Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a spring rate of 153.00 pounds per inch and a maximum deflection load of 507.5 pounds. The 7-inch free length and blue color coding indicate a heavy-duty load category, making it straightforward to identify and specify during tooling design or maintenance. Die and tooling technicians are the typical end users for this part.\u003c\/p\u003e\u003cp\u003eThis die spring is suited for industrial press tooling and stamping applications where repeatable load performance and dimensional consistency are critical. The 1-1\/2-inch hole diameter and 3\/4-inch rod diameter make it compatible with standard die set configurations. The trapezoidal wire form maximizes load capacity relative to the compressed height compared to round-wire alternatives, which is a practical advantage in space-constrained tooling assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eChromium alloy steel construction for high fatigue life under cyclic compression\u003c\/li\u003e\n\u003cli\u003eTrapezoidal wire cross-section increases load density compared to round wire\u003c\/li\u003e\n\u003cli\u003eBlue color coding denotes heavy-duty load category for fast visual identification\u003c\/li\u003e\n\u003cli\u003e153.00 lb\/inch spring rate for predictable, linear force output\u003c\/li\u003e\n\u003cli\u003eMaximum deflection of 3.5 inches at 507.5 pounds load\u003c\/li\u003e\n\u003cli\u003eManufactured to ISO 9001:2008 and ISO\/TS 16949:2009 certified standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard die sets and punch press tooling assemblies requiring a 1-1\/2-inch hole diameter and 3\/4-inch rod diameter die spring in the heavy-duty blue load category.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDie springs should be installed by qualified tooling or maintenance technicians familiar with press tooling safety procedures. Always de-energize and lock out the press before accessing the die set. Do not compress beyond the rated maximum deflection of 3.5 inches, as over-compression will cause permanent set and reduce service life. Inspect the spring seat and guide rod for wear or misalignment before installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRod Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Length\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Deflection\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Deflection Load\u003c\/strong\u003e: 507.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 153.00 lb\/inch\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 \/ Load Category\u003c\/strong\u003e: Blue (Heavy Duty)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.95 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\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: 103-728\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASSOCIATED SPRING","offers":[{"title":"Default Title","offer_id":51973063278898,"sku":"103-728","price":70.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8547ec548bb692ea2f7be83ce9334758.jpg?v=1789971804","url":"https:\/\/voomisupply.com\/products\/associated-spring-raymond-103-728-die-spring-blue","provider":"Voomi Supply","version":"1.0","type":"link"}
