THK HSR15 Recirculating Ball Linear Guide Rail

Description:

The THK HSR15 Linear Rail Assembly is a precision recirculating ball linear motion system consisting of one 14-inch (355.6 mm) HSR15 guide rail and two HSR15 linear bearing blocks. It delivers smooth, accurate, and high-rigidity linear motion with THK's Four-Way Equal Load design, providing equal load capacity in radial, reverse-radial, and lateral directions. Commonly installed in CNC machines, industrial robots, semiconductor equipment, packaging machinery, and automated manufacturing systems, this assembly is used by maintenance teams, OEM machine builders, and system integrators for machine repair, retrofit, expansion, and replacement.

Applications:

The THK HSR15 Linear Rail with two bearing blocks is ideal for CNC machining centers, robotic positioning systems, semiconductor manufacturing equipment, medical devices, automated inspection systems, packaging equipment, electronics assembly lines, and precision factory automation requiring rigid, low-friction, and high-accuracy linear motion. The dual-block configuration provides enhanced stability and load distribution over the 14-inch guide rail.
