Lovejoy 68514476846 Flexible Clamp Hub 3/8 in Bore Adb

Product Description

The LOVEJOY 68514476846 is a flexible clamp hub designed for use in mechanical power transmission systems. Part of the ADB series, this clamp-style hub accepts a minimum bore diameter of 3/8 inches and measures 1.25 inches in outside diameter with an overall length of 2.25 inches. Constructed from anodized aluminum, it offers corrosion resistance while keeping weight low at 0.23 pounds. Rated for up to 38 in/lb of torque, it is well suited for light-duty coupling applications. Installation is handled by millwrights, maintenance technicians, and mechanical contractors working on motors, pumps, and similar rotating equipment.

This clamp hub is intended for use in flexible coupling assemblies where shaft-to-shaft power transmission is required. The clamp-style design allows for secure shaft engagement without requiring a keyway, simplifying installation in tight spaces. It is commonly used in HVAC equipment, pump drives, and general industrial machinery where a compact, corrosion-resistant hub is specified. The ADB series designation identifies the coupling size family for ordering matched hubs and center elements.

Key Features

• Clamp-style design secures to shaft without a keyway for straightforward installation
• Anodized aluminum construction provides corrosion resistance with reduced weight
• 38 in/lb torque rating suitable for light-duty power transmission applications
• 3/8 inch minimum bore diameter accommodates common small-shaft sizes
• Compact form factor: 1.25 inches OD and 2.25 inches overall length
• ADB series sizing allows matching with compatible flexible coupling center elements

Compatibility

Designed as an OEM-style replacement or new-installation clamp hub within the LOVEJOY ADB series flexible coupling system. Compatible with ADB series coupling assemblies using the ADB6 size code. Verify bore diameter and coupling size code against the mating hub and center element before ordering.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician. De-energize and lock out the drive motor and any associated equipment before handling coupling components. Ensure shaft and bore surfaces are clean and free of burrs before seating the hub. Follow the equipment manufacturer torque specifications for clamp fasteners and verify shaft alignment before returning the system to service.
