Thomson Industries SSUPBO12 Pillow Block Linear Bearing

Product Description

The THOMSON INDUSTRIES SSUPBO12 is an open single pillow block linear bearing designed for use in linear motion systems requiring precise shaft guidance and load support. Built with a ball bushing design and self-aligning capability, this bearing accepts a 0.75-inch round bore shaft and delivers a single dynamic load capacity of 1,130 pounds, with a twin dynamic load capacity of 2,260 pounds. Constructed from steel, it is suited for industrial machinery, automation equipment, and mechanical assemblies where reliable linear travel and structural rigidity are essential. Installation is typically performed by mechanical technicians or industrial maintenance professionals.

This pillow block bearing is used in linear guide applications across a range of industrial and light manufacturing environments. Its open bearing style allows for easy shaft insertion and removal during maintenance. The self-aligning design compensates for minor shaft misalignment, reducing stress on the shaft and bearing assembly. At 0.75 inches bore diameter, it fits standard 3/4-inch shafting commonly found in conveyor systems, actuators, and precision positioning equipment.
