THOMSON SPB24OPN PILLOW BLOCK LINEAR BEARING

Description:

The Thomson SPB24OPN Super Ball Bushing Bearing Pillow Block is used in precision linear motion systems requiring smooth, self-aligning travel on continuously supported 1-1/2-inch precision shafts. Commonly installed in CNC machines, industrial automation equipment, packaging machinery, robotics, material handling systems, and automated manufacturing equipment, this open, non-adjustable Super Ball Bushing® pillow block features a factory-installed recirculating ball bushing in a lightweight aluminum housing for accurate, low-friction linear motion. Maintenance teams and system integrators use this bearing for repair, retrofit, expansion, or replacement of continuously supported linear guide systems.

Applications:

The Thomson SPB24OPN is ideal for CNC machining centers, automated assembly equipment, packaging machinery, conveyor systems, robotics, inspection equipment, semiconductor manufacturing, and custom OEM machinery where continuously supported shafting provides increased rigidity and load capacity. Its open design allows the bearing to operate on fully supported shafts while maintaining precise alignment, smooth travel, and long service life.
