Lovejoy 68514476841 Flexible Clamp Hub 3/8 in Bore Adb

Product Description

The LOVEJOY 68514476841 is a clamp-style flexible coupling hub designed for shaft-to-shaft power transmission applications. Built from anodized aluminum, this hub accepts a 3/8 inch minimum bore diameter and measures 0.75 inches in outside diameter with an overall length of 1.04 inches. Rated at 12 inch-pounds of torque, it belongs to the ADB series of compact clamp hubs. The clamp style design allows secure shaft engagement without the need for keyways or set screws on all installations, making it a practical choice for motion control and light-duty drive train setups. Licensed mechanical technicians and industrial service professionals are the typical installers of this component.

This hub is suited for use in compact drive assemblies where precise shaft alignment and minimal backlash are required. The ADB series clamp hub is commonly found in HVAC blower drive configurations, pump drive trains, and light industrial motion control systems. Its anodized aluminum construction keeps weight low while providing corrosion resistance in typical indoor mechanical environments. At 0.04 pounds, the hub adds negligible rotational mass to the assembly.

Key Features

• Clamp-style bore engagement for secure shaft retention without additional fastening hardware
• Anodized aluminum construction provides corrosion resistance and reduced rotating mass
• 3/8 inch minimum bore diameter suits common small-shaft drive applications
• 0.75 inch outside diameter and 1.04 inch overall length fit space-constrained installations
• 12 inch-pounds torque rating appropriate for light-duty power transmission
• ADB series coupling size code ADB4 for straightforward replacement ordering

Compatibility

Designed as an OEM-style replacement clamp hub for use within the LOVEJOY ADB series flexible coupling system. Confirm bore diameter, outside diameter, and overall length against the existing hub before installation.

Installation Notes

Installation is typically performed by a qualified mechanical or HVAC technician. Disconnect and lock out all power to the drive system before removing or installing any coupling component. Confirm shaft and bore alignment before tightening the clamp hardware, as misalignment accelerates coupling wear. Do not exceed the rated torque specification when tightening clamp fasteners.
