THK HSR15 Recirculating Ball Linear Guide Rail

The THK HSR15 Recirculating Ball Linear Guide Rail is a precision linear motion assembly that combines a 14-inch HSR15 guide rail with two HSR15R bearing blocks for smooth, high-rigidity movement. Featuring THK's Four-Way Equal Load design, it delivers equal load capacity in radial, reverse-radial, and lateral directions, with a dual-block configuration that improves stability and load distribution along the 14-inch rail. This top-mounted assembly—often used in CNC machines, industrial robots, semiconductor equipment, packaging machinery, and automated manufacturing systems—serves maintenance teams, OEM machine builders, and system integrators for repair, retrofit, expansion, or replacement. Key specifications include guide rail size HSR15; guide rail length 14 in (355.6 mm); rail width 15 mm; number of bearing blocks: 2 (bearing blocks: HSR15R); block dimensions 28 mm (H) × 34 mm (W) × 39.4 mm (L); basic dynamic load rating: 10.9 kN per block; basic static load rating: 15.7 kN per block; material: hardened bearing steel; lubrication: grease or oil compatible.
