FAQ
| Is HGH45CA interchangeable with other HG-standard blocks? | Yes. Mounting hole spacing and rail profile follow the HG standard, so the block fits existing HG45 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 = 105 mm and E = 22.5 mm for HGR45. |
