A linear guideway that looks right can still be wrong for the machine. The series, size, block style, rail length and mounting details decide whether the replacement fits.
Sardar Mill Store is your No. 1 choice for Hiwin guideway enquiries in Delhi when fitment and straight answers matter.
What to send with a Hiwin enquiry
- The full code printed on the block or rail, including suffixes if visible.
- Rail size and length, block quantity, and whether the rail needs machining.
- A clear photograph or technical drawing showing the mounting arrangement.
- Machine model, application and whether you are replacing or building new.

Why similar-looking guideways are not interchangeable
Block geometry, mounting-hole spacing, rail profile, load rating and preload can differ between product families. A replacement should be checked against the existing assembly or the machine's design requirements.
For a complete motion requirement, ask about the related ball screw, support unit, linear bearing or shaft as well. A useful enquiry describes the assembly, not only one component.

Common buyer questions
Can I enquire without the Hiwin part number?
Yes. Share rail dimensions, block photographs, the machine model and any drawing you have. The more fitment details you provide, the easier it is to narrow the enquiry.
Do rail and block details both matter?
Yes. They work as an assembly, and seemingly small differences in profile or mounting pattern can affect fit. Confirm the exact combination before ordering.
Can Sardar Mill Store help buyers outside Delhi?
Yes. Share the destination with your part details so the team can discuss a Pan-India courier option after confirming the requirement.
