Rotor Clip HO-250ST Zd Internal Snap Retaining Ring

Product Description

The ROTOR CLIP HO-250ST ZD is a heavy-duty internal snap retaining ring designed to secure components within a bored housing by seating in a precision-machined groove. Manufactured from 1060/1090 spring steel with a zinc finish, this ring delivers reliable axial retention in high-load applications. The ring measures 0.078 inches thick with a free outer diameter of 2.78 inches and fits a 2.5-inch bore. Groove width is 0.086 inches with a groove depth of 0.074 inches. Hardness is rated at Rockwell C 47-52. Licensed HVAC technicians, millwrights, and mechanical assemblers rely on this style of ring for consistent, repeatable retention without fasteners.

This internal retaining ring is suited for use in rotating assemblies, gearboxes, pump housings, motor end bells, and similar bore-mounted applications where axial component retention is required. The zinc finish provides baseline corrosion resistance for indoor and light-duty industrial environments. Its spring steel construction allows the ring to flex during installation and return to a tight seated position in the groove, maintaining consistent thrust load capacity across the service life of the assembly.

Installation Notes

Internal snap rings of this type are installed by a qualified mechanic or assembler using internal snap ring pliers sized for the bore diameter. Always power down and de-energize any equipment before disassembling housings or bearing retainer areas. Inspect the groove for burrs or debris before seating the ring, and confirm the ring is fully seated in the groove before returning the assembly to service. Follow applicable ANSI and OEM assembly specifications for the host equipment.
