Rotor Clip HO-43ST Zd Internal Snap Retaining Ring

Product Description

The ROTOR CLIP HO-43ST ZD is an internal snap retaining ring designed to secure components within a bored housing or bore. Made from 1060/1090 grade spring steel with a zinc finish, this ring seats in a machined internal groove to prevent axial movement of shafts, bearings, and other retained components. It has a 7/16 inch bore diameter, a free outer diameter of 0.482 inches, and a ring thickness of 0.025 inches. The groove it fits is 0.029 inches wide and 0.012 inches deep. Licensed mechanics, maintenance technicians, and assembly line personnel commonly install this type of ring in light mechanical assemblies.

This retaining ring is suited for use in precision mechanical assemblies where internal bore retention is required. Typical applications include small motor housings, gear assemblies, pumps, and light industrial equipment where a compact, reliable internal retainer is needed. The zinc finish provides basic corrosion resistance for indoor and light-duty environments. The ring meets SAE 1060-1090, UNS G10600-G10900, and ISO 13485:2016 standards, making it appropriate for quality-controlled manufacturing and service environments.

Compatibility

Designed as an OEM-style internal snap retaining ring for bores with a 7/16 inch diameter, suitable for use in mechanical assemblies requiring a 0.029 inch wide by 0.012 inch deep internal groove.

Installation Notes

Installation of internal snap rings requires an internal snap ring plier set sized appropriately for the ring diameter. Power down and de-energize any equipment before servicing components retained by this ring. Confirm groove dimensions match ring specifications before installation to avoid improper seating. Do not reuse a snap ring that has been removed, as the spring tension may be compromised.
