TranzBrillix MG micro linear guides – designed as a drop-in replacement for HIWIN MG rails and carriages, giving lab automation and IVD OEMs a qualified second source and a clear path to BOM cost reduction.

• Drop-in compatible mounting dimensions for many HIWIN MG sizes
• Factory-backed production using alloy & high-carbon chromium bearing steel (stainless options available)
• Validated under clinical analyzer duty cycles, not just catalog conditions
• Potential 20–30% savings on the linear guide BOM line for OEM manufacturers

Over the past few years, lab automation and IVD instrument OEMs have been under pressure from both sides:

• Supply chain risk: single-brand dependence on MG-type micro linear guides makes projects vulnerable to lead-time spikes and allocation.
• Cost pressure: inflation and price increases have pushed BOM costs higher while instrument selling prices are heavily constrained.
• Regulatory and reliability requirements: any alternative must pass real clinical application tests, not just look good on paper.

For many OEMs, the ideal solution is not to “throw away HIWIN", but to qualify a serious second source that:

• Fits existing designs without re-machining mounting surfaces
• Performs equivalently at the analyzer or module level
• Offers a more flexible and cost-efficient supply chain

TranzBrillix MG micro linear guides are produced in our own linear-motion factory on dedicated MG/MGN production lines. Rails and blocks are made from alloy and high-carbon chromium bearing steel, with stainless steel options available for more aggressive environments.

The series is targeted at applications such as:

• Clinical analyzers and IVD instruments
• Lab automation modules and sample handling systems
• Compact biotech and life-science automation platforms
• High-precision 3D printers and inspection equipment

The key design goal is simple: deliver a HIWIN MG-compatible micro guide that OEMs can evaluate without having to redesign their mechanical platforms.

TranzBrillix MG micro linear guides are designed to be dimensionally compatible with many commonly used HIWIN MG / MGN sizes, so your mechanical team can reuse existing rail and carriage interfaces.

Note: For a detailed 1:1 mapping between your HIWIN MG part numbers and TranzBrillix MG references, please share your BOM or part list. We will provide a specific cross-reference and drawings for engineering review.

A true HIWIN MG alternative must be validated in real duty cycles, not just on a drawing. TranzBrillix MG has been evaluated with OEM partners under conditions such as:

• Low-speed probing and sample motions using micro-stepping drives
• Start–stop indexing of carousels and trays with frequent acceleration/deceleration
• High-cycle life tests (e.g. 2 million strokes at ~0.25 m/s under representative loads)
• Noise and vibration measurement at the analyzer level
• Cleaning-agent wipe tests with alcohol-based lab cleaners

In a recent case with a U.S. clinical analyzer OEM, TranzBrillix MG was:

• Confirmed as equivalent in low-speed smoothness (no visible stick–slip)
• Verified at the system level to keep noise within the same band as the HIWIN MG baseline (around 60 dB(A) at 1 m in the OEM’s test sequences)
• Run through a 2-million-stroke accelerated life test with no abnormal wear, spalling, or jamming observed

The test plans in these projects were jointly defined by OEM engineering teams and TranzBrillix application engineers, ensuring that the results reflect real-world use rather than idealized conditions.

For OEMs that consume thousands of MG-type micro guides per year, even small unit price differences add up quickly. In the U.S. clinical analyzer case, the OEM found that:

• TranzBrillix MG delivered comparable performance to their HIWIN MG baseline
• The linear guide line item in the BOM could be reduced by about 20–30%

The budget freed from the MG rail and carriage line item was instead invested in:

• Higher-end optics and sensors
• Software, UI, and connectivity features
• Field service and market launch support

For many OEM teams, this is the real value of a validated HIWIN MG alternative: you get engineering flexibility, supply security, and cost leverage without tearing up your existing designs.

Choosing a second source is not only about price. It is about trusting that your supplier understands both linear guide manufacturing and your application.

• Own factory: TranzBrillix MG micro guides are made in our own facility, with controlled heat treatment, grinding and assembly processes.
• Materials: rails and blocks use alloy and high-carbon chromium bearing steel; stainless steel options are available for corrosion-sensitive environments.
• Inspection & QC: dimensional checks, preload control, smoothness checks and visual inspection before shipment.
• Application engineering: support for cross-referencing HIWIN MG part numbers, basic life estimates, and test plan suggestions for your own validation.

The objective is not to replace your internal engineering work, but to give your team a serious, technically grounded partner on the linear guide side.

If you are currently using HIWIN MG / MGN rails and carriages in a lab automation, IVD, or biotech instrument project, you do not have to redesign your machine to explore alternatives.

To start a TranzBrillix MG evaluation, you can:

1. Send us your current HIWIN MG part numbers and annual quantities
2. Share basic duty cycle info (speed, stroke, load, environment)
3. Tell us your priorities (cost reduction, second source, regional stocking, etc.)

We will respond with:

• A TranzBrillix MG cross-reference list for your part numbers
• Outline of a suggested validation plan based on your application
• Initial commercial terms for prototype and pilot runs
