Looking for a HIWIN RG guideway dealer in Delhi? A block code such as RGH25CA is a useful start, but the rail length, number of blocks, preload, accuracy class and mounting drawing are needed for a complete enquiry.

Can an RG block replace an HG block of the same size?
Do not assume so. RG is HIWIN's roller guideway family while HG is a ball guideway family. Even when a size number looks similar, block geometry, rail profile, load rating and mounting details may differ. Compare the complete assembly against the machine maker's drawing rather than choosing by nominal size.
- Full RGH or RGW carriage designation, including suffixes.
- Matching rail code, rail length and mounting-hole layout.
- Carriage style, mounting height and block quantity per rail.
- Required preload, accuracy class and lubrication arrangement.
For a replacement machine, a clear photo of the old rail and block markings helps the team identify the correct family before discussing availability.
