Rotor Clip E-37SS Mps External E Style Retaining Ring

Product Description

The ROTOR CLIP E-37SS MPS is an external E style retaining ring designed to secure components on shafts in demanding mechanical assemblies. Manufactured from 15-7 Grade 632 stainless steel and passivated for corrosion resistance, this ring fits a 3/8 inch shaft diameter with a groove diameter of 0.303 inches. At 0.035 inches thick and hardened to 37-43 HRC, it delivers reliable retention in applications where strength and material compatibility matter. The three-prong E style design allows for tool-assisted installation and removal without full shaft disassembly, making it a practical choice for maintenance-intensive equipment. Installation professionals in industrial, aerospace, and mechanical service trades work with this ring type regularly.

This retaining ring is suited for use in rotating shaft assemblies, precision machinery, and fastened mechanical systems where space is limited and a traditional snap ring is not practical. The E style configuration is commonly found in shafts that require frequent access or field serviceability. Its stainless steel construction and AMS-5529 compliance make it appropriate for environments where corrosion resistance and documented material traceability are required, including regulated manufacturing and aerospace maintenance operations.

Compatibility

Designed as an OEM-style external E style retaining ring for 3/8 inch shafts with a groove diameter of 0.303 inches and groove width of 0.039 inches in mechanical assemblies requiring AMS-5529 or MS 16633-4037 compliant components.

Installation Notes

Installation and removal should be performed by qualified mechanical or industrial technicians using appropriate E ring pliers to avoid deforming the prongs or the ring body. Always de-energize and lock out equipment before servicing shaft assemblies. Confirm groove dimensions match ring specifications before installation to prevent improper seating. Refer to applicable mechanical codes and manufacturer assembly documentation for torque and assembly sequence guidance.
