Lovejoy 68514476855 Flexible Clamp Hub 1.5in Od Anodized Aluminum

Product Description

The LOVEJOY 68514476855 is a flexible clamp-style coupling hub machined from anodized aluminum, designed for use in mechanical power transmission applications. Part of the ADB series, this hub accepts a minimum bore diameter of 0.5 inches and features a 1.5-inch outside diameter with an overall length of 2.63 inches. The clamp hub design allows secure shaft engagement without set screws, using a split-clamp clamping method for reliable torque transfer. It is sized for light-to-medium duty applications and is typically installed by mechanical contractors, HVAC technicians, and industrial maintenance personnel working on rotating equipment such as pumps, blowers, and compressor assemblies.

This hub is suited for residential and commercial mechanical systems where a lightweight, corrosion-resistant coupling component is required. The anodized aluminum construction makes it appropriate for installations where weight savings and resistance to oxidation are priorities. The ADB series designation indicates it pairs with a compatible spider insert and mating hub to form a complete flexible jaw coupling assembly. Applications include pump drives, fan assemblies, and other direct-drive configurations common in HVAC and light industrial environments.

Key Features

• Clamp-style hub design provides secure shaft grip without set screw marring
• Anodized aluminum construction offers corrosion resistance and reduced weight
• Rated torque capacity of 88 in/lb for light-to-medium duty drive applications
• Minimum bore diameter of 0.5 inches accommodates standard small-shaft configurations
• 1.5-inch outside diameter and 2.63-inch overall length in a compact form factor
• Part of the ADB series for compatibility with corresponding spider inserts and mating hubs

Compatibility

Designed as an OEM-style replacement or new-installation clamp hub within the LOVEJOY ADB series flexible jaw coupling system. Confirm bore, OD, and series designation against existing coupling components before ordering.

Installation Notes

Installation should be performed by a qualified mechanical technician or millwright. Disconnect and lock out all power to the drive system before handling coupling components. Ensure shaft and bore surfaces are clean and free of burrs before seating the hub. Verify alignment of driving and driven shafts to manufacturer tolerances before final clamp tightening to avoid premature spider wear or hub failure.
