It features a rated torque capacity of 7,920 inch-pounds and a 1-3\/16 inch bore depth, making it suitable for demanding drive applications where a single universal joint would introduce unacceptable velocity variation. The double-joint configuration cancels angular velocity fluctuations, delivering smoother power transfer. With an overall length of 8-1\/2 inches and a package weight of 3.6 pounds, this is a solid, production-grade component intended for installation by mechanical technicians and drive system specialists.\u003c\/p\u003e\u003cp\u003eThis double universal joint is used in industrial drive shaft assemblies, mechanical power transmission systems, and equipment requiring flexible shaft couplings across angular offsets. The 3\/4 inch inside diameter and 1-1\/2 inch outside diameter yoke dimensions make it compatible with standard shaft and bore configurations encountered in light-to-medium industrial machinery. It is typically installed in conveyor drives, pump drives, and similar rotating equipment where shaft alignment cannot be held perfectly concentric.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDD-type double universal joint design cancels angular velocity variation for smoother torque delivery\u003c\/li\u003e\n\u003cli\u003e7,920 inch-pounds rated torque capacity suitable for medium-duty drive applications\u003c\/li\u003e\n\u003cli\u003e1-3\/16 inch bore depth accommodates standard shaft sizing\u003c\/li\u003e\n\u003cli\u003e3\/4 inch inside diameter by 1-1\/2 inch outside diameter yoke interface\u003c\/li\u003e\n\u003cli\u003e8-1\/2 inch overall length fits standard drive shaft configurations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit component for industrial drive shaft assemblies requiring a DD-type double universal joint with 3\/4 inch inside and 1-1\/2 inch outside diameter yoke dimensions and a 7,920 inch-pound torque rating.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanical technician familiar with rotating drive components. Disconnect and lock out all power sources before removing the existing joint or installing the replacement. Ensure shaft ends are clean, properly sized, and free of burrs before fitting the joint. Verify angular alignment is within the joint's rated operating angle range before returning the system to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eJoint Type\u003c\/strong\u003e: DD-Type Double Universal Joint\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTorque Rating\u003c\/strong\u003e: 7,920 inch-pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Depth\u003c\/strong\u003e: 1-3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 8-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.6 pounds\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: 68514417050\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51542865412402,"sku":"68514417050","price":716.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bf1801e1c01c57fec694c00dbf785f93_f0dca882-5277-40e5-ac4a-f2a099eba620.jpg?v=1785909338","url":"https:\/\/voomisupply.com\/products\/lovejoy-68514417050-dd-type-double-universal-joint","provider":"Voomi Supply","version":"1.0","type":"link"}
