HGH-30-HA-ZOC / ZAC is a high-precision linear guide block from the HIWIN HG series (size 30), designed for super heavy-load applications such as CNC machines, VMCs, and industrial automation systems. It features a square-type (H) block with top mounting (A type) and is compatible with 30 mm linear guide rails. The “HA” model indicates super heavy load capacity with high rigidity, making it suitable for demanding and high-accuracy operations. The block uses a ball-type rolling mechanism to ensure smooth, low-friction linear motion and long service life.
