Lovejoy 68514415774 D-type Single Universal Joint

Product Description

The LOVEJOY 68514415774 is a D-Type single universal joint designed for transmitting rotational motion between shafts that are misaligned or require angular flexibility. This joint handles a torque capacity of 1,176 inch-pounds, making it suitable for moderate-duty mechanical drive applications. The boot inside diameter measures 0.44 inches and the boot outside diameter measures 0.88 inches. It is installed by millwrights, mechanical contractors, and industrial maintenance technicians working on drive shaft assemblies, HVAC equipment, or general mechanical systems requiring flexible shaft couplings.

This universal joint fits applications where a compact, single-joint D-Type configuration is required. The 0.88-inch outside diameter and 0.44-inch inside diameter make it appropriate for small-bore shaft drive assemblies. Typical use cases include HVAC damper actuator linkages, light industrial drive trains, and equipment where angular misalignment between drive and driven shafts must be accommodated without sacrificing torque transmission.

Installation Notes

Installation is performed by qualified millwrights or mechanical technicians. Shut down and lock out all power to the drive system before removing or installing any shaft coupling components, following LOTO procedures per OSHA standards. Verify shaft alignment and bore dimensions before installation to ensure proper fit and avoid premature wear. Do not exceed the rated torque capacity during operation.
