THK RSR12WVMUU310LM LINEAR GUIDE BLOCK RAIL

Description:

The THK RSR12WVMUU310LM Linear Guide Block & Rail Assembly is a miniature wide-type recirculating ball linear motion guide consisting of an RSR12WVM bearing block mounted on a 310 mm precision guide rail. Designed for compact automation and high-precision positioning applications, the wide block configuration provides increased rigidity, smooth low-friction travel, and equal load capacity in all four directions. Commonly installed in semiconductor equipment, laboratory instruments, 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. The "UU" designation indicates double end seals for improved contamination protection, while the "M" suffix denotes stainless steel construction for enhanced corrosion resistance.

Applications:

The THK RSR12WVMUU310LM linear guide assembly is widely used in semiconductor manufacturing equipment, laboratory automation systems, medical instruments, optical inspection equipment, electronics assembly machines, compact CNC systems, pick-and-place equipment, miniature robotic systems, precision measuring instruments, and other applications requiring compact, accurate, and reliable linear motion with high rigidity.
