Thomson SPB24OPN Super Ball Bushing Bearing Pillow Block

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 heavy-duty manufacturing equipment, this open-type Super Ball Bushing® pillow block features an aluminum housing with a self-aligning recirculating ball bearing 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 widely used in factory automation, CNC machining centers, automated assembly equipment, conveyor systems, packaging machinery, robotics, inspection systems, and custom OEM equipment where continuously supported shafting provides increased rigidity and load capacity. Its open-style design allows the bearing to travel along fully supported shafts while maintaining smooth, precise linear movement and compensating for minor shaft misalignment.
