Thomson SSEM25WW Ball Bushing Metric OD 40mm Inner Ring Width 43.7mm

Description:

The Thomson SSEM25WW Super Smart Ball Bushing Linear Bearing is used in precision linear motion systems to provide smooth, self-aligning motion on 25 mm metric shafts. Commonly installed in CNC machines, industrial automation equipment, robotics, packaging machinery, semiconductor systems, and material handling equipment, this closed, adjustable linear bearing features dual integral wipers for enhanced contamination protection and extended service life. Maintenance teams and system integrators use this part for repair, retrofit, expansion, or replacement of end-supported metric linear shaft systems.

Applications:

The Thomson SSEM25WW is designed for end-supported metric shaft applications requiring high load capacity, precise linear guidance, and automatic compensation for shaft and housing misalignment. It is commonly used in CNC machining centers, automated assembly equipment, robotics, inspection systems, medical devices, packaging machinery, and custom OEM equipment utilizing 25 mm Thomson MM shafting. Dual integral wipers help retain lubrication while preventing dirt and debris from entering the bearing, resulting in smoother operation and longer service life.
