Rotor Clip SH-75ST Pa B100 External Snap Retaining Ring

Product Description

The ROTOR CLIP SH-75ST PA B100 is an external snap retaining ring designed to secure components on a 3/4 inch (0.750 inch) shaft. It seats in a machined groove with a groove diameter of 0.704 inches and a groove width of 0.046 inches, providing axial retention without the need for threads or pins. Manufactured from SAE 1060-1090 spring steel with a phosphate finish, the ring delivers consistent spring force and corrosion resistance in demanding environments. Hardness is rated at 66-71 HRC. This ring is installed and removed by machinists, maintenance technicians, and assembly professionals working on rotating shafts, gearboxes, and drive assemblies.

This external retaining ring is suited for industrial assemblies requiring reliable axial retention on 0.750 inch shafts. Typical applications include electric motor shafts, pump assemblies, gearbox components, and mechanical drive systems where a compact, low-profile ring is required. The phosphate finish provides mild corrosion protection appropriate for indoor mechanical or light industrial environments. It is sold in a minimum order quantity of 100 pieces, making it practical for production line use, MRO stocking, and field service kits.

Installation Notes

External snap rings of this type are installed and removed using external snap ring pliers; never pry or drive the ring with screwdrivers or chisels, as this can deform the ring or damage the groove. Ensure the shaft groove is clean and within tolerance before seating the ring. Depower any rotating equipment and follow applicable OSHA lockout/tagout procedures before servicing shaft components. Inspect the ring for deformation or cracking before reuse — do not reinstall a ring that has been over-expanded.
