Thomson Industries SPB16OPN Super Pillow Block Bearing

Description:

The Thomson Industries SPB16OPN Super Pillow Block Bearing is used in precision linear motion systems to provide smooth, self-aligning linear support on continuously supported 1.000-inch precision shafting. Commonly installed in CNC machines, industrial automation equipment, packaging machinery, robotics, and material handling systems requiring accurate, low-friction linear guidance. Maintenance teams and system integrators use this pillow block bearing for machine repairs, automation retrofits, OEM installations, and replacement of worn linear bearings to restore reliable and precise motion control. 

Applications:

The Thomson Industries SPB16OPN Super Pillow Block Bearing is designed for continuously supported shaft applications where high load capacity, self-alignment, and dependable linear motion are essential. It is widely used in CNC machining centers, semiconductor equipment, automated assembly systems, inspection machinery, pick-and-place equipment, and custom OEM automation systems. Its open-type design allows operation on supported shafting while the integral double-acting seals help protect against contaminants and retain lubrication.
