Lovejoy 68514417102 Dd-type Double Universal Joint

Product Description

The LOVEJOY 68514417102 is a DD-type double universal joint designed to transmit rotational motion between shafts that are misaligned or require angular flexibility. The double-joint configuration allows for greater angular deflection than a single universal joint while maintaining consistent torque transfer. Rated at 1,176 in/lbs of torque, this joint is built for demanding mechanical drive applications. With a 7/8 inch bore depth, a 7/16 inch inside diameter, and a 7/8 inch outside diameter, it fits a range of shaft and housing configurations. The overall assembled length is 6 inches. Mechanical technicians and millwrights typically install this component in industrial and commercial drive train systems.

This double universal joint is suited for use in mechanical drive assemblies where shaft misalignment must be accommodated without sacrificing torque capacity. Typical applications include industrial machinery, HVAC drive components, and other rotating equipment where angular offset between driving and driven shafts is present. The DD-type design provides a compact, inline solution for applications requiring dual-plane angular correction within a single joint assembly.

Key Features

• DD-type double universal joint for greater angular deflection than single U-joint designs
• 1,176 in/lbs torque rating for demanding rotational drive applications
• 7/8 inch bore depth and 7/16 inch inside diameter for precise shaft fitment
• 6 inch overall assembled length for compact inline installations
• Single-piece package quantity for individual replacement or repair use

Compatibility

Designed as an OEM-style replacement or aftermarket universal joint for mechanical drive assemblies requiring a DD-type double joint configuration with a 7/8 inch bore depth and 1,176 in/lbs torque capacity.

Installation Notes

Installation should be performed by a qualified mechanical technician or millwright. De-energize and lock out all power to the drive system before removing or installing this joint. Ensure shaft and bore dimensions are verified against the joint specifications before installation. Follow applicable machinery safety standards and the equipment manufacturer guidelines during reassembly.
