Does SA fit in place of CA?
Not automatically. Within each size above, the SA and CA blocks share the listed height, width and rail width, but the CA block is longer and has a different published load rating. Mounting details and the machine's original specification must also be checked. A size number such as “20” does not establish interchangeability with another HIWIN family.
HIWIN also lists EGW flange-block variants. Their dimensions are not represented by this EGH square-block table. For other rail families, compare our HG ball guideway, MG miniature guideway and RG roller guideway references.
What should I send for a HIWIN EG quote?
- Full block designation, including SA or CA and any suffix.
- Matching rail code, rail length, number of blocks and any end machining.
- A clear photo of the old carriage and rail, or a machine drawing.
- Application, quantity and delivery city.
