Thomson SS6U12 Super Smart Ball Bushing Closed Linear Bearings 3/4 Bore 1-5/8

Description:

The Thomson SS6U12 Super Smart Ball Bushing Closed Linear Bearing is used in precision linear motion systems to provide smooth, self-aligning travel on 3/4-inch Class L shafts. Commonly installed in CNC machines, industrial automation equipment, packaging machinery, robotics, inspection systems, and material handling equipment, this closed, adjustable Super Smart Ball Bushing® features patented recirculating ball technology that delivers significantly higher load capacity and longer service life than conventional linear bearings. Maintenance teams and system integrators use this part for repair, retrofit, expansion, or replacement of end-supported linear shaft systems.

Applications:

The Thomson SS6U12 is designed for precision linear motion applications requiring high load capacity, smooth travel, and automatic compensation for shaft and housing misalignment. It is commonly used in CNC machining centers, automated assembly equipment, robotics, packaging machinery, semiconductor manufacturing, medical devices, inspection equipment, and custom OEM machinery operating on 3/4-inch end-supported shafts.
