FAQ
| Is HGW20CC interchangeable with HGH20CA? | They share the same HGR20 rail, but the block bodies differ: HGW is flange type, HGH is square type. |
| 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 HGR20. |
