Lovejoy 68514416753 D-type Single Universal Joint

Product Description

The LOVEJOY 68514416753 is a D-type single universal joint designed to transmit rotational motion between shafts that are misaligned or positioned at an angle. It handles a torque capacity of 15,600 in/lb, making it suited for demanding mechanical drive applications in industrial, HVAC, and equipment service environments. The joint features a 1-inch inside diameter boot and a 2-inch outside diameter, with a 1-1/2-inch bore depth. Licensed mechanical and equipment technicians typically install this component during drivetrain assembly or repair work where flexible coupling and angular shaft compensation are required.

This universal joint is used in mechanical power transmission systems where two shafts must transfer torque across an angular offset. Typical install scenarios include fan drives, pump drives, and equipment linkages found in commercial and industrial settings. The D-type single configuration suits applications requiring a compact, single-joint assembly rather than a double-joint or constant-velocity style. It is appropriate for both new equipment builds and replacement service situations where the original joint has worn or failed.

Key Features

• 15,600 in/lb torque capacity for heavy-duty mechanical drive use
• D-type single universal joint configuration for angular shaft misalignment
• 1-inch inside diameter with 2-inch outside diameter boot dimensions
• 1-1/2-inch bore depth for shaft engagement
• Compact single-joint design suited for space-constrained drivetrain assemblies

Compatibility

Designed as an OEM-style replacement single universal joint for mechanical drive systems requiring a D-type joint with a 1-inch inside diameter, 2-inch outside diameter, and 15,600 in/lb torque rating.

Installation Notes

Installation is typically performed by a licensed millwright, mechanical technician, or equipment service professional. Shut down and lock out the equipment per OSHA lockout/tagout procedures before removing or installing the joint. Verify shaft diameter and bore depth match the joint specifications before pressing or fastening. Do not exceed the rated torque capacity during operation, as overloading can cause premature joint failure or equipment damage.
