THOMSON SSEM40WW BALL BUSHING BEARING #289637

Description:

The Thomson SSEM40WW Super Smart Ball Bushing Linear Bearing is used in precision linear motion systems to provide smooth, self-aligning motion on 40 mm metric shafts. Commonly installed in CNC machines, industrial automation equipment, robotics, packaging machinery, semiconductor equipment, and material handling systems, this closed, adjustable linear bearing features dual integral wipers for superior contamination protection and extended operating 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 SSEM40WW is designed for end-supported metric shaft applications requiring high load capacity, low-friction operation, and automatic compensation for shaft and housing misalignment. It is widely used in CNC machining centers, automated assembly equipment, robotics, packaging systems, medical devices, semiconductor manufacturing, inspection equipment, and custom OEM machinery utilizing 40 mm Thomson MM shafting. Dual integral wipers help retain lubrication while protecting the bearing from dust and debris, ensuring reliable long-term performance.
