Rotor Clip HO-175ST Pa Internal Snap Retaining Ring

Product Description

The ROTOR CLIP HO-175ST PA is an internal snap retaining ring designed to seat in a machined groove inside a bore to retain shafts, pins, or assemblies axially. Manufactured from spring steel with a phosphate finish, this ring is engineered for dependable retention under significant thrust loads. It fits a 1.75-inch bore diameter and has a free outer diameter of 1.942 inches. Ring thickness is 0.062 inches with a tight tolerance of plus or minus 0.003 inches, and groove width is 0.068 inches. Machinists, maintenance technicians, and assembly professionals install this type of ring in mechanical assemblies across industrial and commercial applications.

This retaining ring is used in rotating and static assemblies where a reliable internal bore retention method is required. Typical applications include gearboxes, pumps, motors, and hydraulic components where axial retention of a shaft or bearing is necessary. The phosphate finish provides moderate corrosion resistance suitable for general industrial environments. With a hardness rating of Rockwell C 47-52, the ring resists deformation under load conditions common in heavy-duty mechanical service.

Compatibility

Designed as an OEM-style internal retaining ring for bores requiring a 1.75-inch diameter groove seat with a 0.068-inch groove width and 0.054-inch groove depth.

Installation Notes

Installation and removal of internal snap rings requires snap ring pliers sized for the bore diameter; using incorrect tooling risks ring deformation or ejection under load. Relieve all system pressure, de-energize equipment, and lock out the assembly before servicing components retained by this ring. Verify groove dimensions against the ring specifications before installation to ensure proper seating and retention. Inspect the ring for nicks or deformation before reuse, as damaged rings should be replaced.
