Lovejoy 68514417011 Dd-type Double Universal Joint

Product Description

The LOVEJOY 68514417011 is a DD-Type double universal joint designed to transmit rotational motion between shafts that are misaligned or require angular flexibility. This joint features an 11/16 inch bore depth, a 540 in/lb torque rating, and an overall length of 4.5 inches. The inner diameter measures 5/16 inches and the outer diameter measures 5/8 inches. Double universal joints are used where a single U-joint cannot adequately compensate for angular offset, making this part a common solution in mechanical drive systems requiring smooth power transfer across compound angles. Licensed mechanics and millwrights typically install this component in industrial and commercial drive train assemblies.

The LOVEJOY 68514417011 is suited for mechanical drive applications where dual angular compensation is required. Its compact overall length of 4.5 inches and defined bore geometry make it appropriate for tight installations in industrial equipment, machinery linkages, and shaft coupling assemblies. It is sold individually in single-unit packaging with a minimum order quantity of one.

Key Features

• DD-Type double universal joint design for dual angular misalignment compensation
• 540 in/lb torque capacity for reliable power transmission under load
• 11/16 inch bore depth with 5/16 inch inside diameter and 5/8 inch outside diameter
• Compact 4.5 inch overall length for space-constrained installations
• Single-unit packaging with no multi-unit minimum order requirement

Compatibility

Designed as an OEM-style replacement or direct-fit double universal joint for mechanical drive shaft assemblies requiring DD-Type coupling geometry with a 5/16 inch inside diameter and 5/8 inch outside diameter bore configuration.

Installation Notes

Installation is typically performed by licensed mechanics or millwrights working on mechanical drive systems. Shut down and lock out all power to the drive assembly before removing or installing the joint. Verify shaft alignment and bore dimensions against equipment specifications before installation. Do not exceed the rated torque of 540 in/lb during operation.
