Lovejoy 68514417061 Dd-type Double Universal Joint

Product Description

The LOVEJOY 68514417061 is a DD-Type double universal joint designed to transmit rotational torque through angular misalignment in industrial and mechanical drive systems. Rated at 33,120 inch-pounds of torque, it is built for demanding power-transmission applications where a single universal joint would be insufficient. The joint features a 2-inch bore depth, a 1-1/4-inch inside diameter, and a 2-1/2-inch outside diameter, with an overall assembly length of 14 inches. At 17 pounds, it is a heavy-duty component typically installed by mechanical or industrial maintenance technicians working on drive shafts, machine tools, or similar equipment.

This double universal joint is suited for industrial machinery, heavy equipment, and mechanical drive assemblies where high torque capacity and accommodation of angular shaft misalignment are required. The DD-type double-joint configuration reduces vibration and secondary couple effects compared to a single U-joint, making it appropriate for applications where smooth torque transmission at varying operating angles is critical. It is packaged individually as a single unit.

Key Features

• 33,120 inch-pound torque rating for heavy-duty drive applications
• DD-Type double universal joint design reduces secondary couple and vibration
• 2-inch bore depth with 1-1/4-inch inside diameter and 2-1/2-inch outside diameter
• 14-inch overall assembly length (OAL)
• Heavyweight construction at 17 pounds for durability under load

Compatibility

Designed as an OEM-style replacement or direct-fit component for industrial drive shaft assemblies and mechanical power-transmission systems requiring a DD-type double universal joint with a 33,120 inch-pound torque rating and matching bore dimensions.

Installation Notes

Installation should be performed by a qualified mechanical technician familiar with power-transmission components and drive shaft service procedures. Fully de-energize and lock out the drive system before removing or installing any universal joint. Verify that shaft dimensions, bore depth, and alignment angles are within the joint's rated specifications before final assembly. Consult applicable machinery manufacturer guidelines and relevant ANSI or OSHA lockout/tagout procedures during service.
