Lovejoy 68514415718 D-type Single Universal Joint

Product Description

The LOVEJOY 68514415718 is a D-Type single universal joint designed to transmit rotational force through angled or misaligned drive shafts in mechanical drive systems. It handles a torque capacity of 540 inch-pounds, making it suitable for moderate-duty power transmission applications. The joint features an 11/16-inch bore depth with a 5/16-inch inside diameter boot and a 5/8-inch outside diameter boot. Overall assembled length is 2-1/4 inches. Licensed technicians and mechanical tradespeople working on drive train assemblies, HVAC equipment, or light industrial machinery typically install this component.

This universal joint is used in applications where a shaft must transmit torque across an angular offset. It fits residential and light commercial mechanical systems where compact, single-joint configurations are required. The D-Type designation indicates the joint body profile, which is common in compact drive assemblies where space and weight are limited. It is sold individually and packaged as a single unit per order.

Installation Notes

Installation should be performed by a qualified mechanical technician familiar with drive shaft and power transmission assemblies. Always de-energize and lock out the drive system before removing or installing any universal joint. Verify shaft alignment and angular offset are within the joint's rated operating range before finalizing the installation. Follow applicable mechanical and equipment manufacturer guidelines during service.
