Lovejoy 68514415674 D-type Single Universal Joint

Product Description

The LOVEJOY 68514415674 is a D-type single universal joint designed to transmit rotational torque through angular misalignment in mechanical drive systems. It carries a torque capacity of 378 inch-pounds and features a 5/8-inch bore depth with a 0.25-inch inside diameter boot and a 0.5-inch outside diameter boot. The overall assembly length is 2 inches. This joint is installed by millwrights, HVAC mechanics, and general mechanical technicians in applications where shaft alignment cannot be held perfectly straight.

This universal joint suits light-duty to medium-duty mechanical drive assemblies where compact size and reliable torque transfer are required. The D-type single configuration handles a single plane of angular deflection, making it appropriate for fans, blowers, small conveyor drives, and similar rotating equipment found in commercial and industrial settings. Its compact 2-inch overall length fits in space-constrained drive trains.

Key Features

• 378 inch-pound torque capacity handles moderate rotational loads
• D-type single joint design accommodates single-plane angular misalignment
• 5/8-inch bore depth fits standard shaft sizes in light industrial drives
• 0.25-inch inside diameter and 0.5-inch outside diameter boot dimensions
• Compact 2-inch overall length suits space-restricted installations

Compatibility

Designed as an OEM-style replacement or direct-fit universal joint for light-duty to medium-duty mechanical drive shafts requiring a D-type single joint configuration with a 5/8-inch bore depth and 378 inch-pound torque rating.

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 surfaces are clean and free of burrs before seating the joint, and verify that the angular misalignment of the application does not exceed the rated limits of the D-type single joint design. Consult applicable ANSI or equipment manufacturer guidelines for torque transmission and shaft fitment requirements.
