Lovejoy 68514456628 Flexible Clamp Hub Anodized Aluminum

Product Description

The LOVEJOY 68514456628 is a flexible clamp hub designed for use in shaft coupling assemblies requiring precise, low-backlash torque transmission. Built from anodized aluminum, this hub accepts a minimum bore diameter of 3/16 inches and measures 0.75 inches in outside diameter with an overall length of 0.9 inches. It is part of the EC050 series and follows a clamp-style clamping method for secure shaft retention. Rated at 5 in/lb of torque, this compact hub suits light-duty coupling applications in mechanical, HVAC, and industrial drive systems. Installation is typically performed by mechanical technicians or maintenance professionals working on small-bore shaft assemblies.

This hub is suited for light-duty flexible coupling assemblies in residential and commercial mechanical systems. The EC050 series clamp hub is used in applications where a compact, corrosion-resistant aluminum hub is needed to connect small-diameter shafts with minimal assembly footprint. Its clamp-style design allows for straightforward shaft engagement without set screws, making it a practical choice for controlled-torque drive connections in tight spaces.

Key Features

• Anodized aluminum construction for corrosion resistance in light-duty environments
• Clamp-style hub design for secure, set-screw-free shaft retention
• Minimum bore diameter of 3/16 inches for small-shaft applications
• 0.75 inch outside diameter and 0.9 inch overall length for compact fitment
• Rated at 5 in/lb torque capacity for light-duty coupling use
• Part of the EC050 series with coupling size code ES075

Compatibility

Designed as an OEM-style replacement or component-level addition for EC050 series flexible coupling assemblies requiring a clamp-style hub with a 3/16 inch minimum bore and 0.75 inch outside diameter.

Installation Notes

Installation is performed by qualified mechanical or maintenance technicians working on small-bore shaft drive assemblies. Power down and lock out all connected equipment before removing or installing any coupling components. Verify shaft diameter falls within the specified bore range before assembly, and ensure the hub is fully seated and the clamp fastener is torqued per the coupling assembly manufacturer guidelines. Do not exceed the rated torque capacity of 5 in/lb for this hub.
