Lovejoy 68514417114 Dd-type Double Universal Joint

Product Description

The LOVEJOY 68514417114 is a DD-type double universal joint designed to transmit rotational motion between two shafts that are not aligned on the same axis. This joint delivers up to 2,880 inch-pounds of torque and features a 1 inch bore depth, making it suited for moderate-to-heavy mechanical drive applications. The double-joint configuration reduces velocity variation compared to a single universal joint, which is critical in drive train assemblies where smooth power transfer is required. Mechanical technicians and millwrights typically install this component in industrial, agricultural, or heavy equipment drive systems.

This double universal joint is used in applications where two shafts must accommodate angular misalignment while maintaining consistent torque transmission. The 9/16 inch inside diameter and 1-1/8 inch outside diameter yoke dimensions, combined with a 7 inch overall length, make it a practical fit for compact drive shaft assemblies. It is commonly found in industrial machinery, agricultural equipment, and other rotating drive systems that require reliable double-jointed articulation under sustained load.

Compatibility

Designed as an OEM-style replacement or new-installation component for industrial, agricultural, and mechanical drive systems requiring a DD-type double universal joint with a 1 inch bore depth and 2,880 inch-pounds torque rating.

Installation Notes

Installation is typically performed by a qualified millwright or mechanical technician. Ensure all connected machinery is fully de-energized and locked out before removing or installing this joint. Verify shaft diameter and bore depth compatibility before assembly, and inspect yoke alignment to prevent premature wear. Follow equipment manufacturer guidelines for lubrication intervals on the joint cross and bearing cups.
