THK HSR15B Precision Linear Bearing Way Set Assembly

The THK HSR15B Precision Linear Bearing Way Set 32-Inch is a complete linear motion assembly that pairs one 32-inch (812.8 mm) HSR15 guide rail with one HSR15B flange-type bearing block, delivering smooth, precise, high-rigidity motion with THK's Four-Way Equal Load technology to support equal loads in radial, reverse-radial, and lateral directions. Commonly installed in CNC machine tools, industrial robots, semiconductor equipment, packaging machinery, and factory automation systems, it is used by maintenance teams, OEM machine builders, and system integrators for machine repair, retrofit, expansion, and replacement. Technical specifications include: guide rail length 32 in (812.8 mm); rail width 15 mm; guide block model HSR15B (flange type); single bearing block; block height 24 mm, width 47 mm, length 56.6 mm; mounting dimensions B × C 38 mm × 30 mm; rail mounting hole diameter 4.5 mm with 60 mm pitch; basic dynamic load rating 10.9 kN; basic static load rating 15.7 kN; material hardened bearing steel; lubrication compatible with grease or oil; grease nipple PB1021B. Features encompass high rigidity, compact flange design, self-adjusting capability, high positioning accuracy, low-friction operation, and long service life.
