Manufactured from 15-7 Grade 632 stainless steel and processed to an AMS-5529 specification, this ring seats in a machined groove on a 3\/8-inch shaft, providing a reliable axial stop without the need for threading or welding. The ring measures 0.025 inches in thickness with a groove width of 0.029 inches and a groove diameter of 0.352 inches. Its passivated finish enhances corrosion resistance, making it suitable for environments where standard carbon steel hardware would degrade. Machinists, maintenance technicians, and mechanical assemblers working in HVAC, fluid handling, or industrial equipment applications install this type of ring using standard retaining ring pliers.\u003c\/p\u003e\u003cp\u003eThis external retaining ring is used in applications requiring a compact, corrosion-resistant shaft stop on 3\/8-inch diameter shafts. Typical install scenarios include motor shaft assemblies, pump components, valve actuators, and precision mechanical subassemblies found in commercial and industrial equipment. The passivated stainless steel construction makes it appropriate for wet, chemically active, or high-cleanliness environments where part integrity over service life is critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e15-7 Grade 632 stainless steel construction meets AMS-5529 and UNS S15700 specifications\u003c\/li\u003e\n\u003cli\u003ePassivated finish provides enhanced corrosion resistance for harsh or wet service environments\u003c\/li\u003e\n\u003cli\u003eHardness rated 69.5-73 HRC for high load-bearing capability in shaft retention applications\u003c\/li\u003e\n\u003cli\u003eGroove diameter of 0.352 inches with tolerance of -0.002 to 0.002 inches for precise fitment\u003c\/li\u003e\n\u003cli\u003eRing thickness of 0.025 inches and groove width of 0.029 inches for low-profile axial retention\u003c\/li\u003e\n\u003cli\u003eMeets Military Specification MS 16624-4037 and ISO 13485:2015 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on 3\/8-inch diameter shafts (9.53 mm) with a groove diameter of 0.352 inches.

Ensure the shaft groove is clean, free of burrs, and within the specified groove width and depth tolerances before seating the ring. Depower any rotating or pressurized equipment fully before servicing components retained by this ring. A deformed or improperly seated ring should be replaced rather than reused.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches \/ 9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Diameter\u003c\/strong\u003e: 0.352 inches (8.94 mm), tolerance -0.002 to 0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Diameter\u003c\/strong\u003e: 0.338 inches (8.59 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Outside Diameter\u003c\/strong\u003e: 0.61 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Width\u003c\/strong\u003e: 0.029 inches (0.74 mm), tolerance 0.000 to 0.003 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Depth\u003c\/strong\u003e: 0.012 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Thickness\u003c\/strong\u003e: 0.025 inches (0.64 mm), tolerance -0.002 to 0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 15-7 Grade 632 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 69.5-73 HRC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Passivated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: AMS-5529, UNS S15700, ISO 13485:2015, MS 16624-4037\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0004 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ROTOR CLIP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SH-37SS MPS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51693068845362,"sku":"SH-37SS MPS","price":21290.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bdd7e3d5f2af4164db9d9a73af6439b3_6eaef060-9ead-4c5d-be5a-d8fbad61ab7a.jpg?v=1788306907","url":"https:\/\/voomisupply.com\/products\/rotor-clip-sh-37ss-mps-external-retaining-ring-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
