Thomson Industries PR1000 Steel Internal Retaining Ring

Product Description

The THOMSON INDUSTRIES PR1000 is a steel push-in internal retaining ring designed to secure components within a bore or housing. With an inside diameter of 1.563 inches, this ring seats firmly into a grooved bore to retain linear bearing assemblies and related components. The push-in style allows for straightforward installation without specialty pliers in most applications. It is a single-piece hardware item intended for use by maintenance technicians, millwrights, and mechanical service professionals working on linear motion systems.

This retaining ring is specified for use with Thomson linear bearings, including the SSU-16, SUPER-16, and 162536 bearing units. It is suited for light industrial, automation, and mechanical assembly applications where a reliable internal bore retention method is required. The ring is appropriate for both OEM assembly and field replacement when an existing ring is damaged or lost during service.

Installation Notes

Installation and removal of internal retaining rings should be performed by a qualified technician using the appropriate retaining ring pliers for internal bore applications. Ensure the housing or bore groove is clean and free of debris before seating the ring. Always relieve any load or tension on the bearing assembly before servicing retaining hardware. Follow the equipment manufacturer's service documentation for torque and assembly sequence requirements.
