It seats in a precision groove and holds components axially on the shaft without requiring threading, welding, or additional fasteners. Manufactured from 1060\/1090 spring steel with a phosphate and oil finish, it achieves a hardness of 44-51 HRC for reliable retention under dynamic and static loads. The ring is produced to DIN 471 and SAE 1060-1090 standards, making it suitable for industrial assemblies, mechanical drives, and OEM equipment builds. Machinists, maintenance technicians, and mechanical assemblers typically install this part.\u003c\/p\u003e\n\u003cp\u003eThis external retaining ring fits 20 mm shafts and is used in a wide range of mechanical assemblies including gearboxes, motors, pumps, and actuators where positive axial retention is required. The phosphate and oil surface treatment provides a base level of corrosion resistance and aids in lubrication during installation. It is sized to a 19 mm nominal groove diameter with a groove width of 1.30 mm and a groove depth of 0.50 mm, making it appropriate for both OEM production and MRO replacement applications in industrial settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eShaft diameter: 20 mm; groove diameter: 19 mm nominal\u003c\/li\u003e\n  \u003cli\u003e1060\/1090 spring steel construction with 44-51 HRC hardness rating\u003c\/li\u003e\n  \u003cli\u003ePhosphate and oil finish for corrosion resistance and installation lubrication\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 471 and SAE 1060-1090 fastener standards\u003c\/li\u003e\n  \u003cli\u003eRing thickness of 1.20 mm with a tolerance of -0.0600 mm for consistent fit\u003c\/li\u003e\n  \u003cli\u003eGroove width of 1.30 mm and groove depth of 0.50 mm for secure seating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style external retaining ring for 20 mm shafts conforming to DIN 471 groove specifications in industrial mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires appropriately sized external retaining ring pliers to compress and seat the ring into the shaft groove without distorting the ring or damaging the groove walls. Power down and de-energize any equipment before servicing components on the shaft. Inspect the groove for burrs or damage prior to installation, as groove condition directly affects retention capacity. Follow applicable machinery safety standards and manufacturer assembly documentation during installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Diameter\u003c\/strong\u003e: 20 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Diameter (Nominal)\u003c\/strong\u003e: 19 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Diameter Tolerance\u003c\/strong\u003e: -0.1300 to 0.1300 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Diameter\u003c\/strong\u003e: 18.50 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Diameter Tolerance\u003c\/strong\u003e: -0.4200 to 0.1300 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 18.50 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Thickness\u003c\/strong\u003e: 1.20 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Thickness Tolerance\u003c\/strong\u003e: -0.0600 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Width\u003c\/strong\u003e: 1.30 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Depth\u003c\/strong\u003e: 0.50 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Spring Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 1060\/1090\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 44-51 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Phosphate and Oil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN 471, SAE 1060-1090, ISO 13485:2015\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31163202\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: DSH-20ST PDB100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51697519821106,"sku":"DSH-20ST PDB100","price":1960.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/adea8879f090fff1e5aab60a4b5d7532.jpg?v=1788352432","url":"https:\/\/voomisupply.com\/products\/rotor-clip-dsh-20st-pdb100-external-retaining-ring-20mm","provider":"Voomi Supply","version":"1.0","type":"link"}
