Thomson Industries OPNS1000 Bearing Seal 1 Inch Open Housing

Product Description

The THOMSON INDUSTRIES OPNS1000 is a steel bearing seal designed for open external housing applications. It features a 1-inch bore diameter and measures 3/16 inch wide with a 1.567-inch outside diameter. The seal incorporates a rubber lip to maintain contact and prevent contamination ingress in rotating shaft assemblies. At 0.02 pounds, it is a lightweight precision component suited for linear motion and bearing systems. Maintenance technicians and mechanical service professionals install this seal as a direct replacement or service part in compatible Thomson bearing housings.

This seal is used in open external bearing housing configurations where shaft support and contamination control are required. It is appropriate for light-duty industrial, automation, and mechanical drive applications. The open seal design allows for lubrication access while the rubber lip provides a working barrier against dust and debris. Compatible housing types and unit designations are noted in the compatibility section below.

Installation Notes

Installation is typically performed by mechanical technicians or maintenance professionals familiar with linear motion and bearing systems. De-energize all equipment and relieve any load from the shaft assembly before removing or installing bearing seals. Use appropriate seal installation tools to press the seal evenly into the housing bore without distorting the rubber lip. Avoid using sharp tools that could nick the lip or housing seat surface.
