Lovejoy 68514476850 Flexible Clamp Hub 5/8 in Bore

Product Description

The LOVEJOY 68514476850 is a flexible clamp hub designed for use in flexible shaft coupling assemblies. Part of the ADB series, this clamp-style hub accepts a 5/8 inch minimum bore diameter and measures 1.25 inches in outside diameter with an overall length of 2.25 inches. Constructed from anodized aluminum, it offers a lightweight yet durable build suited for mechanical power transmission applications. The clamp hub transmits torque up to 38 inch-pounds and is installed by licensed mechanics and millwrights or HVAC and industrial technicians working on coupled shaft systems requiring flexible connections.

This clamp hub is appropriate for residential and light commercial mechanical systems where flexible couplings are used to connect shafts on motors, pumps, compressors, and similar rotating equipment. The ADB series clamp style allows secure shaft engagement without the need for set screws, making it a practical choice for applications where vibration dampening and shaft misalignment tolerance are required. It ships as a single unit and is intended as a direct replacement or new-installation component in compatible flexible coupling assemblies.

Key Features

• Clamp-style hub design for secure shaft engagement without set screws
• Anodized aluminum construction for lightweight durability and corrosion resistance
• 5/8 inch minimum bore diameter for compatibility with standard shaft sizes
• Rated up to 38 inch-pounds of torque transmission
• ADB series coupling with a 1.25 inch outside diameter and 2.25 inch overall length

Compatibility

Designed as a replacement or new-installation clamp hub for use within LOVEJOY ADB series flexible coupling assemblies. Specific coupling compatibility is determined by bore diameter, outside diameter, and series code MADB6.

Installation Notes

Installation should be performed by a qualified mechanic or technician familiar with flexible shaft coupling systems. De-energize and lock out all power to the connected equipment before beginning work, following applicable OSHA lockout/tagout procedures. Ensure the shaft and hub bore are clean and free of burrs before fitting. Do not exceed the rated torque capacity of 38 inch-pounds when securing the clamp fasteners.
