Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers a spring rate of 320 pounds per inch and handles a maximum deflection load of 156 pounds at 0.5 inches of maximum deflection. The blue color coding identifies it as a medium-duty rating per standard die spring classification. Licensed HVAC techs, tool-and-die machinists, and industrial maintenance technicians working with press tooling or fixture applications install this spring type routinely.\u003c\/p\u003e\u003cp\u003eThis spring fits applications requiring a 0.75-inch hole diameter and a 0.375-inch rod diameter with a free length of 1 inch. It is suited for use in stamping dies, injection mold assemblies, jigs, and fixture tooling where consistent, repeatable spring force is required under cyclic compression loads. The medium-duty rating makes it appropriate for moderate-load cycling in production tooling environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTrapezoidal wire shape provides higher load capacity relative to round-wire springs of equivalent size\u003c\/li\u003e\n\u003cli\u003eChromium alloy steel construction for durability under repeated compression cycles\u003c\/li\u003e\n\u003cli\u003eBlue color coding identifies medium-duty rating for fast visual identification at the tooling bench\u003c\/li\u003e\n\u003cli\u003e320 pounds per inch spring rate with 156-pound maximum deflection load at 0.5 inches deflection\u003c\/li\u003e\n\u003cli\u003eISO 9001:2008 and ISO\/TS 16949:2009 certified manufacturing; TUV Rheinland registered\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard medium-duty die spring replacement for tooling applications requiring a 0.75-inch hole diameter and 0.375-inch rod diameter with a 1-inch free length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by tooling technicians or maintenance machinists during die build or tooling maintenance. Ensure the mating die pocket diameter and guide rod diameter match the spring specifications before installation. Never exceed the published maximum deflection of 0.5 inches, as over-compression can cause permanent set or premature fatigue failure. Inspect the spring for cracking, set, or color fade at regular die maintenance intervals.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRod Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Deflection\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Deflection Load\u003c\/strong\u003e: 156 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 320 pounds per inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuty Rating\u003c\/strong\u003e: Medium-Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Shape\u003c\/strong\u003e: Trapezoidal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Chromium Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANAB Accredited; ISO 9001:2008 Certified; ISO\/TS 16949:2009 Certified; TUV Rheinland Registered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161905\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ASSOCIATED SPRING RAYMOND\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 103-404\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASSOCIATED SPRING","offers":[{"title":"Default Title","offer_id":52040093368626,"sku":"103-404","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e733ea2fc487827c5a0ed08689cb1af2.jpg?v=1790026759","url":"https:\/\/voomisupply.com\/products\/associated-spring-raymond-103-404-die-spring-blue","provider":"Voomi Supply","version":"1.0","type":"link"}
