The ROTOR CLIP HO-50ST PA is a heavy-duty internal snap retaining ring designed to secure components within a bored housing. Manufactured from 1060/1090 spring steel with a phosphate finish, this ring seats in a precision-machined internal groove to provide positive axial retention. The ring has a 0.500-inch bore diameter, a free outer diameter of 0.548 inches, and a ring thickness of 0.035 inches. Hardness is rated at Rockwell 30N 69.5-73, giving it reliable resistance to deformation under load. Licensed HVAC, plumbing, and mechanical trades use internal retaining rings in shaft and housing assemblies wherever a removable, load-bearing stop is required.
This ring is suited for residential and light commercial mechanical assemblies where a 0.500-inch bore internal groove is present. Typical applications include pump housings, fan shaft assemblies, gear boxes, and valve bodies. The groove accepts a 0.039-inch width with a depth of 0.015 inches. With a thrust load capacity of 2,010 pounds (ring safety factor) and 510 pounds (groove safety factor), the HO-50ST PA handles demanding axial loads in compact bores. It is sold individually per package with a minimum order quantity of 100 units.
Designed as an OEM-style internal retaining ring for any housing or bore assembly requiring a 0.500-inch internal groove with a 0.039-inch groove width and 0.015-inch groove depth.
Internal snap retaining rings are installed and removed by mechanical technicians using internal snap ring pliers sized for the bore diameter. Always de-energize and depressurize the assembly before servicing components secured by retaining rings. Confirm groove dimensions match ring specifications before installation to avoid ring ejection under load. Refer to applicable ASME or OEM assembly standards for torque and preload requirements on surrounding components.
