THK HSR15B Precision Linear Bearing Way Set Assembly

Description:

The THK HSR15B Precision Linear Bearing Way Set 32-Inch is a complete linear motion assembly consisting of one 32-inch (812.8 mm) HSR15 guide rail and one HSR15B flange-type linear guide block. Designed with THK's Four-Way Equal Load technology, it delivers smooth, precise, and high-rigidity linear motion while supporting 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, this assembly is used by maintenance teams, OEM machine builders, and system integrators for machine repair, retrofit, expansion, and replacement.

Applications:

The THK HSR15B Precision Linear Bearing Way Set 32-Inch is ideal for long-travel CNC machining centers, automated production equipment, robotic gantries, semiconductor manufacturing systems, precision inspection machines, medical devices, and industrial automation applications requiring high positioning accuracy, smooth low-friction motion, and excellent rigidity over an extended travel length.
