Lovejoy 68514417177 Dd-type Double Universal Joint

Product Description

The LOVEJOY 68514417177 is a DD-type double universal joint designed to transmit rotational motion between shafts that are misaligned or require articulation across two planes. Rated at 15,600 inch-pounds of torque, this joint handles heavy-duty mechanical loads common in industrial drive systems. The double universal joint configuration uses two Cardan-style crosses to cancel velocity variation, producing smoother output than a single joint. It is installed by millwrights, mechanical technicians, and industrial maintenance professionals in power transmission applications where shaft angle changes are required.

This double universal joint is suited for industrial machinery, conveyor drives, pump drives, and similar power transmission systems where angular misalignment between the driving and driven shafts must be accommodated. The 1.5-inch bore depth and 1-inch inside diameter to 2-inch outside diameter envelope fit a range of shaft configurations in commercial and industrial equipment. It is a direct-fit mechanical component requiring no special tooling beyond standard shaft and coupling installation practices.

Key Features

• 15,600 inch-pounds torque rating for heavy-duty power transmission
• DD-type double universal joint design cancels velocity fluctuation across angular offsets
• 1.5-inch bore depth accommodates standard industrial shaft sizing
• 1-inch inside diameter with 2-inch outside diameter profile
• 10-7/8-inch overall length (OAL) for consistent dimensional fitment
• Package quantity of one unit per order

Compatibility

Designed as an OEM-style replacement or direct upgrade for DD-type double universal joint applications in industrial power transmission drive systems requiring a 1.5-inch bore depth and 15,600 inch-pounds torque capacity.

Installation Notes

Installation is performed by qualified millwrights or mechanical maintenance technicians. Disconnect and lock out all power to the drive system before removing the existing joint or installing this component. Ensure shaft surfaces are clean and free of burrs before seating the joint. Follow applicable machinery safety standards and the equipment manufacturer's service documentation for alignment and retention requirements.
