Lovejoy 68514417224 Dd-type Double Universal Joint

Product Description

The LOVEJOY 68514417224 is a DD-type double universal joint engineered for high-torque shaft coupling applications. It delivers a rated torque of 65,400 in/lbs and features a 2.75-inch bore depth, making it suited to demanding drive train and power transmission assemblies. The double universal joint configuration allows for greater angular misalignment compensation compared to a single-joint design, reducing vibration and mechanical stress in the connected drivetrain. This part is installed by mechanical power transmission technicians and industrial maintenance professionals working on heavy-duty rotating equipment.

This double universal joint is intended for industrial power transmission systems where high torque loads and angular misalignment are present. It fits applications in industrial machinery, heavy equipment drivetrains, and similar rotating shaft systems requiring a rigid yet flexible coupling solution. With an inside diameter of 1.5 inches, an outside diameter of 3 inches, and an overall assembled length (OAL) of 18.125 inches, it is sized for mid-to-large shaft coupling installations. The 30.82-pound unit weight reflects the robust construction required for high-torque service.

Key Features

• 65,400 in/lbs rated torque capacity for heavy-duty drive applications
• DD-type double universal joint design accommodates greater angular misalignment than single-joint configurations
• 2.75-inch bore depth for secure shaft engagement
• 1.5-inch inside diameter and 3-inch outside diameter for precise shaft fitment
• 18.125-inch overall assembled length suits mid-to-large drivetrain installations
• Substantial 30.82-pound construction supports high-load, continuous-duty service

Compatibility

Designed as an OEM-style replacement or direct-fit universal joint for industrial power transmission shafting applications requiring a DD-type double universal joint with 1.5-inch inside diameter and 3-inch outside diameter bore configuration.

Installation Notes

Installation should be performed by a qualified mechanical technician familiar with industrial power transmission components. De-energize and lock out all connected drive equipment before disassembly or installation, following applicable LOTO procedures. Ensure shaft surfaces are clean and free of burrs before pressing or sliding the joint into position. Verify torque rating compatibility with the driven load before returning the system to service.
