Thomson TWN10 Twin Pillow Block Linear Bearing

Description:

The Thomson TWN10 Twin Pillow Block Linear Bearing is used in precision linear motion systems requiring stable, low-friction travel on a 0.625-inch precision shaft. Commonly installed in CNC machines, industrial automation equipment, packaging machinery, semiconductor systems, robotics, and material handling equipment, this twin closed pillow block incorporates two self-aligning Super Ball Bushing bearings in a single aluminum housing to provide increased rigidity, improved load distribution, and smooth linear motion. Maintenance teams, machine builders, and system integrators use this bearing assembly for equipment repair, linear bearing replacement, machine retrofits, and precision motion control applications.

Applications:

The Thomson TWN10 is commonly used in CNC machining centers, automated assembly systems, packaging equipment, inspection machinery, woodworking equipment, medical devices, and industrial automation where enhanced stability and accurate linear guidance are required. Its twin-bearing design provides greater support and resistance to moment loads than a single pillow block, making it ideal for demanding linear motion applications.
