Rotor Clip HO-175SS B100 Internal Snap Retaining Ring

Product Description

The ROTOR CLIP HO-175SS B100 is a stainless steel internal snap retaining ring designed to secure components within a bored housing by seating in a machined groove. Built from 15-7 Grade 632 stainless steel with a Rockwell C hardness of 44-51, it provides strong axial retention in corrosive or high-stress environments. The ring measures 1-3/4 inches in bore diameter with a free outer diameter of 1.942 inches and a ring thickness of 0.062 inches. Groove width is 0.068 inches and groove depth is 0.054 inches. This type of fastener is installed by machinists, maintenance technicians, and assemblers working on precision mechanical assemblies.

Internal snap retaining rings like the HO-175SS B100 are used in applications where a shaft-mounted component must be axially restrained inside a housing bore. Common installations include gearboxes, pumps, motors, and hydraulic cylinders in both industrial and commercial settings. The stainless steel construction makes it well suited for wet, chemically exposed, or washdown environments where carbon steel rings would corrode. The ring meets AMS-5529 and ISO 13485:2016 standards, confirming dimensional and material consistency for critical applications.

Compatibility

Designed as an OEM-style internal snap retaining ring for use in housings with a 1-3/4 inch bore diameter and a machined groove dimensioned to accept a 0.068 inch wide by 0.054 inch deep groove profile.

Installation Notes

Installation and removal of internal snap retaining rings requires snap ring pliers sized for internal rings; using improper tools can distort the ring or damage the groove. Ensure the housing bore and groove are clean and free of burrs before installation. Verify groove dimensions match the ring specifications before seating the ring to avoid under-retention or ring failure under load. Always relieve any system pressure or load from the assembly before servicing components retained by snap rings.
