Lovejoy 68514456652 Flexible Clamp Hub 3/8 in Ec Series

Product Description

The LOVEJOY 68514456652 is a flexible clamp-style coupling hub designed to connect rotating shafts in mechanical drive systems. Machined from anodized aluminum, this hub accepts a minimum bore diameter of 3/8 inches and measures 1.12 inches in outside diameter with an overall length of 1.5 inches. It carries a rated torque of 17 inch-pounds, making it appropriate for light-duty power transmission applications. The EC Series designation identifies the coupling size code as ES112. Installers working on HVAC equipment, pump assemblies, or small motor drives will recognize this as a standard clamp-hub component used to join drive shafts while accommodating minor misalignment.

This clamp hub is suited for residential and light commercial mechanical systems where compact, lightweight drive couplings are required. Typical applications include fan shaft assemblies, pump drives, and small motor-to-load connections in HVAC and plumbing equipment rooms. The anodized aluminum construction keeps weight low at 0.12 pounds while providing corrosion resistance in indoor mechanical environments. This hub is sold individually and is intended for use as part of a complete EC Series flexible coupling assembly.

Key Features

• Anodized aluminum construction for corrosion resistance and reduced weight
• Clamp-hub style mounting for secure shaft engagement without set-screw damage

• Compact profile: 1.12 inches OD x 1.5 inches OAL
• EC Series, size code ES112 for straightforward coupling selection
• Minimum bore diameter of 3/8 inches suits small-diameter drive shafts

Compatibility

Designed for use within the LOVEJOY EC Series flexible coupling system, size code ES112. Consult EC Series coupling documentation to confirm mating spider and hub compatibility before installation.

Installation Notes

Installation is typically performed by a millwright, HVAC mechanic, or qualified maintenance technician. De-energize and lock out all power to the drive system before removing or installing any coupling component. Ensure shaft and bore surfaces are clean and free of burrs before seating the hub. Verify torque rating is appropriate for the driven load before commissioning the assembly.
