Rotor Clip E-18ST Pa B100 External E Retaining Ring

Product Description

The ROTOR CLIP E-18ST PA B100 is an external E style retaining ring designed to secure components on a 3/16-inch shaft. Manufactured from SAE 1060-1090 steel with a phosphate finish, this ring provides reliable axial retention in compact assemblies. The three-prong E style design allows for fast tool-free installation and removal, making it a practical choice for high-volume assembly operations. It fits a groove diameter of 0.147 inches and carries a ring thickness of 0.025 inches, giving it a low-profile footprint suited for tight clearance applications. Machinists, maintenance technicians, and assembly professionals working in industrial, HVAC, or mechanical service environments regularly specify this part.

This retaining ring is used in applications where a small-diameter external groove retainer is required on a 3/16-inch shaft. Common use cases include motor shaft retention, linkage assemblies, pump components, and light mechanical assemblies found in residential and commercial HVAC equipment, plumbing systems, and general industrial machinery. The phosphate finish provides a baseline level of corrosion resistance suitable for indoor and protected environments. This part is sold with a minimum order quantity of 100 pieces.

Compatibility

Designed for use on 3/16-inch diameter shafts with an external groove diameter of 0.147 inches. Suitable as a standard E style retaining ring in any mechanical assembly requiring axial component retention at this shaft size.

Installation Notes

Installation and removal of E style retaining rings is typically performed by machinists or maintenance technicians using retaining ring pliers or a flat-blade tool aligned with the prong slots. Always de-energize and lock out equipment before servicing any assembly containing this ring. Confirm groove dimensions match specifications before installation to prevent ring displacement under load. Inspect the groove for wear or damage that could compromise retention before reuse.
