HGH15CA Linear Guide Block — 15 mm Square Type, Interchangeable
The HGH15CA is a 15 mm square-type heavy-load block for compact machine axes. Its mounting dimensions follow the HG standard, so it replaces an existing HG block without re-machining the carriage. Standard blocks are supplied as interchangeable units in Z0/ZA preload and C/H/P accuracy.

FAQ
| Is HGH15CA interchangeable with other HG-standard blocks? | Yes. Mounting hole spacing and rail profile follow the HG standard, so the block fits existing HG15 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 block-and-rail set only. |
| Which rail length do I need? | Use L = (n − 1) × P + 2 × E with P = 60 mm and E = 20 mm for HGR15. Tell us the length and hole count and we quote against it. |
