Made from SAE 1060-1090 stainless steel with a yellow zinc dichromate finish, it delivers corrosion resistance and a hardness rating of 37-43 HRC for reliable retention under load. The ring has a free diameter of 0.392 inches, a free outside diameter of 0.8 inches, and a ring thickness of 0.042 inches. It is installed by machinists, maintenance technicians, and assembly professionals working on shafts, spindles, and rotating assemblies across industrial and mechanical systems.\u003c\/p\u003e\u003cp\u003eThis retaining ring is suited for use in light-duty shaft assemblies where a compact, three-prong E style clip is required. Typical applications include small motor shafts, pump components, gear assemblies, and similar mechanical subassemblies requiring positive axial retention without machined threads. The zinc dichromate finish provides additional protection in environments with moderate moisture or chemical exposure. This part is sold individually but requires a minimum order quantity of 100 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eE style external design seats into a shaft groove for axial component retention\u003c\/li\u003e\n\u003cli\u003eSAE 1060-1090 stainless steel construction with 37-43 HRC hardness\u003c\/li\u003e\n\u003cli\u003eYellow zinc dichromate finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eThree-prong design for positive grip on 0.5 inch shaft diameter\u003c\/li\u003e\n\u003cli\u003eMeets SAE 1060-1090, UNS G10600-G10900, and ISO 13485:2015 standards\u003c\/li\u003e\n\u003cli\u003eGroove width of 0.046 inches with tight tolerance for precise fit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard-fit E style retaining ring for 0.5 inch shafts with a groove diameter of 0.396 inches and groove width of 0.046 inches per SAE 1060-1090 and UNS G10600-G10900 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and removal should be performed with proper external snap ring pliers sized for E style rings to avoid deforming the prongs or ring body. Power down and de-energize any rotating equipment fully before servicing shaft assemblies. Inspect the shaft groove for burrs, wear, or dimensional deviation before installing a replacement ring.
