Lovejoy 68514431174 D-type Single Universal Joint

Product Description

The LOVEJOY 68514431174 is a D-type single universal joint designed to transmit rotational motion between shafts that are misaligned or require angular flexibility. Rated at 5,280 inch-pounds of torque, this joint is built for demanding mechanical drive applications where a reliable, compact coupling solution is required. The boot measures 0.75 inches inside diameter and 1.5 inches outside diameter, with a bore depth of 1-3/16 inches and an overall length of 4-1/4 inches. It is typically installed by millwrights, mechanical contractors, or industrial maintenance technicians working on drive shaft and power transmission assemblies.

This universal joint is suited for use in power transmission systems where shaft angles or positional offsets require a flexible coupling. Typical applications include industrial drive assemblies, mechanical linkages, and equipment requiring torque transfer across an angular joint. The compact envelope and defined bore geometry make it a practical fit for retrofit and new-installation scenarios in light to medium industrial settings.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician familiar with power transmission components. Disconnect and lock out all power sources before removing the existing joint or installing this unit. Verify shaft diameter and bore depth compatibility before installation, and ensure all fasteners are properly secured to the manufacturer's specified torque using calibrated tools. Follow applicable ANSI and OSHA guidelines for mechanical power transmission guarding after installation is complete.
