THK Co., Ltd. 2SRS12WMUU470LM Linear Ball Bearing Carriage

Description:

The THK 2SRS12WMUU470LM Linear Ball Bearing Carriage is a precision miniature LM Guide assembly consisting of two SRS12WM ball bearing carriages mounted on a 470 mm precision rail. Designed for compact, high-accuracy linear motion, it provides smooth travel, low friction, and four-way equal load capability for demanding automation and positioning applications. Commonly installed in semiconductor equipment, medical devices, laboratory instruments, electronics manufacturing systems, optical inspection equipment, and precision automation machinery. Machine builders, maintenance technicians, and system integrators use this assembly for new equipment construction, retrofits, repairs, and replacement of miniature linear guide systems.

Applications:

The THK 2SRS12WMUU470LM belongs to THK's SRS miniature LM Guide Series and features the SRS12WM wide-block configuration, which offers increased rigidity and load capacity compared to the standard narrow block. The assembly includes two SRS12WMUU carriages with double end seals mounted on a 470 mm stainless steel rail. Its four-way equal-load recirculating ball design ensures smooth, accurate motion while maintaining compact dimensions, making it ideal for robotic equipment, pick-and-place systems, precision measuring instruments, laboratory automation, and compact manufacturing equipment where reliability and positioning accuracy are essential.
