Thomson Industries SSUPBO20 Pillow Block Linear Bearing

Product Description

The THOMSON INDUSTRIES SSUPBO20 is an open single pillow block linear bearing designed for use in linear motion systems requiring precision shaft support and axial load management. Built with a steel ball bushing construction, this bearing features a 1.25-inch bore diameter and delivers a single dynamic load capacity of 2350 pounds, with a twin dynamic load capacity of 4700 pounds. The self-aligning design compensates for minor shaft misalignment, reducing wear and extending service life. Maintenance technicians and mechanical assemblers working on industrial linear motion equipment are the primary installers of this component.

This pillow block bearing is suited for linear slide assemblies, automation equipment, conveyor systems, and other machinery requiring guided shaft support. Its open bearing style allows for easy shaft installation and facilitates access for periodic inspection and lubrication. The self-alignment capability makes it appropriate for applications where precise housing alignment cannot always be guaranteed. This bearing is typically used in light to medium industrial settings where repeatable linear motion and consistent load support are required.

Key Features

• 1.25-inch bore diameter with round bore type for standard shaft compatibility
• Single dynamic load capacity of 2350 pounds; twin dynamic load capacity of 4700 pounds
• Open bearing style for simplified shaft installation and maintenance access
• Self-aligning design to compensate for minor shaft or housing misalignment
• Steel construction for durability in industrial linear motion applications
• Overall dimensions of 7.5 inches length, 4 inches width, and 2.56 inches height

Compatibility

Designed as an OEM-style replacement or direct-fit linear bearing for industrial machinery and automation equipment using 1.25-inch diameter shafts in pillow block linear bearing configurations.

Installation Notes

Installation should be performed by qualified mechanical technicians familiar with linear motion components. De-energize and lock out all power sources before servicing any machinery in which this bearing is installed. Ensure the mounting surface is clean and flat before securing the pillow block, and verify shaft alignment within the self-aligning range before final torque of mounting fasteners. Consult applicable machinery safety standards and the equipment manufacturer documentation for bearing preload and lubrication intervals.
