Rotor Clip BE-50ST Pa Bowed E Retaining Ring 1/2 in

Product Description

The ROTOR CLIP BE-50ST PA is an external bowed E style retaining ring designed for use on 1/2-inch diameter shafts. The bowed profile exerts axial force against the retained component, compensating for stack-up tolerances and reducing end play without the need for additional spring elements. Manufactured from SAE 1060-1090 steel and finished with a phosphate coating for corrosion resistance, this ring is hardened to 47-52 HRC. The three-prong design allows installation and removal with standard retaining ring pliers. It is used in mechanical assemblies across HVAC equipment, pump drives, motors, and related rotating equipment.

This retaining ring is suited for light-duty to medium-duty shaft retention applications in both residential and commercial equipment. Typical installations include electric motor shafts, fan assemblies, pump impeller shafts, and small gearbox assemblies where controlled axial preload is required. The 0.396-inch groove diameter and 0.073-inch groove width define its fitment. Mechanical assemblers, equipment repair technicians, and OEM production lines are the primary users. The minimum order quantity is 100 pieces per purchase.

Installation Notes

Installation and removal must be performed using retaining ring pliers sized for external E style rings to avoid distorting the prongs or ring body. De-energize and lock out all equipment before servicing any shaft assembly containing this ring. Inspect the shaft groove for burrs or wear that could affect ring seating or retention force. Do not reuse a ring that has been overstressed, visibly deformed, or removed multiple times.
