Lovejoy 68514417020 Dd-type Double Universal Joint

Product Description

The LOVEJOY 68514417020 is a DD-type double universal joint designed to transmit torque between shafts that are misaligned or offset in industrial and mechanical drive applications. Rated at 1,176 in/lbs of torque, this double-joint configuration provides two pivot points in a single assembly, allowing it to accommodate greater angular misalignment than a single universal joint. It features a 7/16-inch inside diameter, a 7/8-inch outside diameter, and an overall length of 6 inches. The bore depth measures 7/8 inches. Licensed HVAC, mechanical, and industrial technicians install these joints in drive systems where flexible coupling is required.

This double universal joint suits mechanical power transmission applications in light industrial, HVAC, and equipment-drive contexts. The DD-type geometry makes it appropriate for drive shaft assemblies where shaft centerlines are offset or angled and a single pivot point would not provide adequate articulation. It weighs 0.88 pounds and is sold individually.

Key Features

• DD-type double-pivot construction accommodates greater angular misalignment than single U-joints
• 1,176 in/lbs torque rating for demanding mechanical drive applications
• 7/8-inch bore depth with 7/16-inch inside diameter and 7/8-inch outside diameter
• 6-inch overall length for compact drive shaft installations
• Sold as a single unit with no minimum order quantity beyond one

Compatibility

Designed as an OEM-style replacement or drop-in component for mechanical drive shaft assemblies requiring a DD-type double universal joint with a 7/16-inch inside diameter and 7/8-inch outside diameter interface.

Installation Notes

Installation is performed by qualified mechanical or HVAC technicians. Always de-energize and lock out the drive system before removing or installing universal joints. Confirm shaft alignment and angular offset are within the rated limits of this joint before final assembly. Inspect mating shaft surfaces for wear or damage prior to installation to ensure proper seating and torque transfer.
