Rated at 5,220 inch-pounds of torque, it features a 1-1\/16 inch bore depth, a 5\/8 inch inside diameter, a 1-1\/4 inch outside diameter, and an overall length of 7-1\/2 inches. The double-joint configuration allows for greater angular deflection than a single universal joint while maintaining smooth torque transfer. This component is typically installed by millwrights, mechanical contractors, or industrial maintenance technicians working on power transmission equipment.\u003c\/p\u003e\u003cp\u003eThis double universal joint is suited for industrial and commercial mechanical drive applications where shaft misalignment cannot be fully corrected by other coupling methods. The DD-type design accommodates compound angular misalignment across two joint axes, making it appropriate for use in conveyor systems, machine tool drives, agricultural equipment, and similar rotating machinery. Its 7-1\/2 inch overall length provides the span needed for installations requiring offset shaft connections.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDD-type double universal joint configuration for compound angular misalignment compensation\u003c\/li\u003e\n\u003cli\u003e5,220 inch-pound torque rating for demanding power transmission applications\u003c\/li\u003e\n\u003cli\u003e1-1\/16 inch bore depth accommodates common shaft sizing\u003c\/li\u003e\n\u003cli\u003e5\/8 inch inside diameter by 1-1\/4 inch outside diameter cross section\u003c\/li\u003e\n\u003cli\u003e7-1\/2 inch overall length for offset shaft installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct installation component for mechanical power transmission assemblies requiring a DD-type double universal joint with a 5,220 inch-pound torque rating and 1-1\/16 inch bore depth.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified millwright or mechanical technician. De-energize and lockout all connected machinery before beginning removal or installation of the joint. Ensure shaft and bore dimensions are verified prior to installation to confirm proper fit and avoid binding under load. Follow applicable ANSI and OSHA machine guarding requirements when reinstalling drive components.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTorque Rating\u003c\/strong\u003e: 5,220 inch-pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Depth\u003c\/strong\u003e: 1-1\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 7-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.18 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJoint Type\u003c\/strong\u003e: DD-Type Double Universal Joint\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LOVEJOY\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 68514417120\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51542681682226,"sku":"68514417120","price":376.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/463114ee656e935bada1f2696352104f_04111a33-54a8-4bf5-ad64-87d62e6ddd1c.jpg?v=1785904377","url":"https:\/\/voomisupply.com\/products\/lovejoy-68514417120-dd-type-double-universal-joint","provider":"Voomi Supply","version":"1.0","type":"link"}
