Rotor Clip HO-25ST Mcd Internal Snap Retaining Ring

Product Description

The ROTOR CLIP HO-25ST MCD is a steel internal snap retaining ring designed to secure components within a bored housing. With a 0.25 inch bore diameter and a free outer diameter of approximately 0.28 inches (7.11 mm), this ring installs into a precision-machined internal groove to provide axial retention without fasteners. Ring thickness measures 0.015 inches (0.38 mm) and groove width is 0.02 inches (0.51 mm). Manufactured from SAE 1060-1090 steel with a cadmium finish for corrosion protection, this ring meets multiple Military Specifications and is suited for aerospace, defense, and precision mechanical assembly applications. Licensed maintenance technicians, mechanical assemblers, and MRO professionals typically work with this component.

This retaining ring is used in internal bore applications where axial load retention is required in tight tolerances. Its cadmium finish makes it appropriate for environments where corrosion resistance is a priority. The ring carries a thrust load capacity of 190 pounds at groove safety factor and 426 pounds at ring safety factor, making it suitable for moderate-load retention tasks in precision assemblies, instrumentation housings, and military-grade mechanical systems. It is sold in a minimum order quantity of 100 units per order with individual package quantity of 1.

Installation Notes

Internal snap retaining rings of this type are installed by mechanical assemblers using internal snap ring pliers sized for the bore diameter. Always verify groove dimensions match the ring specifications before installation to avoid improper seating or ring failure under load. Ensure the housing bore groove meets the specified groove width tolerance of 0.000 to 0.002 inches and groove diameter tolerance of -0.001 to 0.001 inches. Do not reuse snap rings that have been removed, as the ring may be deformed and retention capacity compromised.
