It seats in a precision groove and provides axial retention for components such as bearings, gears, and pulleys on shafts in industrial and mechanical assemblies. Manufactured from SAE 1060-1090 steel with a cadmium finish, the ring achieves a hardness of 47-52 HRC, providing reliable holding strength in demanding applications. The three-prong E style configuration allows for tool-free or pliers-assisted installation and removal without full shaft disassembly, making it a practical choice for maintenance and repair workflows.\u003c\/p\u003e\n\u003cp\u003eThis retaining ring is suited for use in industrial machinery, power transmission assemblies, pumps, motors, and other rotating equipment where external shaft retention is required. It is commonly installed by millwrights, mechanical technicians, and maintenance professionals working on equipment that uses 1-3\/8 inch shafts. The cadmium plating provides corrosion resistance in moderate-duty environments. This part meets Military Specification MS 16633-1137 and is manufactured to ISO 13485:2015 standards, making it appropriate for applications requiring traceable, specification-compliant fasteners.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eE style external retaining ring with three prongs for side-load installation without shaft removal\u003c\/li\u003e\n  \u003cli\u003eFits 1-3\/8 inch shaft diameter with a groove diameter of 1.23 inches\u003c\/li\u003e\n  \u003cli\u003eSAE 1060-1090 steel construction hardened to 47-52 HRC for mechanical durability\u003c\/li\u003e\n  \u003cli\u003eCadmium finish provides corrosion resistance in moderate service environments\u003c\/li\u003e\n  \u003cli\u003eMeets Military Specification MS 16633-1137 and ISO 13485:2015\u003c\/li\u003e\n  \u003cli\u003eRing thickness of 0.062 inches with tight tolerance for consistent groove fit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style external retaining ring for 1-3\/8 inch diameter shafts with a groove diameter of 1.23 inches, a groove width of 0.068 inches, and a groove depth of 0.072 inches.
