HGH Series Linear Guide Blocks
Square profile-rail blocks for high-rigidity machine tools and automation.
HGH-CA / HGH-HAOverview
HGH blocks use a square body with four-row Gothic-arch ball contact, so one block carries radial, reverse and side loads in the same assembly. The CA body is the standard length; HA is the longer body for higher moment loads. Sizes cover 15 mm to 65 mm rail widths, running on HGR rails cut to length and drilled to the standard pitch.
Key Features
- Four-direction equal load capacity
- CA standard and HA long block bodies
- Rail widths from 15 mm to 65 mm
- Matched HGR rails cut to length
