Lovejoy 68514436062 Flexible Coupling Hub 1 in Bore

Product Description

The LOVEJOY 68514436062 is a flexible coupling hub designed for power transmission applications in industrial and mechanical drive systems. Manufactured from cast iron, this hub accepts a maximum bore diameter of 1 inch and includes a keyway measuring 1/4 inch wide by 1/8 inch deep for positive shaft engagement. The hub measures 3.25 inches in outer diameter and 2.88 inches in overall length. It is rated to a maximum speed of 7,600 RPM, making it suitable for a wide range of motor-to-load coupling configurations. Licensed mechanics, millwrights, and HVAC technicians working on direct-drive systems are the typical installers.

This coupling hub is used in industrial machinery, HVAC equipment, pumps, compressors, and other rotating equipment where flexible shaft coupling is required. The flexible coupling design accommodates minor shaft misalignment and reduces vibration transmission between connected shafts. Coupling Size Code 5J identifies the hub series for matching with compatible spider inserts and mating hubs in the same family. It is appropriate for both light commercial and industrial installations where cast iron construction is acceptable for the operating environment.

Installation Notes

Installation should be performed by a qualified millwright, mechanic, or technician familiar with power transmission coupling assemblies. Disconnect and lock out all power to the drive system before handling any coupling components. Ensure shaft and bore tolerances are verified before pressing or fitting the hub, and confirm keyway alignment before securing with appropriate fasteners. Follow applicable ANSI or manufacturer torque guidelines for set screws or retaining hardware as specified in the equipment service documentation.
