Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a maximum deflection load of 356 pounds and a spring rate of 552 pounds per inch. The 2-inch free length compresses up to 0.65 inches at maximum deflection, with travel to solid rated at approximately 0.638 inches. The red color coding identifies it as a heavy-duty rating per industry convention. It is sized for a 0.75-inch hole diameter and a 0.375-inch rod diameter, making it straightforward to locate and seat in standard tooling bores.\u003c\/p\u003e\u003cp\u003eThis die spring is suited for industrial tooling, stamping, and metal-forming applications where repeatable, high-load compression is required. It fits into press tooling, injection mold assemblies, and fixture applications that demand consistent spring performance under cyclic loading. Maintenance technicians and tool-and-die professionals replace these springs as part of scheduled tooling maintenance or after detecting reduced spring force or coil fatigue during inspection.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHeavy-duty load rating with 356-pound maximum deflection load\u003c\/li\u003e\n\u003cli\u003eChromium alloy steel construction for durability under cyclic compression\u003c\/li\u003e\n\u003cli\u003eTrapezoidal wire shape maximizes load capacity within a compact cross-section\u003c\/li\u003e\n\u003cli\u003e0.65-inch maximum deflection with a 552 lb\/in spring rate for predictable performance\u003c\/li\u003e\n\u003cli\u003eRed color coding for fast heavy-duty identification on the tool floor\u003c\/li\u003e\n\u003cli\u003eMeets NAAMS, ISO 10243, and ISO 9001:2015 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement die spring for industrial stamping dies, press tooling, and mold assemblies requiring a 0.75-inch hole diameter, 0.375-inch rod diameter, and 2-inch free length in a heavy-duty load class.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDie spring replacement is typically performed by tool-and-die technicians or maintenance personnel with the press locked out and de-energized per LOTO procedures. Inspect the bore and rod for wear or scoring before seating the new spring, as surface damage accelerates spring fatigue. Do not exceed the rated maximum deflection during operation. Confirm the spring is fully seated and aligned on the rod before returning the tooling to service.\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: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Deflection\u003c\/strong\u003e: 0.65 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Deflection Load\u003c\/strong\u003e: 356 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 552 pounds per inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTravel to Solid Load\u003c\/strong\u003e: 0.6378 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompressed Length at Maximum Load\u003c\/strong\u003e: 0.65 inches\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\u003eDuty Rating\u003c\/strong\u003e: Heavy-Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Red\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0893 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: DCIH20-51\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51711037309234,"sku":"DCIH20-51","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9a0b89b23a5b8a375b8a4bf779399ead.jpg?v=1788473790","url":"https:\/\/voomisupply.com\/products\/gibraltar-dcih20-51-die-spring-3-4-in-red-heavy-duty","provider":"Voomi Supply","version":"1.0","type":"link"}
