spec.
• Special cases: higher precision can be discussed in detail based on drawings.

We recommend surface treatments based on material and application:

• Carbon steel: ground base + anti-rust oil, blackening, black chrome, nickel plating, etc.
• Stainless steel: ground base + anti-rust oil and passivation.
• Aluminum housings: natural or black anodizing.
• Selection factors: corrosion resistance, appearance, cost and lead time are considered together.

Yes, we can supply associated machining services:

• Machining scope: steel or aluminum base plates and brackets according to order requirements.
• Drawing requirement: complete machining drawings and assembly notes are needed.
• Delivery: matched parts can be packed and shipped together with guides and screws to reduce your assembly work.

We use in-house pairing and running-in processes:

• Standard delivery: guides and the corresponding number of carriages are shipped as complete sets.
• Precision assurance: multiple carriages on one rail are matched by smoothness and preload value.
• Spare carriages: if you order spare carriages, pairing codes and instructions will be clearly marked on the packaging.

To ensure running accuracy and service life:

• Reference surface: mounting surfaces should be milled or ground to ensure flatness.
• Installation order: fix the reference-side rail first, then adjust the other rail for parallelism.
• Fastening: tighten screws gradually in a criss-cross pattern to avoid rail distortion.
• Verification: manually move the carriage along full stroke to check for any tight or binding points.

We do not recommend removing carriages from rails by yourself:

• Risk warning: improper removal may cause balls to fall out, affecting accuracy and service life.
• Correct method: if removal is necessary, use a special mounting/dismounting rail or dummy rail.
• After damage: if balls are lost or misaligned, the assembly should be returned for reassembly and calibration.

Follow these guidelines for stable transmission:

• Fit: end shaft dimensions must match the bore of support units and bearings accurately.
• Assembly order: insert the screw into the nut housing first, then assemble with the support unit to avoid ball loss.
• Preload: adjust axial clearance and preload properly to avoid overheating (too tight) or vibration (too loose).
• Safety: plan rotation direction and limit positions in advance to prevent overtravel or collision.

Main installation requirements:

• Housing fit: housing bore and bearing OD are usually H7/h6 interference or transition fits; use proper tools for pressing.
• Shaft fit: shaft and linear bearing are typically G6/h6 fits to ensure sliding accuracy.
• Open type: open bearings must be clamped together with shafts or guides to avoid over-deformation.
• Shaft surface: shafts should be ground with no burrs, dents or other defects.

Yes, pre-lubrication is done at the factory:

• Standard configuration: guide carriages, ball screw nuts and linear bearings are pre-filled with general-purpose lithium grease or dedicated guide grease.
• Customized grease: we can fill specific grease brands/types according to your requirements.
• Special cases: for long-distance sea shipment or long-term storage, extra anti-rust grease will be applied.

We recommend the following steps:

• Incoming inspection: check appearance, model and quantity against the packing list.
• Cleaning: gently wipe away excess anti-rust oil with a clean cloth. Do not use strong solvents for aggressive cleaning.
