THK RSR12WZM Linear Motion Ball Bearing Slide

Description:

The THK RSR12WZM Linear Motion Ball Bearing Slide is a miniature wide-type recirculating ball linear guide assembly consisting of an RSR12WZM bearing block mounted on a 390 mm precision guide rail. Designed for compact, high-precision linear motion applications, the wide-block configuration provides increased rigidity, smooth low-friction travel, and equal load capacity in all four directions while maintaining a compact footprint. Commonly installed in semiconductor manufacturing equipment, laboratory automation systems, medical devices, optical inspection equipment, electronics assembly machines, and precision measuring systems, this linear guide assembly is used by maintenance teams, OEM machine builders, and system integrators for equipment repairs, retrofits, and replacement of miniature linear motion components. THK's RSR series utilizes stainless steel construction and recirculating ball technology for high accuracy and excellent corrosion resistance.

Applications:

The THK RSR12WZM linear guide assembly is widely used in semiconductor processing equipment, laboratory instruments, medical diagnostic systems, optical inspection machines, electronics manufacturing equipment, compact CNC machines, pick-and-place systems, miniature robotic assemblies, precision measuring instruments, and other industrial automation applications requiring compact, smooth, and accurate linear motion with high rigidity.
