Thomson SSUTWN16 Twin Pillow Block Bearing 1In Bore 4 Bolt 3800lb

Description:

The Thomson SSUTWN16 Super Smart Ball Bushing Twin Pillow Block Bearing is used in precision linear motion systems to provide smooth, self-aligning motion on 1.000-inch Class L round shafts. Commonly installed in CNC machines, industrial automation equipment, robotics, packaging machinery, semiconductor equipment, and material handling systems, this closed twin pillow block features two factory-installed Super Smart Ball Bushings®, an aluminum housing, four-bolt mounting, and a dynamic load capacity of 3,800 lbf for end-supported shaft applications. Maintenance teams and system integrators use this part for repair, retrofit, expansion, or replacement of precision round shaft linear guide systems.

Applications:

The Thomson SSUTWN16 is designed for end-supported Class L shaft applications requiring increased rigidity, high load capacity, and long service life. Its twin-bearing configuration provides twice the load capacity and significantly longer travel life than comparable single-bearing pillow blocks, making it ideal for CNC machining centers, automated assembly systems, robotics, packaging equipment, semiconductor manufacturing, inspection systems, and custom OEM linear motion applications.
