THOMSON SSEM20OPNWW LINEAR BALL BUSHING BEARING 20MM BORE SELF-ALIGNING NSMP

Description:

The Thomson SSEM20OPNWW Super Smart Ball Bushing Linear Bearing is used in precision linear motion systems to provide smooth, self-aligning motion on 20 mm continuously supported shafts. Commonly installed in CNC machines, industrial automation equipment, robotics, packaging machinery, semiconductor systems, and material handling equipment, this open, adjustable linear bearing features dual integral wipers for enhanced contamination protection and long service life. Maintenance teams and system integrators use this part for repair, retrofit, expansion, or replacement of continuously supported metric linear shaft systems.

Applications:

The Thomson SSEM20OPNWW is designed for continuously supported 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 systems, robotics, inspection equipment, packaging machinery, medical devices, and OEM automation equipment utilizing 20 mm supported metric shafting. The open bearing design accommodates supported rails, while dual wipers help retain lubrication and prevent contaminants from entering the bearing.
