Thomson Industries PR1500 Steel Internal Retaining Ring

Product Description

The THOMSON INDUSTRIES PR1500 is a steel internal push-in retaining ring designed to secure components within a bore or housing during linear bearing assembly. With an inside diameter of 1.875 inches, this ring seats firmly in the groove of the housing to prevent axial movement of the retained part. It is used in light industrial, automation, and motion control applications where reliable component retention is essential. Maintenance technicians and mechanical assemblers install this ring as part of standard linear bearing service or rebuild work.

This retaining ring is intended for use with Thomson linear bearing assemblies. The push-in style allows for straightforward installation without specialized tooling in most standard groove configurations. It is a direct-fit replacement part for maintaining proper bearing retention in linear motion systems across industrial and OEM equipment applications.

Installation Notes

Mechanical technicians or assemblers should de-energize and lock out any equipment before servicing linear bearing assemblies.

Use appropriate retaining ring pliers or a push-in installation tool to seat the ring fully and evenly in the groove. Verify the ring is fully seated before returning the assembly to service.
