Lovejoy 68514476839 Flexible Clamp Hub Adb Series

Product Description

The LOVEJOY 68514476839 is a clamp-style flexible coupling hub designed for use in light-duty power transmission applications. Part of the ADB series, this hub accepts a minimum bore diameter of 0.25 inches and measures 0.75 inches in outside diameter with an overall length of 1.04 inches. Constructed from anodized aluminum, it delivers a corrosion-resistant, lightweight solution rated to 12 inch-pounds of torque. This component is installed by mechanical, HVAC, or industrial maintenance technicians where shaft-to-shaft misalignment compensation is required in compact drive assemblies.

The ADB series clamp hub is suited for residential and light commercial equipment where space constraints demand a compact coupling profile. Typical applications include small motor-to-shaft connections in HVAC equipment, pumps, and other rotating machinery. The clamp-style design allows for secure shaft retention without set screws, simplifying installation and removal during routine service. Its anodized aluminum construction makes it appropriate for environments where weight reduction and corrosion resistance are priorities.

Key Features

• Clamp-style retention for secure shaft grip without set screws
• Anodized aluminum construction provides corrosion resistance and reduced weight
• Compact profile: 0.75 inches OD and 1.04 inches overall length
• Rated to 12 inch-pounds of torque
• Minimum bore diameter of 0.25 inches suits small-shaft applications
• ADB series sizing code ADB4 for consistent replacement sourcing

Compatibility

Designed as an OEM-style replacement clamp hub for ADB series flexible couplings requiring a coupling size code of ADB4 with a 0.25-inch minimum bore diameter.

Installation Notes

Installation should be performed by a qualified mechanic or technician familiar with power transmission components. Disconnect and lock out all power to the drive system before removing or installing coupling components. Ensure shaft surfaces are clean and free of burrs before seating the hub. Follow applicable ANSI and equipment manufacturer guidelines for coupling alignment and torque specification.
