Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a maximum deflection load of 154 pounds over a maximum deflection of 0.88 inches. The blue color coding identifies it as a medium-duty unit per standard die spring classification. Licensed tool and die makers, press operators, and maintenance technicians are the primary installers of this component.\u003c\/p\u003e\u003cp\u003eThis spring is suited for use in metal stamping dies, injection mold tooling, and precision fixtures where controlled compression force is critical. The 0.75-inch hole diameter accepts a 0.375-inch rod, and the 1.75-inch free length fits common die set cavities and guide pin assemblies. It is appropriate for both light production tooling and higher-cycle industrial press applications where dimensional consistency matters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTrapezoidal wire cross-section maximizes load capacity within a compact envelope\u003c\/li\u003e\n\u003cli\u003e154-pound maximum deflection load with a spring rate of 176 pounds per inch\u003c\/li\u003e\n\u003cli\u003e0.88-inch maximum deflection from a 1.75-inch free length\u003c\/li\u003e\n\u003cli\u003eChromium alloy steel construction for durability in cyclic loading environments\u003c\/li\u003e\n\u003cli\u003eBlue color coding identifies medium-duty rating at a glance\u003c\/li\u003e\n\u003cli\u003eManufactured to ISO 9001:2008 and ISO\/TS 16949:2009 quality standards\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, 0.375-inch rod diameter, and 1.75-inch free length per ISO and ANSI die spring dimensional standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by tool and die technicians during die assembly or maintenance. Always relieve all press pressure and lock out the press before removing or replacing die springs. Inspect the mating pocket bore and guide rod for wear or damage before seating the new spring. Do not compress the spring beyond its rated maximum deflection, as over-compression causes rapid fatigue and premature failure.\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: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Deflection Load\u003c\/strong\u003e: 154 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Deflection\u003c\/strong\u003e: 0.88 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 176 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: 0.1 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: 103-407\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASSOCIATED SPRING","offers":[{"title":"Default Title","offer_id":52100091380018,"sku":"103-407","price":16.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/08ea13864c33e988c5b2fe4cac33b463.jpg?v=1790068783","url":"https:\/\/voomisupply.com\/products\/associated-spring-raymond-103-407-die-spring-medium-duty","provider":"Voomi Supply","version":"1.0","type":"link"}
