Thomson SRM25T1 Shaft Support Rail Standard Profile

Description:

The Thomson SRM25T1 Shaft Support Rail is used in precision linear motion systems to provide rigid support for 25 mm Thomson 60 Case® linear shafts. Commonly installed in CNC machines, industrial automation equipment, robotics, packaging machinery, and material handling systems, this predrilled standard-profile aluminum support rail minimizes shaft deflection while maintaining accurate linear guidance. Maintenance teams and system integrators use this part for repair, retrofit, expansion, or replacement of continuously supported linear shaft systems.

Applications:

The Thomson SRM25T1 support rail is designed for continuously supported shaft applications requiring improved rigidity and precise linear motion. It is widely used in CNC machining centers, automated assembly equipment, robotics, semiconductor manufacturing, packaging systems, inspection equipment, and custom OEM machinery utilizing Thomson open-style Ball Bushing® linear bearings. The predrilled T1 hole pattern simplifies installation while providing a secure mounting solution for demanding industrial environments.
