THOMSON TWN10 SUPER BEARING TWIN PILLOW BLOCKS UP TO 24 5/8

Description:

The Thomson TWN10 Super Ball Bushing Twin Pillow Block Bearing is used in precision linear motion systems to provide smooth, self-aligning linear travel on 5/8-inch (0.625-inch) Class L round shafts. Commonly installed in CNC machines, robotics, packaging equipment, automated assembly systems, material handling equipment, and industrial automation machinery, this closed-type twin pillow block features a lightweight 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 TWN10 is designed for end-supported shaft applications requiring high load capacity, precise positioning, and reliable linear guidance. Its twin pillow block configuration provides increased rigidity over a single bearing, while the self-aligning design compensates for minor shaft misalignment. It is widely used in CNC machinery, semiconductor equipment, packaging systems, pick-and-place machines, inspection equipment, automated manufacturing lines, and OEM linear motion assemblies.
