HIWIN HGH25CC Linear Guide Slider
The HGH25CC is a heavy load square type linear guide slider from HIWIN's HG Series, engineered for seamless integration with HGR25 profile rails. It features a four-row, 45° contact angle ball design that delivers equal load capacity across radial, reverse radial, and lateral directions, complemented by self-aligning capability to absorb minor installation errors.
he HGH25CC is a heavy load square type linear guide slider from HIWIN's HG Series, engineered for seamless integration with HGR25 profile rails. It features a four-row, 45° contact angle ball design that delivers equal load capacity across radial, reverse radial, and lateral directions, complemented by self-aligning capability to absorb minor installation errors. The square block design enables secure top mounting, making it ideal for applications demanding high rigidity, balanced load distribution, and precise linear motion in industrial automation and machine tool systems.
