Q1: What is an interchangeable linear guide?

An interchangeable linear guide uses standardized dimensions so that blocks can be exchanged on any rail of the same size and accuracy class. In most cases, you can replace only the block while keeping the existing rail, as long as the mounting dimensions and preload class match your original design.

Q2: What is a non-interchangeable (matched set) linear guide?

A non-interchangeable, or matched-set, linear guide is factory paired: each block and rail are measured and supplied as a set. They are not intended to be mixed with other rails or blocks. When this type becomes obsolete, maintenance usually requires a full set replacement, including rail and blocks, rather than changing the block alone.

Q3: How do I know whether I can replace only the block or nut?

First, confirm whether your existing system is interchangeable or non-interchangeable. Then check key dimensions: rail width, mounting hole spacing, rail height, block mounting pattern, and for ball screws, shaft diameter and lead. If the system is interchangeable and a new series shares the same mounting dimensions, you can often replace only the block or ball nut. If it is a non-interchangeable matched set that is fully obsolete, a complete replacement kit is the safer solution.

Q4: Can TranzBrillix linear guides replace HIWIN linear guides?

In many popular sizes, TranzBrillix linear guides are designed around main HIWIN mounting dimensions and can be used as HIWIN-compatible replacements. For some projects we can also evaluate mixed solutions, such as a TranzBrillix block on an existing HIWIN rail, provided that the dimensions, preload and running performance are carefully verified before use.

Q5: What if my HIWIN linear guide is non-interchangeable and discontinued?

When a non-interchangeable HIWIN model is completely discontinued, the most reliable approach is a full set replacement. As a linear guide manufacturer, TranzBrillix can engineer a complete compatible kit based on your original installation: rail length, stroke, mounting hole pattern, overall height and load requirements. The goal is to keep your machine layout as close as possible while restoring or improving accuracy and rigidity.

Q6: What information should I prepare before asking for a replacement proposal?

To speed up the engineering review, please prepare clear photos of the existing rail and block (including nameplates), basic dimensions (rail width, hole spacing, stroke and total length), and any available drawings or sketches. With this information, TranzBrillix can quickly confirm whether an interchangeable repair is possible or whether a full HIWIN-compatible replacement set is the better option.
