Rotor Clip HO-50ST Mcd Internal Snap Retaining Ring

Product Description

The ROTOR CLIP HO-50ST MCD is a steel internal snap retaining ring designed for use in bores with a 0.5-inch diameter. It functions as a mechanical fastener that seats into a machined groove inside a bore, retaining components axially without the need for threads or adhesives. The ring is manufactured from 1060/1090 carbon steel with a cadmium finish and meets multiple Military Specifications, making it suitable for demanding applications where tolerance control and load capacity are critical. Ring thickness is 0.035 inches with a groove width of 0.039 inches. Machinists, maintenance technicians, and assembly professionals working on precision mechanical assemblies commonly install this part.

This internal retaining ring is used in applications where a component must be positively retained inside a bore. Typical installation scenarios include industrial machinery, military and defense equipment, hydraulic components, and general mechanical assemblies requiring a MIL-Spec fastener. The cadmium finish provides corrosion resistance in environments where bare steel would be inadequate. With thrust load capacity rated at 2,010 pounds at the ring safety factor and 510 pounds at the groove safety factor, this ring is appropriate for moderate to high axial load retention within its bore class.

Key Features

Compatibility

Designed as an OEM-style internal retaining ring for use in precision-machined bores requiring MIL-Spec snap ring fasteners with a 0.5-inch bore diameter and corresponding groove geometry.

Installation Notes

Installation is performed by machinists or mechanical assembly technicians using internal snap ring pliers sized for the bore diameter. Ensure the groove dimensions match the ring specifications before installation — groove width tolerance is 0.000 to 0.003 inches and groove diameter tolerance is -0.002 to 0.002 inches. Do not over-expand the ring during installation, as permanent deformation will compromise retention load capacity. Cadmium-coated parts should be handled in accordance with applicable workplace safety guidelines for cadmium exposure.
