Lovejoy 68514456630 Flexible Clamp Hub Anodized Aluminum

Product Description

The LOVEJOY 68514456630 is a flexible clamp hub designed for use in flexible shaft coupling assemblies. It is part of the EC050 series and features a clamp-style locking mechanism that secures to the shaft without set screws, distributing clamping force evenly around the bore. The hub is machined from anodized aluminum, keeping rotating weight low while providing corrosion resistance. Key dimensions are a 3/16 inch minimum bore diameter, a 0.75 inch outside diameter, and an overall length of 0.9 inches. Rated torque capacity is 5 in-lb. The part weighs approximately 0.03 pounds. Coupling size code is ES075.

This clamp hub is intended for light-duty power transmission applications where precise shaft coupling is required. Typical installation scenarios include small motors, encoders, servo drives, pumps, and instrumentation equipment found in industrial, HVAC controls, and mechanical systems. The clamp-style design makes it well suited for applications requiring frequent disassembly or where shaft marking from set screws is not acceptable. The anodized aluminum construction is appropriate for indoor and light-duty environments where weight savings matter.

Key Features

• Clamp-style hub design provides even shaft clamping without set screws
• Anodized aluminum construction reduces rotating mass and resists corrosion
• 3/16 inch minimum bore diameter accommodates small-diameter shafts
• 0.75 inch outside diameter in a compact 0.9 inch overall length
• Rated torque capacity of 5 in-lb for light-duty power transmission
• Part of the EC050 series for use with compatible flexible coupling elements

Compatibility

Designed for use as a clamp hub component within the LOVEJOY EC050 series flexible coupling system. Coupling size code ES075. Compatible coupling elements and companion hubs should match the EC050 series designation.

Installation Notes

Installation is typically performed by a mechanical technician or qualified maintenance professional. De-energize and lock out all connected equipment before installing or removing the hub. Ensure shaft and bore surfaces are clean and free of burrs before assembly. Tighten clamp fasteners evenly and verify alignment of mating coupling components before returning the system to service.
