Thomson TWN6 Super Pillow Block Bearing 200lbs Load 3/8 Bore Closed

Description:

The Thomson TWN6 Super Ball Bushing Twin Pillow Block Bearing is used in precision linear motion systems to provide smooth, self-aligning linear travel on 3/8-inch (0.375-inch) Class L round shafts. Commonly installed in CNC machines, robotics, packaging equipment, automated assembly systems, inspection equipment, and industrial automation machinery, this closed-type twin pillow block features an aluminum housing, integral double-acting seals, and a self-aligning Super Ball Bushing bearing for accurate, low-friction linear motion. Maintenance teams and system integrators use this part for repair, retrofit, expansion, or replacement of precision linear guide systems.

Applications:

The Thomson TWN6 is designed for end-supported shaft applications requiring high stability, accurate positioning, and smooth linear travel. Its twin pillow block configuration provides greater rigidity than a single bearing while the self-aligning design compensates for minor shaft misalignment. It is widely used in machine tools, robotics, semiconductor equipment, packaging machinery, pick-and-place systems, laboratory automation, and OEM linear motion equipment.
