Can I replace only the linear guide block?
Begin by identifying the existing assembly. A carriage or runner block moves along a profiled rail, but a replacement must match the applicable manufacturer requirements. A matching nominal size does not establish compatibility. Send the existing block and rail references together and state clearly whether the enquiry is for the block only or a complete assembly.
Record the make and complete markings
Photograph every readable marking on the carriage, rail and packaging. For a THK LM guide block or HIWIN linear guideway, retain all letters and suffixes. If the label is damaged, share the machine parts list or original purchase reference. Do not guess missing characters from a visually similar online photograph.
Which linear guide dimensions should I provide?
Alongside the markings, record rail width, block width and length, mounting-hole layout and assembled height where available. For a replacement rail, include total length and the end-hole positions. Use a drawing with units and identify how each dimension was measured. Dimensions assist identification; they do not independently confirm the required preload, accuracy or load capacity.
Do THK and HIWIN blocks fit the same rail?
Do not assume a THK block will run on a HIWIN rail, or that two blocks within one brand are interchangeable. The series, raceway geometry, block form and manufacturer interchangeability conditions matter. Ask for confirmation against the exact references before ordering. An equivalent-looking assembly may require a separately checked engineering change.
When the marking or specification is missing
State what is unknown. Share clear photographs of the complete assembly and fixing arrangement, plus the machine make and parts drawing if available. A photograph cannot confirm internal condition or suitability. If the rail is visibly damaged, report that with the replacement enquiry rather than assuming a new block alone will resolve the problem.
