Lovejoy 68514476835 Flexible Clamp Hub 1/4 in Bore

Product Description

The LOVEJOY 68514476835 is a clamp-style flexible coupling hub made from anodized aluminum. It is designed for use in the ADB series coupling line and accepts a minimum bore diameter of 1/4 inch. The hub measures 0.63 inches in outside diameter and 1.0 inch in overall length, with a rated torque capacity of 6.20 inch-pounds. Flexible clamp hubs connect rotating shafts in mechanical drive systems and are commonly installed by millwrights, HVAC technicians, and industrial maintenance professionals where shaft misalignment compensation and easy hub removal are required.

This hub is suited for light-duty rotating shaft applications where a compact, corrosion-resistant coupling component is needed. The clamp-style design allows secure shaft engagement without the need for set screws, making it a practical choice for equipment with small shaft diameters. The anodized aluminum construction keeps weight low while providing a surface finish that resists oxidation in moderate service environments. Typical install scenarios include small motor-to-gearbox connections, pump drives, and fan shaft assemblies in residential and light commercial mechanical systems.

Installation Notes

Installation is typically performed by a qualified millwright or mechanical technician. De-energize and lock out all power to the drive system before servicing any coupling component. Verify shaft diameter matches the hub bore specification before assembly, and inspect the mating coupling element for wear before reinstalling. Follow equipment manufacturer alignment procedures to stay within the coupling's rated misalignment tolerance.
