Thomson SPB16ADJ Super Ball Bushing Linear Bearing

Description:

The Thomson SPB16ADJ Super Ball Bushing Linear Bearing is used in precision linear motion systems to provide smooth, self-aligning travel on 1-inch precision shafts with adjustable preload capability for enhanced accuracy. Commonly installed in CNC machines, industrial automation equipment, packaging machinery, material handling systems, robotics, and inspection equipment, this closed-type Super Ball Bushing® pillow block features an adjustable aluminum housing with recirculating ball bearings for precise, low-friction linear motion. Maintenance teams and system integrators use this bearing for repair, retrofit, expansion, or replacement of end-supported linear guide systems requiring adjustable bearing fit.

Applications:

The Thomson SPB16ADJ is widely used in factory automation, CNC machining centers, semiconductor equipment, packaging machinery, medical equipment, automated assembly systems, conveyor equipment, and custom OEM machinery requiring precise linear guidance with adjustable preload. Its self-aligning, adjustable design compensates for minor shaft misalignment while allowing users to fine-tune bearing clearance for maximum positioning accuracy and long service life.
