Thomson TWN6 Danaher Motion Linear Ball Bushing Bearing

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, laboratory equipment, and industrial automation machinery, this closed-type twin pillow block features a lightweight aluminum housing, integral double-acting seals, and a Super Ball Bushing linear bearing for accurate, low-friction, and repeatable 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 smooth linear travel, precise positioning, and reliable load support. Its twin pillow block construction provides increased rigidity compared to single-bearing designs, while the self-aligning bearing compensates for minor shaft misalignment. It is commonly used in CNC machinery, robotics, semiconductor equipment, packaging systems, automated inspection equipment, medical devices, and OEM linear motion assemblies.
