Thomson Industries SSUPB10 Pillow Block Linear Bearing

Product Description

The THOMSON INDUSTRIES SSUPB10 is a closed single pillow block linear bearing designed for use in linear motion systems requiring precise shaft guidance and load support. Built with a 0.625 inch bore diameter and a ball bushing design, it delivers a single dynamic load capacity of 620 pounds and a twin dynamic load capacity of 1,240 pounds. The steel construction provides durability in demanding industrial environments. Self-aligning capability compensates for minor shaft misalignment, reducing wear on both the bearing and the shaft. This unit is installed by mechanical technicians and maintenance professionals in automated machinery, material handling equipment, and motion control systems.

The SSUPB10 is suited for light to medium-duty linear motion applications in industrial and commercial settings. Its closed bearing style protects internal ball bushing components from contaminants, making it appropriate for environments with dust or debris exposure. The round bore accepts 5/8 inch shafting directly. Overall block dimensions of 4.0 inches in length, 2.5 inches in width, and 1.63 inches in height make it a compact fit in standard pillow block mounting configurations. Center-to-center bore spacing of 1.94 inches aligns with common mounting hole patterns for ease of installation.

Compatibility

Designed as an OEM-style replacement or upgrade for closed single pillow block linear bearing assemblies using 5/8 inch round bore shafting in standard industrial linear motion systems.

Installation Notes

Installation should be performed by a qualified mechanical technician. De-energize and lock out all power to the machine before servicing any linear motion components. Ensure the mounting surface is flat and clean before securing the pillow block to prevent misalignment under load. Do not exceed the rated dynamic load capacity during operation, and verify shaft diameter matches the 0.625 inch bore before assembly.
