Thomson Industries SSUPBO24 Pillow Block Linear Bearing

Product Description

The THOMSON INDUSTRIES SSUPBO24 is an open single pillow block linear bearing designed for ball bushing linear motion applications. With a 1.5-inch bore diameter and a single dynamic load capacity of 3880 pounds (7760 pounds twin configuration), this bearing supports demanding linear guide systems in industrial and automation environments. The self-aligning design compensates for minor shaft misalignment, reducing stress on mating components. Constructed from steel, the SSUPBO24 delivers the structural integrity required for high-cycle linear motion under significant radial loads. Licensed HVAC, mechanical, and industrial service technicians working with linear actuators and motion systems will find this bearing a direct-fit replacement option.

The SSUPBO24 is suited for linear motion systems where a pillow block mounting configuration is required. The open bearing style allows for easy shaft insertion and removal without full disassembly, which is practical in maintenance-heavy environments. Typical applications include conveyor systems, automated assembly equipment, and linear actuator assemblies where repeatable, low-friction shaft travel is critical. The round bore accepts a 1.5-inch shaft and is compatible with standard Thomson ball bushing shaft systems.

Key Features

• 1.5-inch (38.10 mm) round bore diameter for standard shaft fitment
• Single dynamic load capacity of 3880 pounds; twin configuration rated to 7760 pounds
• Open bearing style for straightforward shaft installation and removal
• Self-aligning design compensates for minor shaft misalignment
• Steel construction for durability under high-cycle, high-load linear motion
• Center-to-center bore length of 3.75 inches for standard pillow block bolt patterns

Compatibility

Designed as an OEM-style replacement pillow block linear bearing for ball bushing linear motion systems requiring a 1.5-inch bore round shaft configuration.

Installation Notes

Installation should be performed by a qualified mechanical technician familiar with linear motion systems. De-energize all connected machinery and relieve any load or tension on the shaft before removing or installing this bearing. Use standard pillow block mounting hardware appropriate to the application load rating, and verify shaft diameter and surface finish meet Thomson specifications before assembly. Follow applicable machinery safety standards and the equipment manufacturer's guidelines during installation.
