It delivers a torque capacity of 15,600 in\/lb and accommodates a bore depth of 1.5 inches. The boot measures 1 inch inside diameter and 2 inches outside diameter. The overall assembly length (OAL) is 10.875 inches. This type of double universal joint is typically installed by millwrights, maintenance mechanics, or industrial tradespeople working on drive shafts, power transmission assemblies, and equipment requiring flexible coupling across angular offsets.\u003c\/p\u003e\u003cp\u003eThe 68514417056 suits applications where a single universal joint would produce velocity variation at the output shaft. A DD-type double joint cancels that variation, making it well suited for industrial machinery, agricultural equipment, and mechanical drive lines that require constant-velocity output across moderate operating angles. It is applicable in both new installations and replacement scenarios where the existing joint has worn beyond serviceable limits.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDD-type double joint design cancels velocity variation caused by angular misalignment\u003c\/li\u003e\n\u003cli\u003e15,600 in\/lb torque capacity for heavy-duty mechanical drive applications\u003c\/li\u003e\n\u003cli\u003e1.5 inch bore depth accommodates standard shaft sizing\u003c\/li\u003e\n\u003cli\u003eBoot inside diameter of 1 inch and outside diameter of 2 inches\u003c\/li\u003e\n\u003cli\u003e10.875 inch overall assembly length for direct dimensional replacement planning\u003c\/li\u003e\n\u003cli\u003eSingle-unit packaging with a minimum order quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement for DD-type double universal joints in industrial and mechanical power transmission drive systems requiring 15,600 in\/lb torque capacity and a 1.5 inch bore depth.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified millwright or mechanical technician. Isolate and lock out all energy sources, including electrical and pneumatic, before removing the existing joint or installing the replacement. Verify shaft diameter, bore depth, and OAL against the application before final assembly. Consult applicable ANSI or OSHA machine guarding standards when reinstalling protective covers over the drive shaft assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTorque Capacity\u003c\/strong\u003e: 15,600 in\/lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Depth\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoot Inside Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoot Outside Diameter\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Assembly Length (OAL)\u003c\/strong\u003e: 10.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 8 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: 68514417056\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51540135674162,"sku":"68514417056","price":1264.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bf1801e1c01c57fec694c00dbf785f93_556b82c3-f49c-419f-9370-216dc1f2e2ac.jpg?v=1785846712","url":"https:\/\/voomisupply.com\/products\/lovejoy-68514417056-dd-type-double-universal-joint","provider":"Voomi Supply","version":"1.0","type":"link"}
