Lovejoy 68514456638 Flexible Screw Coupling Hub 3/8 Inch

Product Description

The LOVEJOY 68514456638 is a flexible screw coupling hub machined from anodized aluminum and designed for use in mechanical power transmission systems. This set screw style hub accepts a minimum bore diameter of 3/8 inches and measures 1 inch in outside diameter with an overall length of 1 inch. The anodized finish improves corrosion resistance and surface hardness without adding significant mass — the hub weighs just 0.07 pounds. It is rated for up to 11 inch-pounds of torque, making it suited for light-duty shaft coupling applications. Mechanical and industrial maintenance technicians typically handle installation of this component.

This hub is part of the EC050 series and carries a coupling size code of ES100. It is intended for use in flexible coupling assemblies where vibration dampening and minor shaft misalignment compensation are required. Typical applications include small motors, pumps, and light industrial drive systems. The set screw fastening style allows for straightforward installation on standard shaft diameters starting at 3/8 inches. Its compact profile fits where space is limited.

Key Features

• Anodized aluminum construction for corrosion resistance and reduced weight
• Set screw style fastening for direct shaft engagement
• 3/8 inch minimum bore diameter
• 1 inch outside diameter and 1 inch overall length for compact fitment
• Rated to 11 inch-pounds of torque
• Part of the EC050 series, size code ES100

Compatibility

Designed as an OEM-style replacement or direct-fit hub for flexible screw coupling assemblies in the EC050 series. Specific mating coupling components should be verified by series and size code prior to installation.

Installation Notes

Installation should be performed by a qualified mechanical technician. Ensure the drive system is fully de-energized and locked out before handling any shaft coupling components. Use properly sized set screw tooling and verify shaft diameter falls within the hub bore specification before mounting. Do not exceed the rated torque capacity of 11 inch-pounds during operation.
