Rotor Clip HO-150SS B100 Internal Snap Retaining Ring

Product Description

The ROTOR CLIP HO-150SS B100 is a stainless steel internal snap retaining ring designed to seat in a machined groove inside a bore and hold components axially in place. Built from 15-7 Grade 632 stainless steel, it provides strong corrosion resistance and high hardness in the Rockwell C 44-51 range. The ring fits a 1.5-inch bore diameter, with a free outside diameter of 1.66 inches and a ring thickness of 0.05 inches. Maintenance technicians, millwrights, and mechanical assemblers use this type of ring in shafts, housings, and precision assemblies where a reliable internal retaining solution is required.

This internal retaining ring is suited for use in industrial, HVAC, pump, and mechanical equipment assemblies where an internal groove retains a shaft, bearing, or component inside a bore. It is appropriate for both original equipment assembly and maintenance repair applications. The groove accepts a width of 0.056 inches and a depth of 0.047 inches, making it compatible with standard internal groove specifications at the 1.5-inch bore size. This ring is sold individually (package quantity of 1).

Installation Notes

Installation requires snap ring pliers sized for internal retaining rings — always use the correct tool to avoid distorting the ring during installation or removal. Shut down and de-energize any equipment before servicing assemblies that contain retaining rings. Verify bore groove dimensions match the ring specifications before installation, as an undersized or oversized groove will compromise load capacity. Inspect the ring and groove for burrs or damage before assembly.
