Lovejoy 68514431183 D-type Single Universal Joint

Product Description

The LOVEJOY 68514431183 is a D-type single universal joint designed to transmit rotational motion between shafts that are misaligned or set at an angle. Rated at 10,400 inch-pounds of torque, it handles demanding drive applications in industrial and mechanical systems. The joint features a 1-inch inside diameter bore, a 2-inch outside diameter, a 1.5-inch bore depth, and an overall length (OAL) of 5-7/16 inches. It weighs 3.5 pounds. Mechanical technicians and millwrights typically install this type of joint in power transmission assemblies where rigid couplings are not suitable due to angular offset between drive and driven shafts.

This universal joint is suited for use in industrial machinery, material handling equipment, and mechanical drive systems that require flexible shaft connections under moderate to high torque loads. The single-joint D-type configuration is a common choice for applications where one plane of angular misalignment must be accommodated. It is typically installed by mechanical or industrial maintenance technicians working on power transmission line shafts, conveyors, and similar rotating equipment.

Key Features

• 10,400 inch-pounds torque rating for heavy-duty power transmission
• D-type single universal joint design accommodates angular shaft misalignment
• 1-inch inside diameter bore with 1.5-inch bore depth

• 3.5-pound unit weight suitable for direct shaft mounting

Compatibility

Designed as an OEM-style replacement or direct-fit universal joint for industrial power transmission shafts requiring a single D-type joint with a 1-inch bore and 10,400 inch-pound torque capacity.

Installation Notes

Installation should be performed by a qualified mechanical technician or millwright. Always de-energize and lock out the drive system before removing or installing universal joints. Verify shaft diameter and bore fit before pressing or fastening the joint. Ensure proper angular alignment does not exceed the designed operating angle for the joint to prevent premature wear or failure.
