Rotor Clip HO-50ST Zd Internal Snap Retaining Ring

Product Description

The ROTOR CLIP HO-50ST ZD is an internal snap retaining ring designed to secure components within a bored housing by seating in a machined groove. Made from 1060/1090 grade spring steel with a zinc finish, this ring fits a 0.500 inch bore diameter and provides reliable axial retention in assemblies subject to thrust loads. The ring measures 0.035 inches thick and seats in a groove 0.039 inches wide and 0.015 inches deep. Thrust load capacity is rated at 2,010 pounds by ring safety factor and 510 pounds by groove safety factor, making it suitable for moderate-load industrial and mechanical applications. Machinists, maintenance technicians, and assembly professionals install this type of retaining ring as a standard fastening element.

This internal retaining ring is used in bored housings across a range of mechanical assemblies including pumps, gearboxes, motors, and general industrial equipment. It is sized for a 0.500 inch bore with a free outer diameter of 0.548 inches. The zinc finish provides basic corrosion resistance in standard service environments. Typical applications include shaft and bearing retention in both light commercial and industrial equipment where a compact, groove-seated fastener is required. This part is sold individually but requires a minimum order quantity of 100 units.

Key Features

Compatibility

Designed as a standard internal snap retaining ring for use in 0.500 inch bore diameter housings machined to accept a groove 0.039 inches wide and 0.015 inches deep.

Installation Notes

Internal snap retaining rings are installed by machinists or mechanical technicians using internal snap ring pliers sized for the bore diameter. Power down and de-energize all equipment before servicing any assembly containing retaining rings. Verify that the housing groove dimensions match the ring specifications before installation to avoid ring ejection under load. Do not reuse retaining rings that have been removed, as deformation during removal compromises retention force.
