Thomson SPB24 Super Ball Bushing Bearing Pillow Block

Description:

The Thomson SPB24 Super Ball Bushing Bearing Pillow Block is used in precision linear motion systems to provide smooth, self-aligning travel on 1-1/2-inch precision shafts. Commonly installed in CNC machines, industrial automation equipment, packaging machinery, material handling systems, robotics, and heavy-duty manufacturing equipment, this closed-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 end-supported linear guide systems.

Applications:

The Thomson SPB24 Super Ball Bushing Bearing Pillow Block is widely used in factory automation, CNC machining centers, automated assembly equipment, packaging systems, conveyor equipment, material handling machinery, robotics, and custom OEM machines requiring precise linear guidance, high load capacity, and reliable performance. Its self-aligning design compensates for minor shaft misalignment while providing long service life and smooth operation.
