Lovejoy 68514476847 Flexible Clamp Hub 3/8 in Bore Adb

Product Description

The LOVEJOY 68514476847 is a flexible clamp hub designed for use in shaft coupling assemblies across industrial and mechanical drive applications. Part of the ADB series, this hub features a clamp-style bore that secures directly onto shafts or pipes with a minimum bore diameter of 3/8 inches. Constructed from anodized aluminum, it offers a lightweight build with corrosion resistance suited for demanding service environments. With an outside diameter of 1.25 inches and an overall length of 2.25 inches, this compact hub fits into tight mechanical spaces. It is rated for up to 38 inch-pounds of torque, making it appropriate for light-to-medium duty coupling configurations. Mechanical technicians and industrial maintenance professionals are the primary installers of this component.

This clamp hub is used in flexible coupling assemblies where axial misalignment compensation and vibration damping are required. Typical installations include pump drives, conveyor systems, small motor couplings, and HVAC equipment drive trains. The clamp-style design allows for tool-accessible shaft engagement without requiring keyways, simplifying installation in field service and replacement scenarios. Its anodized aluminum construction also makes it a practical choice in environments where weight reduction is a consideration alongside moderate torque transmission demands.

• Part of the ADB series, coupling size code ADB6

Compatibility

Designed as an OEM-style replacement or service component for flexible coupling assemblies using ADB series hubs with a 3/8 inch minimum bore diameter and clamp-style engagement.

Installation Notes

Installation should be performed by a qualified mechanical technician. Power down and de-energize all connected drive equipment before disassembling or installing coupling components. Ensure the shaft surface is clean and free of burrs before seating the clamp hub, and verify that the bore diameter matches the shaft diameter before tightening the clamp fasteners. Follow the equipment manufacturer's coupling alignment procedures after installation to prevent premature hub or coupling element wear.
