It features a trapezoidal wire shape wound from chromium alloy steel, giving it a higher load capacity in a compact profile compared to round-wire springs of the same outer diameter. The spring has a 3\/4 inch hole diameter, a 3\/8 inch rod diameter, and a 12 inch free length. At maximum deflection of 5.2 inches, it delivers a load of 190 pounds. The spring rate is 37 pounds per inch. The blue color coding identifies it as medium-duty per ISO and NAAMS standards. Installation is handled by tool and die makers, machinists, and press maintenance technicians.\u003c\/p\u003e\u003cp\u003eThis die spring is suited for medium-duty press tooling, injection mold assemblies, stripper plates, and similar industrial spring applications where consistent, repeatable force is required over high cycle counts. The 3\/8 inch rod diameter guides it onto standard die spring rod installations. Its 12 inch free length makes it appropriate for applications requiring longer stroke or higher total deflection within a guided die set. The blue duty rating is consistent with medium load classifications used across automotive and general industrial tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTrapezoidal wire profile delivers higher load density than equivalent round-wire die springs\u003c\/li\u003e\n\u003cli\u003eChromium alloy steel construction for fatigue resistance in cyclic press applications\u003c\/li\u003e\n\u003cli\u003eBlue color coding identifies medium-duty classification per ISO 10243 and NAAMS standards\u003c\/li\u003e\n\u003cli\u003e12 inch free length supports longer stroke tooling designs\u003c\/li\u003e\n\u003cli\u003eSpring rate of 37 pounds per inch for predictable, linear force output\u003c\/li\u003e\n\u003cli\u003eCompressed length at maximum load of 5.2 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard medium-duty die spring for guided rod installations with a 3\/8 inch rod diameter and a maximum bore of 3\/4 inch hole diameter, conforming to ISO 10243 and NAAMS dimensional standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDie springs of this type are installed and serviced by tool and die makers or press maintenance technicians. Always de-energize and lock out the press before performing any spring replacement on a die set. The spring must be properly guided over the rod and seated squarely in the pocket to prevent lateral loading and premature fatigue. Inspect the rod and pocket bore for wear or scoring before installing a replacement spring.\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: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Deflection\u003c\/strong\u003e: 5.2 inches (132.08 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTravel To Solid Load\u003c\/strong\u003e: 5.189 inches (131.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Deflection Load\u003c\/strong\u003e: 190 pounds (845.50 N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 37 pounds per inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompressed Length At Maximum Load\u003c\/strong\u003e: 5.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuty Rating\u003c\/strong\u003e: Medium-Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor Code\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: 0.52 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: NAAMS, ISO 10243, ISO 9001:2015\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GIBRALTAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: DCIM20-305\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51695201648946,"sku":"DCIM20-305","price":28.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c0b146aa09490b140439781871ad3886.jpg?v=1788332467","url":"https:\/\/voomisupply.com\/products\/gibraltar-dcim20-305-die-spring-3-4-in-hole-12-in-blue","provider":"Voomi Supply","version":"1.0","type":"link"}
