It delivers up to 540 in\/lb of torque capacity, making it suitable for demanding mechanical drive applications. The part features an 11\/16-inch bore depth, a 5\/16-inch inside diameter boot, and a 5\/8-inch outside diameter boot. At 4-1\/2 inches overall length, it fits into compact drive train assemblies. Licensed mechanical technicians and industrial maintenance professionals are the typical installers for this type of component.\u003c\/p\u003e\u003cp\u003eThis double universal joint is used in mechanical power transmission assemblies where a single universal joint cannot accommodate the required range of angular motion. Common applications include HVAC drive shafts, industrial equipment linkages, and mechanical actuation systems where two consecutive universal joints are needed to maintain near-constant velocity output. The compact overall length of 4-1\/2 inches suits tight installation envelopes in both stationary machinery and mobile equipment drive systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDD-type double universal joint for two-plane angular misalignment compensation\u003c\/li\u003e\n\u003cli\u003e540 in\/lb torque capacity for demanding mechanical drive loads\u003c\/li\u003e\n\u003cli\u003e11\/16-inch bore depth for shaft engagement\u003c\/li\u003e\n\u003cli\u003e5\/16-inch inside diameter and 5\/8-inch outside diameter boot dimensions\u003c\/li\u003e\n\u003cli\u003e4-1\/2-inch overall length fits compact drive train spaces\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.37 pounds for easy handling and installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or upgrade universal joint for mechanical drive assemblies requiring a DD-type double universal joint with 540 in\/lb torque capacity and matching bore and boot dimensions.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanical technician. Disconnect and lock out all power sources before removing or installing any drive shaft components. Ensure shaft surfaces are clean and free of burrs before seating the joint to the specified bore depth. Do not exceed the rated torque capacity during operation, as overloading a universal joint can cause premature failure or component damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTorque Capacity\u003c\/strong\u003e: 540 in\/lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Depth\u003c\/strong\u003e: 11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoot Inside Diameter\u003c\/strong\u003e: 5\/16 inches (0.31 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoot Outside Diameter\u003c\/strong\u003e: 5\/8 inches (0.63 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.37 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJoint Type\u003c\/strong\u003e: DD-Type Double Universal Joint\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 68514417087\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51538390253874,"sku":"68514417087","price":208.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/463114ee656e935bada1f2696352104f_2f35a3dc-5ab8-4e06-a7c8-ff6e3835a074.jpg?v=1785824211","url":"https:\/\/voomisupply.com\/products\/lovejoy-68514417087-dd-type-double-universal-joint","provider":"Voomi Supply","version":"1.0","type":"link"}
