It seats into a precision-machined external groove to axially retain components on a shaft without requiring a threaded fastener or snap groove machined into a bore. Manufactured from 15-7 Grade 632 stainless steel and passivated to AMS-5529 and UNS S15700 standards, this ring delivers corrosion resistance and high hardness (37-43 HRC) suitable for demanding mechanical assemblies. The three-prong E style configuration allows installation and removal with standard retaining ring pliers. Licensed HVAC, plumbing, and industrial equipment technicians regularly use these rings in pump shafts, fan assemblies, and precision rotating components.\u003c\/p\u003e\n\u003cp\u003eThis retaining ring is suited for shafts nominally 1\/2 inch (12.70 mm) in diameter where an external groove has been machined to a groove diameter of 0.396 inches with a groove width of 0.046 inches and a groove depth of 0.052 inches. The passivated finish makes it appropriate for wet, high-humidity, or chemically exposed environments common in HVAC, pool equipment, and fluid-handling applications. It meets military specification MS 16633-4050 and ISO 13485.2015, making it acceptable for applications requiring documented material traceability.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExternal E style three-prong design for tool-assisted installation and removal on 1\/2 inch shafts\u003c\/li\u003e\n  \u003cli\u003e15-7 Grade 632 stainless steel with passivated finish for corrosion resistance in wet or chemical environments\u003c\/li\u003e\n  \u003cli\u003eHardness of 37-43 HRC for reliable axial retention under mechanical load\u003c\/li\u003e\n  \u003cli\u003eMeets AMS-5529, UNS S15700, MS 16633-4050, and ISO 13485.2015 specifications for traceability-sensitive assemblies\u003c\/li\u003e\n  \u003cli\u003eRing thickness of 0.042 inches with tight tolerance (+\/-0.002 inches) for consistent groove fit\u003c\/li\u003e\n  \u003cli\u003eGroove width tolerance of 0.000 to 0.003 inches and groove diameter tolerance of 0.000 to 0.003 inches for precise fitment\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\/2 inch shafts with a machined external groove diameter of 0.396 inches, groove width of 0.046 inches, and groove depth of 0.052 inches per the ROTOR CLIP E-50SS MPS specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and removal require E style retaining ring pliers sized for this ring; using incorrect tooling risks deforming the prongs or the groove. De-energize and lock out all rotating machinery before servicing shaft components. Verify groove dimensions match the specified tolerances before installing to prevent ring walk-out under load.
