Rotor Clip BE-37ST Pa Bowed E Retaining Ring 3/8 in

Product Description

The ROTOR CLIP BE-37ST PA is an external bowed E style retaining ring designed for securing components on shafts in a wide range of mechanical assemblies. Manufactured from SAE 1060-1090 steel (UNS G10600-G10900) and finished with a phosphate coating, this ring delivers solid corrosion resistance and hardness in the 47-52 HRC range. It seats in an external groove on a 3/8-inch shaft, with a groove diameter of 0.303 inches and a ring thickness of 0.035 inches. The three-prong bowed E design allows for tool-free installation by hand in many applications, making it a practical choice for high-volume assembly operations.

This retaining ring is suited for use in light machinery, motors, pumps, and precision mechanical assemblies where a compact external fastener is required on a 3/8-inch shaft. The phosphate finish makes it appropriate for environments with moderate exposure to moisture or mild corrosives. It is typically installed by machinists, maintenance technicians, and assembly professionals working with inch-measurement fastener systems. The minimum order quantity is 100 units, making it well suited for production and repair shop stocking.

Installation Notes

Installation is performed by maintenance technicians or assembly professionals as part of shaft and bearing assembly work. Ensure the shaft groove is free of burrs and debris before seating the ring. Power down and de-energize any associated equipment fully before servicing components that use this retaining ring. Verify groove dimensions against the ring tolerances prior to installation to ensure proper retention and avoid ring dislodgement under load.
