Lovejoy 68514416698 D-type Single Universal Joint

Product Description

The LOVEJOY 68514416698 is a D-Type single universal joint designed to transmit rotational torque between shafts that are misaligned or require angular flexibility. It is rated for 10,680 inch-pounds of torque and features a 1-3/8 inch bore depth, a 7/8 inch inside diameter, and a 1-3/4 inch outside diameter, with an overall length of 5 inches. This type of joint is a standard mechanical power-transmission component found in industrial machinery, HVAC drive assemblies, and similar rotating equipment. Installation is typically performed by millwrights, mechanical contractors, or experienced maintenance technicians.

This universal joint is suited for applications where moderate-to-high torque must be transferred across an angular shaft offset. Common install scenarios include fan drive shafts, pump drive assemblies, and general power-transmission systems in both commercial and light industrial environments. The D-Type single configuration provides a compact, single-joint solution for applications that do not require a double-joint constant-velocity arrangement.

Key Features

• Rated torque of 10,680 inch-pounds for demanding power-transmission applications
• 1-3/8 inch bore depth accommodates standard shaft sizing
• 7/8 inch inside diameter by 1-3/4 inch outside diameter cross section
• 5 inch overall length for compact inline installation
• D-Type single universal joint design for straightforward angular misalignment compensation

Compatibility

Designed as an OEM-style replacement or direct-fit universal joint for rotating power-transmission assemblies requiring a D-Type single joint configuration with a 10,680 inch-pound torque rating and 1-3/8 inch bore depth.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician. Disconnect and lock out all power to the drive system before removing or installing this joint. Ensure shaft and bore surfaces are clean and free of burrs before fitting, and verify that angular misalignment does not exceed the joint design limit for the application. Follow applicable machinery safety codes and the equipment manufacturer guidelines during reassembly.
