Thomson Industries TWN160PN Pillow Block Linear Bearing

Description:

The Thomson TWN160PN Super Twin Pillow Block Linear Bearing is used in precision linear motion systems requiring smooth, low-friction travel on a 1.000-inch precision shaft. Commonly installed in CNC machines, industrial automation equipment, packaging machinery, robotics, semiconductor equipment, and material handling systems, this twin self-aligning closed pillow block incorporates two Super Ball Bushing linear bearings within a lightweight aluminum housing to provide increased rigidity, high load capacity, and accurate linear guidance. Maintenance teams and system integrators use this bearing assembly for equipment repair, machine retrofits, linear bearing replacement, and precision motion control applications.

Applications:

The Thomson TWN160PN is commonly used in CNC machining centers, automated assembly lines, packaging equipment, inspection systems, woodworking machinery, medical equipment, and material handling systems where improved resistance to moment loads and smooth linear travel are required. Its twin-bearing configuration delivers greater stability than a single pillow block, making it suitable for demanding industrial linear motion applications.
