HGH25CA Linear Guide Block — 25 mm Square Type, Interchangeable
The HGH25CA is a 25 mm square-type heavy-load block, the most common size on machining centres and automation gantries. It uses the HG mounting pattern, so existing drawings and bolt holes carry over. Interchangeable blocks cover Z0/ZA preload and C/H/P accuracy; SP/UP and ZB come as matched sets.

FAQ
| Is HGH25CA interchangeable with other HG-standard blocks? | Yes. Mounting hole spacing and rail profile follow the HG standard, so the block fits existing HG25 rails. |
| Can the block and rail be bought separately? | Yes, in Z0/ZA preload and C/H/P accuracy. SP/UP accuracy and ZB preload are supplied as a matched set only. |
| Which rail length do I need? | Use L = (n − 1) × P + 2 × E with P = 60 mm and E = 20 mm for HGR25. Standard lengths run from 220 mm to 1240 mm. |
