Thk RSR12ZM Linear Bearings Slide Assembly 14.1/2 Rails

Description:

The THK RSR12ZM Linear Bearings Slide Assembly is a miniature recirculating ball linear guide consisting of an RSR12ZM linear guide block mounted on a 14.5-inch (approximately 368 mm) precision guide rail. Commonly installed in semiconductor equipment, laboratory instruments, medical devices, compact automation systems, optical inspection machines, and precision measuring equipment. Maintenance teams, OEM machine builders, and system integrators use this assembly for machine repair, retrofit, and replacement of compact linear motion guide systems.

Applications:

The THK RSR12ZM linear guide assembly is designed for precision linear motion in compact industrial equipment where smooth travel, low friction, and high positioning accuracy are required. It is widely used in semiconductor manufacturing equipment, laboratory automation, medical diagnostic instruments, electronics assembly machines, optical inspection systems, pick-and-place equipment, miniature CNC machinery, robotics, and precision measuring devices.
