THK Co., Ltd. HSR30 Linear Bearing Guide Rail Assembly

The THK HSR30 Linear Bearing Guide Rail Assembly is a complete long-travel linear motion system featuring a 30 mm rail and a 2,160 mm (85 in) guide rail paired with three HSR30 bearing blocks, delivering high rigidity and precise, stable motion for long-axis travel in demanding automation. Built with THK's Four-Way Equal Load technology and a 45° four-row ball arrangement, it provides equal load ratings in radial, reverse radial, and lateral directions, with self-aligning raceways and low-friction operation. The assembly is designed for CNC machining centers, large CNC routers, robotic gantries, semiconductor equipment, material handling, inspection, and other automated production machinery, and is commonly used by maintenance teams, OEM machine builders, and system integrators for repair, retrofit, expansion, or replacement. Technical details include rail size 30 mm, rail length 2,160 mm (85 in), rail width 28 mm, rail height 26 mm, mounting hole type counterbored through holes, material hardened bearing steel, lubrication compatibility with grease or oil, and mounting orientations horizontal, vertical, or inverted; common replacements include HSR30-2160L, SHS30-2160L, and HSR30-2200L.
