THK Co., Ltd. HSR15B Precision Linear Bearing Way Set

Description:

The THK HSR15B Precision Linear Bearing Way Set is a complete linear motion assembly consisting of one 9-inch (228.6 mm) HSR15 guide rail and one HSR15B flange-type linear guide block. Designed with THK's Four-Way Equal Load technology, it delivers smooth, high-precision, and high-rigidity linear motion while supporting equal loads in radial, reverse-radial, and lateral directions. Commonly installed in CNC machines, industrial robots, semiconductor equipment, packaging machinery, and factory automation systems, this assembly is used by maintenance teams, OEM machine builders, and system integrators for machine repair, retrofit, expansion, and replacement.

Applications:

The THK HSR15B Linear Bearing Way Set is widely used in compact CNC machining centers, robotic positioning systems, semiconductor manufacturing equipment, optical inspection machines, medical devices, automated assembly systems, packaging equipment, and precision industrial automation requiring smooth, low-friction, and highly accurate linear motion. The compact 9-inch rail makes it well suited for short-travel positioning applications.
