FAQ

Q: Who are the leading linear guide rail manufacturers?

A: Commonly compared manufacturers include THK, HIWIN, IKO, PMI, Bosch Rexroth, NSK, CPC, TBI Motion and SCHNEEBERGER. The appropriate choice depends on dimensions, load, accuracy, preload, environment and supply requirements.

Q: How do I choose a linear guide supplier?

A: Confirm that the supplier can check the complete model, rail length, carriage quantity, accuracy class, preload and documentation. Availability, lead time, quotation terms and replacement verification are also important.

Q: Are THK and HIWIN linear guides interchangeable?

A: Not automatically. Rail width alone is insufficient. Compare the series, rail profile, carriage dimensions, mounting-hole pitch, load rating, preload and accuracy class before considering replacement.

Q: Which linear guides are suitable for CNC machines and robotics?

A: CNC machines normally prioritize rigidity, preload and positioning accuracy, while robotics may prioritize compact size, low mass and smooth motion. The final model should be selected from the application requirements rather than the brand name alone.

Q: What information is needed for a linear guide quotation?

A: Send the brand, complete model number, rail length, carriage quantity, mounting dimensions, load, speed, accuracy or preload requirement and operating environment.
