Lovejoy 68514476831 Flexible Clamp Hub Adb Series

Product Description

The LOVEJOY 68514476831 is a flexible clamp hub designed for use in shaft coupling assemblies. Part of the ADB series, this clamp-style hub accepts a minimum bore diameter of 3/16 inches and features a 1/2 inch outside diameter with an overall length of 0.9 inches. Constructed from anodized aluminum, it offers lightweight corrosion resistance suited for mechanical drive applications. Rated at 3.50 inch-pounds of torque, this hub is a compact component installed by mechanical technicians and maintenance professionals working on light-duty power transmission systems.

This clamp hub fits residential and light commercial mechanical drive assemblies where precise shaft coupling is required. The ADB series clamp style simplifies installation and removal without the need for specialized tooling, making it well suited for equipment that requires periodic maintenance or shaft repositioning. It is commonly used in HVAC blower assemblies, small motor drives, and similar low-torque rotating equipment where aluminum construction is appropriate.

Compatibility

Designed as an OEM-style replacement clamp hub for flexible shaft coupling assemblies requiring ADB series components with a 3/16 inch minimum bore and 1/2 inch outside diameter.

Installation Notes

Installation should be performed by a qualified mechanical technician. Disconnect and lock out all power to the drive system before servicing any coupling components. Ensure the shaft is clean and free of burrs before seating the clamp hub, and verify bore and shaft diameters match before final tightening. Do not exceed the rated torque capacity of the coupling assembly.
