HGH30CA Linear Guide Block — 30 mm Square Type, Interchangeable
The HGH30CA is a 30 mm square-type block for high-load machine axes such as gantry machining centres and heavy automation. It keeps the HG mounting dimensions, so it drops into existing carriage designs. Interchangeable supply covers Z0/ZA preload and C/H/P accuracy.

FAQ
| Is HGH30CA interchangeable with other HG-standard blocks? | Yes. Mounting hole spacing and rail profile follow the HG standard, so the block fits existing HG30 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 = 80 mm and E = 20 mm for HGR30. Maximum single-piece length is 4000 mm. |
