Direct Replacement: Fully interchangeable with HIWIN HG25 series blocks and rails - same mounting dimensions, no modification or re-drilling on your machine.
Four-Row Circular-Arc Design: Equal load ratings in radial, reverse radial and lateral directions, delivering high rigidity and long service life.
Self-Aligning Capability: 45 contact angle absorbs installation errors and base irregularities, keeping motion smooth even on imperfect mounting surfaces.
Ball Retainer Included: The retainer holds the balls in place, so the block never scatters balls when removed from the rail - safer and faster maintenance.
Precision Options Available: Supplied in C / H / P accuracy grades with ZF / Z0 / Z1 preload to match your machine's requirements.
Custom Rail Length: Rails cut to any length from 100 mm to 4000 mm, end-machined and deburred to protect the ball circuit.
