Built from chromium alloy steel with a trapezoidal wire profile, it delivers a spring rate of 200 pounds per inch and handles a maximum deflection load of 150 pounds. The blue color coding identifies it as a medium-duty spring per standard die spring classifications. Licensed tradespeople and tooling technicians working in metal fabrication and press tooling will find this spring suitable for demanding cycle applications where consistent return force is required.\u003c\/p\u003e\u003cp\u003eThis spring is suited for industrial tooling setups where controlled compression and reliable return force are critical. The 0.75-inch hole diameter and 0.375-inch rod diameter make it compatible with standard die set guided installations. With a free length of 1.5 inches and a maximum deflection of 0.75 inches, it fits compact tooling cavities common in progressive and compound die assemblies. It is installed by tooling engineers, die makers, and press maintenance technicians in manufacturing and fabrication environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTrapezoidal wire cross-section provides higher load capacity relative to round-wire springs of the same envelope size\u003c\/li\u003e\n\u003cli\u003eChromium alloy steel construction for durability under high-cycle fatigue conditions\u003c\/li\u003e\n\u003cli\u003eBlue color coding identifies medium-duty rating for quick visual classification during tooling setup\u003c\/li\u003e\n\u003cli\u003eSpring rate of 200 pounds per inch for predictable and consistent force output\u003c\/li\u003e\n\u003cli\u003eMaximum deflection load of 150 pounds with 0.75 inches maximum deflection travel\u003c\/li\u003e\n\u003cli\u003eManufactured under ISO 9001:2008 and ISO\/TS 16949:2009 certified quality systems with TUV Rheinland registration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit die spring for standard guided die sets requiring a 0.75-inch hole diameter and 0.375-inch rod diameter with a 1.5-inch free length in medium-duty applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDie springs are installed by qualified tooling technicians and die makers. Always relieve press tonnage and lock out the press ram before servicing or replacing springs in a die set. Inspect the guide pins and bushings for wear before installing a new spring, as misalignment accelerates fatigue failure. Do not exceed the published maximum deflection of 0.75 inches, as over-compression will reduce spring service life.\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: 1.5 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: 150 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 200 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\u003eColor\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: 0.1 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: 103-406\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASSOCIATED SPRING","offers":[{"title":"Default Title","offer_id":52048510026034,"sku":"103-406","price":16.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c2c8ed42ff3ea792f1076dcb1c624d7a.jpg?v=1790032688","url":"https:\/\/voomisupply.com\/products\/associated-spring-raymond-103-406-die-spring-medium-duty-blue","provider":"Voomi Supply","version":"1.0","type":"link"}
