Rotor Clip SH-118ST Zd External Retaining Ring

Product Description

The ROTOR CLIP SH-118ST ZD is an external retaining ring engineered for use on shafts with a 1-3/16 inch (1.1875 inch) shaft diameter and a groove diameter of 1.118 inches. Manufactured from SAE 1060-1090 carbon steel with a yellow zinc dichromate finish, this ring provides reliable axial retention of components on shafts in demanding mechanical assemblies. Ring thickness measures 0.05 inches, groove width is 0.056 inches, and hardness runs 47-52 HRC. It is installed by machinists, maintenance mechanics, and assembly technicians across industrial, HVAC, and equipment manufacturing applications.

This retaining ring is suited for use in rotating and stationary shaft assemblies where a compact, low-profile external clip is required. Common applications include motor shaft assemblies, pump shafts, gear assemblies, and mechanical equipment found in commercial and industrial settings. The zinc dichromate finish provides corrosion resistance for use in moderate-exposure environments. Sold individually with a minimum order quantity of 10 units.

Installation Notes

External retaining rings of this type are installed and removed using dedicated retaining ring pliers; using improper tools risks deforming the ring or damaging the shaft groove. Always relieve shaft load and de-energize any connected drive or motor before servicing shaft-mounted components. Verify groove dimensions against published tolerances before installation to ensure proper seating and axial load capacity. Follow applicable machinery safety standards and the equipment manufacturer's service documentation.
