This joint delivers up to 768 inch-pounds of torque, making it suitable for moderate-duty mechanical drive applications. With a bore depth of 7\/8 inches, an inside diameter of 3\/8 inches, an outside diameter of 3\/4 inches, and an overall length of 5-3\/8 inches, it fits into compact drive train assemblies where precise motion transfer is required. It is installed by mechanical technicians and maintenance professionals working on industrial and HVAC equipment drive systems.\u003c\/p\u003e\u003cp\u003eThe 68514417015 is suited for applications requiring a double universal joint configuration, which allows for greater angular offset compared to a single joint design. Typical installations include fan drive assemblies, actuator linkages, and light industrial machinery where shaft misalignment must be accommodated without sacrificing torque transfer. The DD-type configuration provides two pivot points in series, reducing velocity variation across the joint at moderate operating angles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDD-type double universal joint design accommodates greater angular misalignment than single joint configurations\u003c\/li\u003e\n\u003cli\u003eRated torque of 768 inch-pounds for moderate-duty mechanical drive applications\u003c\/li\u003e\n\u003cli\u003e7\/8 inch bore depth with 3\/8 inch inside diameter and 3\/4 inch outside diameter\u003c\/li\u003e\n\u003cli\u003eOverall length of 5-3\/8 inches for compact drive train fitment\u003c\/li\u003e\n\u003cli\u003eSingle-piece package quantity, sold individually\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit DD-type double universal joint for mechanical drive assemblies requiring a 3\/8 inch inside diameter shaft connection and up to 768 inch-pounds of torque capacity.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanical technician familiar with rotating drive components. Disengage and lock out all power to the drive system before removing or installing the joint. Verify shaft alignment and operating angle fall within the joint's rated limits before finalizing installation. Inspect mating shaft surfaces for wear or damage prior to assembly to ensure proper fit and torque transfer.\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\u003eRated Torque\u003c\/strong\u003e: 768 inch-pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Depth\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 5-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.55 pounds\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: 68514417015\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51543110779186,"sku":"68514417015","price":342.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d2d974abee9c2d1f07a0e57c8f1e2af3.jpg?v=1785915710","url":"https:\/\/voomisupply.com\/products\/lovejoy-68514417015-dd-type-double-universal-joint","provider":"Voomi Supply","version":"1.0","type":"link"}
