Lovejoy 68514476849 Flexible Clamp Hub Adb Series

Product Description

The LOVEJOY 68514476849 is a flexible clamp hub designed for use in flexible coupling assemblies on rotating drive systems. It features a clamp-style bore attachment that secures to a 0.5-inch minimum bore shaft, delivering a rated torque of 38 inch-pounds. Constructed from anodized aluminum, the hub offers corrosion resistance and reduced rotating mass. With an outside diameter of 1.25 inches and an overall length of 2.25 inches, this compact hub fits space-constrained mechanical drive applications. It belongs to the LOVEJOY ADB series and is installed by millwrights, HVAC mechanical technicians, and industrial maintenance trades handling pump, motor, and blower shaft couplings.

This clamp hub is suited for light-duty to medium-duty rotating equipment found in commercial HVAC systems, pump assemblies, and general industrial power transmission applications. The clamp-style attachment allows straightforward shaft engagement without requiring a keyway, making it practical for field replacement or new installations where quick alignment and secure shaft clamping are priorities. It ships as a single unit and is intended to be paired with the appropriate ADB series spider or mating hub to complete the flexible coupling assembly.

Key Features

• Clamp-style bore attachment for secure shaft engagement without a keyway requirement
• Anodized aluminum construction for corrosion resistance and lightweight performance
• Rated torque of 38 inch-pounds suitable for light-duty to medium-duty drive applications
• Minimum bore diameter of 0.5 inches fits standard small-shaft motors and pumps
• Part of the LOVEJOY ADB series for broad flexible coupling system compatibility
• Compact 1.25-inch OD and 2.25-inch OAL for space-constrained drive assemblies

Compatibility

Designed for use within the LOVEJOY ADB series flexible coupling system, coupling size code ADB6. Intended to be paired with a compatible ADB series mating hub and spider element to form a complete flexible jaw coupling assembly.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician. De-energize and lock out the drive motor and relieve any stored mechanical energy before handling coupling components. Verify shaft diameter falls within the specified bore range before installation, and ensure proper shaft and hub alignment to avoid premature spider wear. Refer to applicable ANSI and OSHA machinery guarding requirements when working on rotating drive equipment.
