Lovejoy 68514456620 Flexible Clamp Hub EC050 Aluminum

Product Description

The LOVEJOY 68514456620 is a clamp-style flexible coupling hub designed for light-duty shaft connection applications in mechanical drive systems. Built from anodized aluminum, this hub offers corrosion resistance in a compact, low-mass form factor. It measures 0.5 inches in outside diameter and 0.75 inches in overall length, with a minimum bore diameter of 0.125 inches. Rated at 2 in/lb of torque, it is suited for small motion control assemblies, instrumentation drives, and light power-transmission setups. The clamp-style design provides secure shaft engagement without the need for keyways or set screws, simplifying both installation and removal. Mechanical technicians and industrial maintenance personnel are the typical installers for this component.

This hub belongs to the EC050 coupling series and is intended for use in compact, low-torque shaft coupling assemblies. Typical applications include encoder connections, small motor-to-shaft couplings, and precision instrument drive trains where minimal shaft loading and easy repositioning are required. The anodized aluminum construction keeps rotating mass low, making it a practical choice in motion control and servo applications where inertia is a consideration.

• Anodized aluminum construction for corrosion resistance and low rotating mass
• Compact form factor: 0.5 inches OD and 0.75 inches overall length
• Minimum bore diameter of 0.125 inches suits small-diameter shafts
• Rated torque of 2 in/lb appropriate for light motion control and instrumentation drives
• Part of the EC050 series for standardized coupling assembly compatibility

Compatibility

Designed as an OEM-style replacement or new-installation hub within the LOVEJOY EC050 flexible coupling series. Consult the EC050 series coupling specifications to confirm bore, torque, and dimensional fit before installation.

Installation Notes

Installation is performed by mechanical technicians or industrial maintenance personnel familiar with shaft coupling assemblies. Disengage and lock out all power to the drive system before handling any coupling components. Verify shaft diameter falls within the bore range of the hub before tightening the clamp fastener. Do not exceed the rated torque of 2 in/lb during shaft engagement, as over-clamping can deform the aluminum hub bore.
