Thomson Industries SSU24OPN Open Linear Ball Bushing Bearing

Product Description

The THOMSON INDUSTRIES SSU24OPN is an open-style ball bushing linear bearing designed for precision linear motion applications. With a 1.5-inch bore diameter and a dynamic load capacity of 3,880 pounds, this bearing supports heavy-duty linear shaft systems where reliable, low-friction motion is required. The open configuration allows installation over a shaft without full disassembly of the surrounding assembly, making it a practical choice for retrofit and maintenance applications. It features a self-aligning design with 8 ball circuits, a 2.375-inch outside diameter, and a steel construction suited for industrial and mechanical drive systems. Typically installed by mechanical technicians, machine builders, or industrial maintenance professionals.

This bearing is used in linear motion systems across industrial machinery, automation equipment, and mechanical assemblies that require a round-bore, open-slot configuration. The open slot design allows the bearing to clear obstructing features along the shaft during installation without dismounting adjacent components. The self-aligning style compensates for minor shaft misalignment, reducing stress on the ball circuits during operation. It is a direct-fit replacement for applications requiring a 1.5-inch nominal bore open linear bearing with a 2.375-inch OD.

Key Features

• Open bearing style allows installation over the shaft without full system teardown
• 1.5-inch bore diameter with self-aligning design to compensate for minor shaft misalignment
• 3,880-pound dynamic load capacity for heavy-duty linear motion applications
• 8 open ball circuits for smooth, low-friction linear travel
• Steel construction for durability in industrial environments
• Minimum slot width of 0.75 inches accommodates shaft obstructions during install

Compatibility

Designed as an OEM-style replacement for open linear ball bushing bearings with a 1.5-inch bore and 2.375-inch outside diameter in round-bore linear shaft assemblies.

Installation Notes

Installation should be performed by a qualified mechanical technician familiar with linear motion components. Ensure the linear shaft and housing bore are clean and free of burrs before pressing or sliding the bearing into position. Do not apply force to the ball circuit retainers during installation, as damage to the ball tracks will affect load capacity and service life. Follow equipment manufacturer lockout and tagout procedures before servicing any machinery containing this bearing.
