Rotor Clip RE-25ST Pa Retaining Ring 1/4 Inch Shaft

Product Description

The ROTOR CLIP RE-25ST PA is an external reinforced E style retaining ring designed to secure components on shafts without the need for grooved tooling on the retained part. Manufactured from SAE 1060-1090 steel with a phosphate finish for corrosion resistance, this ring fits a 0.25 inch shaft diameter with a 0.21 inch groove diameter. The three-prong reinforced E style design provides reliable axial retention and resists lug distortion under load. It measures 0.025 inches in ring thickness and carries a free outside diameter of 0.516 inches. Installation and removal are performed with standard retaining ring pliers. This part is used by maintenance technicians, mechanical assemblers, and MRO professionals across industrial and commercial applications.

This retaining ring is suited for light-duty shaft assemblies in industrial machinery, power transmission equipment, motors, pumps, and similar mechanical assemblies requiring external axial retention on a 1/4 inch shaft. The reinforced E style is particularly common in applications where a standard E ring would be prone to lug damage or rollout under side loading. The phosphate finish provides moderate corrosion protection suitable for dry or lightly lubricated environments. Minimum order quantity is 100 pieces per order.

Compatibility

Designed as an OEM-style external retaining ring for 1/4 inch shaft diameter applications across industrial machinery, motors, pumps, and mechanical assemblies requiring E style axial retention.

Installation Notes

Installation and removal require retaining ring pliers sized for E style rings. Always power down or de-energize the equipment and relieve any mechanical load on the shaft assembly before servicing. Confirm groove diameter and groove width tolerances are within specification before installation to prevent ring rollout or seat failure. Observe applicable machinery safety standards and facility lockout-tagout procedures during service.
