Lovejoy 68514476842 Flexible Clamp Hub 3/8 in Bore Adb

Product Description

The LOVEJOY 68514476842 is a clamp-style flexible coupling hub machined from anodized aluminum, designed for use in shaft coupling assemblies where lightweight construction and corrosion resistance are priorities. Part of the ADB series, this hub accepts a minimum bore diameter of 3/8 inch and measures 1 inch in outside diameter with an overall length of 1.5 inches. It is rated for 20 inch-pounds of torque. The clamp-style design allows secure shaft engagement without the need for set screws, making installation and repositioning straightforward in tight-tolerance drive train applications.

This hub is suited for light-duty power transmission applications in HVAC equipment, pumps, fans, and small motorized assemblies found in both residential and commercial settings. The ADB series clamp hub is typically installed by mechanical contractors, HVAC technicians, or equipment maintenance professionals working on flexible coupling systems that require precise shaft alignment and repeatable torque transfer. Its compact dimensions make it a practical choice where space around the coupling area is limited.

Key Features

• Clamp-style engagement for tool-free shaft adjustment and secure holding without set screws
• Anodized aluminum construction offers corrosion resistance at low weight (0.1 pounds)
• Minimum bore diameter of 3/8 inch suits common small-shaft applications
• 1 inch outside diameter and 1.5 inch overall length for compact installation envelopes
• Rated to 20 inch-pounds torque capacity for light-duty drive systems
• Part of the LOVEJOY ADB series for consistent coupling system compatibility

Compatibility

Designed as an ADB series clamp hub replacement or system component for flexible coupling assemblies requiring a 3/8 inch minimum bore, 1 inch OD hub in anodized aluminum construction.

Installation Notes

Installation is typically performed by a licensed mechanical or HVAC technician. Always de-energize and lock out the drive system before removing or installing any coupling component. Verify shaft diameter falls within the bore specification and confirm coupling alignment before torquing the clamp fasteners. Do not exceed the published torque rating of 20 inch-pounds during operation.
