Rotor Clip HO-100ST Zd Internal Snap Retaining Ring

Product Description

The ROTOR CLIP HO-100ST ZD is a heavy-duty internal snap retaining ring designed to secure components within a bored housing or assembly. Manufactured from SAE 1060/1090 spring steel with a zinc finish, this ring seats into a machined internal groove to provide reliable axial retention. The bore diameter is 1 inch, and the free outer diameter measures 1.111 inches. Ring thickness is 0.042 inches, and the groove width is 0.046 inches with a depth of 0.033 inches. This part is installed by machinists, maintenance technicians, and assembly professionals working on mechanical drive, pump, or similar rotating or stationary assemblies.

This internal retaining ring is suited for use in residential and commercial mechanical assemblies where a 1-inch bore housing requires positive axial retention of a shaft component, bearing, or bushing. The zinc finish provides corrosion resistance in moderate-duty environments. With a thrust load capacity of 2,800 pounds at groove safety factor and 6,039 pounds at ring safety factor, this ring handles demanding load conditions in industrial and OEM assembly applications.

Key Features

• Internal snap ring design fits 1-inch bore diameter housings

• Zinc finish for corrosion resistance in moderate environments
• Groove safety factor thrust load capacity: 2,800 pounds
• Ring safety factor thrust load capacity: 6,039 pounds
• Meets ISO 13485:2016 and SAE 1060-1090 / UNS G10600-G10900 standards

Compatibility

Designed for use in machined housings with a 1-inch internal bore diameter and a groove width of 0.046 inches, groove depth of 0.033 inches, and groove diameter tolerance of -0.0030 to 0.0030 inches.

Installation Notes

Installation requires internal snap ring pliers sized for the bore diameter. The mating groove must be machined to the specified width, depth, and tolerance before ring installation. Always relieve system load and de-energize or isolate the assembly before servicing. Do not over-spread the ring during installation, as exceeding the elastic limit of the spring steel will compromise retention integrity.
