Lovejoy 68514431166 D-type Single Universal Joint

Product Description

The LOVEJOY 68514431166 is a D-type single universal joint designed for mechanical power transmission in shaft-to-shaft drive applications. It features a 1040 in/lb torque rating, a 0.5 inch inside (bore) diameter, and a 1 inch outside diameter boot, making it suitable for compact drive assemblies where angular misalignment must be accommodated. Licensed millwrights, mechanical contractors, and industrial maintenance technicians typically install this type of joint in equipment drives, HVAC mechanical linkages, and other rotating-shaft systems where a rigid coupling is not practical.

This universal joint is suited for residential and light commercial mechanical applications as well as industrial equipment where shaft misalignment or directional changes are required. The D-type single configuration provides a single-plane pivot point appropriate for low-to-moderate angle drive arrangements. It is sold individually, making it a direct replacement or spare part acquisition for a single-joint position in a drive train.

Key Features

• 1040 in/lb torque capacity for moderate-duty shaft drive applications
• 0.5 inch inside diameter accommodates standard half-inch shafting
• 1 inch outside diameter boot fits compact drive housings
• D-type single joint design allows angular misalignment in a single plane
• Sold as individual unit with no minimum order requirement beyond one piece

Compatibility

Designed as an OEM-style replacement single universal joint for mechanical shaft drive assemblies requiring a 0.5 inch bore and 1 inch outside diameter with a D-type single joint configuration.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician. De-energize and lock out all power to the drive system before removing or installing any shaft coupling components, following OSHA lockout/tagout procedures. Ensure shaft and bore dimensions are confirmed before installation, and verify that operating angles do not exceed the joint's rated misalignment capacity. Do not apply impact force to the joint body during installation on the shaft.
