Lovejoy 68514456644 Flexible Clamp Hub 3/8 in Bore EC050

Product Description

The LOVEJOY 68514456644 is a flexible clamp hub designed for use in mechanical coupling assemblies. It connects rotating shafts and transmits torque while accommodating minor misalignment between coupled components. Constructed from anodized aluminum, this hub offers a lightweight build with corrosion resistance suitable for general industrial and mechanical service environments. Key specifications include a minimum bore diameter of 3/8 inches, an outside diameter of 1 inch, an overall length of 1.25 inches, and a rated torque capacity of 11 inch-pounds. The clamp-style retention secures the hub to the shaft without requiring a keyway, simplifying installation and removal.

This clamp hub is suited for use in light-duty power transmission applications such as motor-to-pump connections, fan drives, and equipment found in HVAC, refrigeration, and general mechanical systems. The EC050 series designation identifies it as part of a standardized flexible coupling family, and the coupling size code ES100 indicates the corresponding element size for proper mating. Mechanical technicians and equipment service professionals typically install this component during coupling assembly replacements or new equipment builds.

Key Features

• Anodized aluminum construction provides lightweight build and corrosion resistance
• Clamp-style hub design allows shaft attachment without a keyway
• 3/8 inch minimum bore diameter fits common small-diameter shaft applications
• 1 inch outside diameter with 1.25 inch overall length for compact installation footprint
• Rated torque of 11 inch-pounds suits light-duty power transmission service
• EC050 series compatibility with ES100 coupling size code for matched element selection

Compatibility

Designed as an OEM-style replacement or new-installation component for flexible coupling assemblies in the EC050 series using the ES100 element size designation.

Installation Notes

Installation is typically performed by a qualified mechanical technician. Disconnect and lock out all power to the equipment before beginning any coupling service. Inspect the shaft surface for burrs or contamination before seating the hub, and confirm bore and shaft dimensions match before final installation. Follow all applicable machinery safety standards and equipment manufacturer guidelines during assembly.
