Lovejoy 68514476848 Flexible Clamp Hub Adb Series

Product Description

The LOVEJOY 68514476848 is a clamp-style flexible coupling hub machined from anodized aluminum, designed for use in mechanical drive systems where shaft-to-shaft alignment and vibration damping are required. Part of the ADB series, this hub features a 1/2 inch minimum bore diameter, a 1.25 inch outside diameter, and an overall length of 2.25 inches. It is rated for 38 inch-pounds of torque. The anodized aluminum construction offers corrosion resistance and light weight, making it suitable for a range of industrial and mechanical power transmission applications. Licensed technicians and mechanical tradespeople install this component as part of a complete flexible coupling assembly.

This hub is suited for light-duty to medium-duty mechanical drive installations where a compact, corrosion-resistant coupling component is needed. It is intended for use in the ADB coupling series and pairs with the corresponding spider or insert element and mating hub to complete the coupling assembly. Typical applications include pump drives, conveyor systems, compressor drives, and other rotating equipment found in commercial and industrial settings.

Key Features

• Clamp-style hub design for secure shaft retention without set screws
• Anodized aluminum construction for corrosion resistance and reduced weight
• 1/2 inch minimum bore diameter accommodates common small-shaft drive configurations
• 1.25 inch outside diameter and 2.25 inch overall length for compact installation
• 38 inch-pounds torque rating suitable for light-duty to medium-duty drive applications
• Part of the ADB series for standardized replacement and interchangeability

Compatibility

Designed as an OEM-style replacement hub within the LOVEJOY ADB series flexible coupling system. Must be paired with the matching ADB series spider element and mating hub to form a complete coupling assembly.

Installation Notes

Installation should be performed by a qualified mechanical technician. Disconnect and lock out all power to rotating equipment before handling any coupling components. Ensure shaft and bore surfaces are clean and free of burrs before fitting the hub. Clamp-style hubs require proper fastener torque per the coupling manufacturer guidelines to achieve rated holding force — do not overtighten.
