Thomson SSUTWNO16 Super Smart Twin Pillow Block Ball Bearing Open Shaft 1.0

Description:

The Thomson SSUTWNO16 Super Smart Twin Pillow Block Ball Bearing is used in precision linear motion systems to provide smooth, self-aligning linear travel on 1.000-inch Class L continuously supported round shafts. Commonly installed in CNC machines, industrial automation equipment, robotics, packaging machinery, semiconductor equipment, and material handling systems, this open-style adjustable twin pillow block features two factory-installed Super Smart Ball Bushings®, an aluminum housing, and integral double-acting seals for high-load linear guidance. Maintenance teams and system integrators use this part for repair, retrofit, expansion, or replacement of continuously supported round shaft linear guide systems.

Applications:

The Thomson SSUTWNO16 is designed for continuously supported Class L shaft applications requiring high rigidity, accurate positioning, and extended service life. Its open twin-bearing configuration delivers approximately twice the load capacity and significantly longer travel life than comparable single-bearing units, making it ideal for CNC machining centers, automated assembly equipment, robotics, semiconductor manufacturing, packaging machinery, inspection systems, and other precision OEM linear motion applications.
