THK SR-15V Lm System Linear Motion Guide Bearing Block

Description:

The THK SR-15V LM System is a compact radial-type linear motion guide block designed for SR15 guide rails, featuring a full-ball bearing design that provides smooth, accurate linear movement with high rigidity in space-constrained applications. Commonly installed in semiconductor equipment, laboratory automation, precision measuring instruments, medical devices, packaging machinery, and factory automation systems where compact linear guidance is required. Maintenance teams and system integrators use this linear guide block for OEM replacement, machine repair, retrofit projects, and the development of precision motion systems. 

Applications:

The THK SR-15V is engineered for compact automation equipment requiring precise positioning, low friction, and stable linear travel. Its short-block design offers excellent space savings while maintaining high accuracy and rigidity, making it ideal for pick-and-place machines, electronic assembly equipment, optical inspection systems, CNC auxiliary axes, medical instruments, and compact industrial robots.
