Lovejoy 68514417038 Dd-type Double Universal Joint

Product Description

The LOVEJOY 68514417038 is a DD-type double universal joint designed to transmit rotary motion between shafts that are misaligned or require angular articulation. It is rated at 2,880 inch-pounds of torque and features a bore depth of 1 inch. The inner diameter measures 9/16 inch and the outer diameter measures 1-1/8 inches, with an overall length of 7 inches. This type of double-joint configuration reduces the velocity fluctuation common in single universal joints, making it well suited for drive shaft and mechanical linkage applications in industrial and commercial equipment. Installation is typically performed by mechanical technicians and maintenance professionals.

DD-type double universal joints are used in mechanical drive systems where two shafts must transmit torque across a significant angle or where constant-velocity output is required. Common applications include industrial machinery, mechanical steering linkages, actuator drives, and power transmission assemblies in commercial equipment. The 2,880 in/lb torque rating supports moderate to heavy-duty mechanical loads. The compact 7-inch overall length makes this joint suitable for installations with limited axial clearance.

Key Features

• DD-type double universal joint design reduces output velocity variation across angular misalignment
• 2,880 inch-pound torque rating supports moderate to heavy-duty mechanical drive loads
• 1 inch bore depth with 9/16 inch inside diameter and 1-1/8 inch outside diameter for precise shaft fitment
• 7 inch overall length suits installations with limited axial space
• Sold and packaged as a single unit for direct replacement or new installation

Compatibility

Designed as an OEM-style replacement or upgrade joint for mechanical drive and power transmission assemblies requiring a DD-type double universal joint with a 9/16 inch inside diameter and 2,880 in/lb torque capacity.

Installation Notes

This joint should be installed by a qualified mechanical technician familiar with power transmission components. Disconnect and de-energize all drive power before removing the existing joint or handling the replacement. Ensure shaft alignment and bore sizing are confirmed before final assembly, and verify that the torque load of the application does not exceed the rated 2,880 in/lb. Consult applicable machinery safety standards and the equipment manufacturer's service documentation during installation.
