It features a trapezoidal wire shape that allows for a higher load capacity in a compact envelope compared to round-wire springs. With a free length of 1.5 inches, a maximum deflection of 0.75 inches, and a maximum deflection load of 81 pounds, this spring delivers consistent, predictable force across its working range. The spring rate is 108 pounds per inch. It is manufactured from chromium alloy steel for fatigue resistance under cyclic loading conditions.\u003c\/p\u003e\n\u003cp\u003eThis die spring is suited for use in metal stamping tooling, injection mold components, and industrial press applications where repeatable spring force is required. The blue color coding indicates medium-duty rating per standard die spring classification. It fits a 0.625-inch hole diameter and a 0.34375-inch rod diameter, making it a direct fit for tooling designed to those bore and pin dimensions. Fabricators, tool and die makers, and maintenance technicians working on stamping or forming equipment are the primary installers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTrapezoidal wire shape provides higher load capacity relative to free length compared to round-wire die springs\u003c\/li\u003e\n  \u003cli\u003eMedium-duty rating, color-coded blue for quick identification during tooling assembly\u003c\/li\u003e\n  \u003cli\u003eSpring rate of 108 pounds per inch for consistent, predictable force output\u003c\/li\u003e\n  \u003cli\u003eMaximum deflection load of 81 pounds at 0.75 inches of travel\u003c\/li\u003e\n  \u003cli\u003eChromium alloy steel construction for fatigue resistance in high-cycle applications\u003c\/li\u003e\n  \u003cli\u003eManufactured under ISO 9001:2008 and ISO\/TS 16949:2009 certified quality systems, TUV Rheinland registered\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard medium-duty die spring replacement for tooling with a 0.625-inch hole diameter and an 0.34375-inch rod diameter, with a 1.5-inch free length requirement.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDie springs are installed by tool and die makers or maintenance technicians during tooling builds or planned maintenance intervals. Before replacing a die spring, de-energize and lock out the press per applicable machine safety procedures. Inspect the mating bore and rod for wear or damage before installing a new spring. Do not exceed the rated maximum deflection of 0.75 inches, as operating beyond this value will accelerate fatigue and reduce service life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRod Diameter\u003c\/strong\u003e: 0.34375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Deflection\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Deflection Load\u003c\/strong\u003e: 81 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 108 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\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\u003eColor Code\u003c\/strong\u003e: Blue\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 103-306\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASSOCIATED SPRING","offers":[{"title":"Default Title","offer_id":51978996318514,"sku":"103-306","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/261f1d0d82c40f1c8d1d7f5a2d6464b2.jpg?v=1789980545","url":"https:\/\/voomisupply.com\/products\/associated-spring-raymond-103-306-die-spring-medium-duty-blue","provider":"Voomi Supply","version":"1.0","type":"link"}
