Precision Brand 12935 External Retaining Ring 140 Pc

Product Description

The PRECISION BRAND 12935 is a 140-piece assortment of external retaining rings designed for use in mechanical assemblies where secure component retention is required. These rings are constructed from zinc plated spring steel, providing corrosion resistance alongside the spring tension needed to hold components firmly in place. Similar in function to housing rings, they are specifically engineered to accommodate components with large chamfers and radii, making them suitable for a wider range of shaft and bore profiles. Machinists, millwrights, and maintenance technicians will find this assortment a practical shop staple.

This assortment is well suited for industrial maintenance, mechanical repair, and assembly operations across manufacturing, HVAC equipment, and general mechanical service environments. The variety of ring sizes in the 140-piece kit reduces the need for multiple individual orders and keeps a range of sizes on hand for common repair and build tasks. The external design means these rings seat in a groove on the outside of a shaft or pin to retain an adjacent component.

Installation Notes

External retaining rings are typically installed and removed by licensed millwrights or qualified maintenance technicians using proper retaining ring pliers sized for the ring diameter. Always relieve mechanical load and de-energize equipment before servicing any assembly containing retaining rings. Inspect the shaft groove for wear or damage before seating a new ring. Do not over-expand the ring during installation, as this can compromise its retention force.
