Lovejoy 68514476857 Flexible Clamp Hub Adb Series

Product Description

The LOVEJOY 68514476857 is an ADB Series flexible clamp hub designed for use in shaft coupling assemblies. This component connects rotating shafts while accommodating minor misalignment, reducing vibration transfer between connected machinery. Constructed from anodized aluminum, it offers corrosion resistance with a lightweight profile. The hub accepts a minimum bore diameter of 5/8 inches and measures 1.5 inches in outside diameter with an overall length of 2.63 inches. It is rated for up to 88 inch-pounds of torque. Mechanical and HVAC technicians, as well as industrial maintenance professionals, typically install this type of coupling hub during equipment assembly or drivetrain service.

The ADB Series clamp-style hub is suited for light-to-medium duty rotating shaft applications across commercial HVAC equipment, pumps, fans, and general industrial machinery. The clamp style design allows secure shaft engagement without requiring a keyway, simplifying installation and removal. This hub is intended for use as one half of a complete flexible coupling assembly and must be paired with a compatible spider insert and mating hub to complete the coupling.

Installation Notes

Installation and removal should be performed by a qualified mechanical or HVAC technician. De-energize and lock out all power to rotating equipment before servicing any coupling components. Ensure shaft surfaces are clean and free of burrs before seating the hub bore. Do not operate the coupling without the full assembly, including the spider insert and mating hub, properly installed and fastened.
