Thk SRS9WGMUUCSS80LM(D) Linear Motion Bearing

Description:

The THK SRS9WGMUUCSS80LM(D) Linear Motion Bearing is a miniature precision linear guide assembly consisting of an SRS9WG wide-type LM block mounted on an 80 mm precision rail. Designed to provide smooth, high-accuracy linear motion in compact equipment, it offers four-way equal load capability, low friction, and reliable performance for precision positioning applications. Commonly installed in semiconductor equipment, laboratory instruments, medical devices, optical inspection systems, electronic manufacturing equipment, and compact automation machinery. Maintenance teams, machine builders, and system integrators use this linear guide assembly for OEM installations, repairs, retrofits, and replacement of miniature linear motion systems.

Applications:

The THK SRS9WGMUUCSS80LM(D) belongs to the THK SRS miniature LM Guide Series. The SRS9WG block is a full-ball, wide-block configuration that provides increased rigidity and load capacity while maintaining a compact profile. The UUCSS designation indicates double end seals with side seals for enhanced protection against contaminants, and the 80LM suffix specifies an 80 mm rail length. The SRS Series utilizes a four-way equal load design, enabling stable linear motion regardless of load direction. This assembly is well suited for precision measuring equipment, semiconductor manufacturing, medical devices, electronics assembly, compact robotics, and other applications requiring accurate, low-noise, miniature linear guidance.
