THK Co., Ltd. SR15V Linear Bearing Guide System

Description:

The THK SR15V Linear Bearing Assembly is a compact radial-type linear motion guide consisting of an SR15V bearing block mounted on a 160 mm SR15 guide rail. It is designed to deliver smooth, high-precision linear movement with low friction and high rigidity in compact industrial automation systems. Commonly installed in semiconductor equipment, laboratory automation, medical devices, precision measuring instruments, packaging machinery, and small CNC or robotic systems. Maintenance teams and system integrators use this assembly for OEM replacement, machine repair, retrofit projects, and the construction of precision linear motion systems.

Applications:

The THK SR15V linear bearing assembly is engineered for compact precision equipment requiring accurate positioning, stable linear travel, and long service life. Its full-ball radial guide design makes it ideal for electronic assembly machines, optical inspection systems, pick-and-place equipment, laboratory instruments, automated production equipment, and other factory automation applications where space-saving linear guidance is essential.
