Manufactured from spring steel with a phosphate finish, this ring seats into an internal groove to retain components on a shaft or within a housing. The ring measures 1.75mm thick and features a free outside diameter of 43.5mm, making it suitable for standard 40mm bore assemblies. Installation requires a standard internal snap ring plier set. Machinists, MRO technicians, and mechanical assemblers typically install this style of retaining ring in bearing housings, gearboxes, pumps, and rotating assemblies.\u003c\/p\u003e\u003cp\u003eThis internal snap retaining ring is used in 40mm bore housings across a wide range of industrial and mechanical applications. Common install scenarios include bearing retention in electric motors, pump housings, gearbox assemblies, and precision mechanical components where a reliable, low-profile groove-seated retainer is required. The phosphate finish provides a degree of corrosion resistance suitable for standard indoor mechanical environments. The ring conforms to ISO 13485:2016 standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMetric internal snap ring designed for 40mm nominal bore diameter\u003c\/li\u003e\n\u003cli\u003eSpring steel construction for reliable radial retention force\u003c\/li\u003e\n\u003cli\u003ePhosphate finish for corrosion resistance in standard service environments\u003c\/li\u003e\n\u003cli\u003eGroove width of 1.85mm and groove depth of 1.25mm for precise seating\u003c\/li\u003e\n\u003cli\u003eThrust load capacity of 27.00 kN at the groove and 44.6 kN at the ring\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 13485:2016 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 40mm nominal bore housings requiring a metric internal snap retaining ring with a 1.85mm groove width and 1.25mm groove depth.

Ensure the housing bore and groove are free of debris and burrs before seating the ring. Confirm groove diameter tolerance of 0.25mm and ring thickness tolerance of minus 0.06mm are within acceptable range for the application before assembly. Always follow applicable machinery safety and lockout\/tagout procedures before disassembling any rotating equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Type\u003c\/strong\u003e: Internal Snap Retaining Ring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Bore Diameter\u003c\/strong\u003e: 40mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 40.58mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Outside Diameter\u003c\/strong\u003e: 43.5mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Thickness\u003c\/strong\u003e: 1.75mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Thickness Tolerance\u003c\/strong\u003e: -0.06mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Width\u003c\/strong\u003e: 1.85mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Depth\u003c\/strong\u003e: 1.25mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Diameter Tolerance\u003c\/strong\u003e: 0.25mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrust Load Capacity (Groove)\u003c\/strong\u003e: 27.00 kN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrust Load Capacity (Ring)\u003c\/strong\u003e: 44.6 kN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Spring Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Phosphate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13485:2016\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31163202\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0125 pounds\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: DHO-40ST N PD\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51709547675954,"sku":"DHO-40ST N PD","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/86dc08d4290439e1767ff54fd0f03c22_55c29512-2d30-4627-8cc2-9dd52ad65000.jpg?v=1788457826","url":"https:\/\/voomisupply.com\/products\/rotor-clip-dho-40st-n-pd-metric-internal-snap-ring-40mm","provider":"Voomi Supply","version":"1.0","type":"link"}
