Lovejoy 68514476843 Flexible Clamp Hub 3/8 in Bore Adb

Product Description

The LOVEJOY 68514476843 is a flexible clamp hub designed for use in mechanical power transmission couplings. Part of the ADB series, it features a clamp-style design that secures to a shaft with a minimum bore diameter of 3/8 inches. The hub measures 1 inch in outside diameter and 1.5 inches in overall length, making it a compact component suited for tight drive train assemblies. Constructed from anodized aluminum, it offers corrosion resistance at a low weight of 0.1 pounds. It is rated for up to 20 inch-pounds of torque. Mechanical technicians and millwrights install this component as part of flexible coupling assemblies in HVAC, industrial, and light mechanical drive systems.

This clamp hub is used in applications where a flexible coupling is required to connect two shafts in residential or light commercial mechanical systems. The ADB series clamp-style hub accommodates minor shaft misalignment while transmitting torque reliably. Its anodized aluminum construction suits indoor drive applications where weight savings and corrosion resistance are priorities. It is commonly found in fan drives, pump assemblies, and other rotary power transmission setups where compact coupling geometry is needed.

Key Features

• Clamp-style hub design for secure, tool-accessible shaft attachment
• Anodized aluminum construction provides corrosion resistance at low weight
• 3/8 inch minimum bore diameter suits small-shaft drive assemblies
• 1.5 inch overall length and 1 inch outside diameter for compact fitment
• Rated to 20 inch-pounds torque capacity
• ADB series coupling size code ADB5 for straightforward replacement sourcing

Compatibility

Designed as an OEM-style replacement clamp hub for flexible coupling assemblies requiring a 3/8 inch bore, 1 inch OD component within the LOVEJOY ADB series.

Installation Notes

Installation of clamp hubs is typically performed by mechanical technicians or millwrights. De-energize and lock out the drive system before beginning any coupling work in accordance with OSHA lockout/tagout procedures. Ensure shaft surfaces are clean and free of burrs before seating the hub. Do not exceed the rated torque of 20 inch-pounds when tightening the clamp fastener.
