Lovejoy 68514476837 Flexible Clamp Hub 5/16 in Bore Adb

Product Description

The LOVEJOY 68514476837 is a clamp-style flexible coupling hub designed for shaft-to-shaft power transmission applications. Built from anodized aluminum, this hub accepts a minimum bore diameter of 5/16 inches and measures 0.63 inches in outside diameter with an overall length of 1 inch. Part of the ADB Series, it uses a clamp-style engagement to secure onto a shaft without requiring a keyway, making installation straightforward in tight spaces. With a rated torque of 6.20 inch-pounds, it is suited for light-duty motion control and drive train connections. Mechanical technicians and equipment service technicians are the typical installers for this component.

This flexible clamp hub is used in light-duty motion control assemblies, small drive systems, and precision coupling applications where compact dimensions and low rotating mass are required. The ADB Series is commonly found in residential and light commercial equipment, instrumentation drives, and small motor coupling setups. Its anodized aluminum construction resists corrosion in typical indoor mechanical environments. The clamp-style hub eliminates the need for set screws against the shaft bore, reducing the risk of shaft damage during assembly.

Key Features

• Clamp-style hub design secures to shaft without set screw contact damage
• Anodized aluminum construction for corrosion resistance and low weight
• Compact 1 inch overall length fits tight drive train spaces
• 0.63 inch outside diameter for use in small coupling assemblies
• Rated torque of 6.20 inch-pounds for light-duty applications
• Part of the ADB Series with coupling size code ADB3.5

Compatibility

Designed as an OEM-style replacement or upgrade hub for ADB Series flexible coupling assemblies requiring a clamp-style hub with a 5/16 inch minimum bore diameter.

Installation Notes

Installation is typically performed by a mechanical or equipment technician. De-energize and lock out all power to the drive system before servicing any coupling component. Confirm shaft diameter is within the hub bore specification before assembly. Do not exceed the rated torque of 6.20 inch-pounds when tightening the clamp hardware to avoid deforming the hub bore.
