Thomson SSUPBO8 Super Pillow Block Shaft Diameter 0.5 Flange 2 x 1.5

Description:

The Thomson SSUPBO8 Super Smart Ball Bushing Open Pillow Block Linear Bearing is used in precision linear motion systems to provide smooth, self-aligning linear motion on 0.500-inch (1/2-inch) precision shafts. Commonly installed in CNC machines, industrial automation equipment, robotics, packaging machinery, semiconductor equipment, and material handling systems, this open-style pillow block features a factory-installed Super Smart Ball Bushing®, adjustable preload, aluminum housing, integral double-acting seals, and a compact 2.0 × 1.5-inch mounting footprint for continuously supported shaft applications. Maintenance teams and system integrators use this part for repair, retrofit, expansion, or replacement of supported round shaft linear guide systems.

Applications:

The Thomson SSUPBO8 is designed for continuously supported Class L round shaft applications where high precision, low-friction travel, adjustable bearing clearance, and automatic self-alignment are required. It is widely used in CNC routers, automated assembly equipment, robotics, semiconductor manufacturing, packaging machinery, inspection systems, medical equipment, and OEM automation requiring rigid shaft support and accurate linear guidance.
