Thk RSR9KM Linear Bearing 4x M3 Tapped Holes Rail 155mm x 9mm x 6mm

Description:

The THK RSR9KM Linear Bearing with 155 mm Rail is a miniature precision linear motion guide assembly consisting of an RSR9KM recirculating ball bearing block mounted on a 155 mm long, 9 mm wide, and 6 mm high guide rail. Designed for compact, high-precision linear motion applications, it delivers smooth travel, low friction, high rigidity, and excellent positioning accuracy in space-constrained equipment. Commonly installed in laboratory instruments, semiconductor equipment, medical devices, optical inspection systems, compact automation equipment, and precision measuring machines, this assembly is used by maintenance teams, OEM machine builders, and system integrators for equipment repairs, retrofits, and replacement of miniature linear guide systems.

Applications:

The THK RSR9KM miniature linear guide assembly is widely used in semiconductor manufacturing equipment, laboratory automation systems, medical devices, optical inspection machines, compact CNC equipment, precision measuring instruments, electronics assembly equipment, pick-and-place machines, miniature robotic systems, and other applications requiring compact, accurate, and smooth linear motion.
