Lovejoy 68514456654 Flexible Screw Hub 3/8 in Bore

Product Description

The LOVEJOY 68514456654 is a flexible screw hub coupling designed for use in mechanical power transmission applications. This set-screw style hub is machined from anodized aluminum, offering corrosion resistance with a lightweight profile. It accepts a minimum bore diameter of 3/8 inch and measures 1.12 inches in outside diameter with an overall length of 1.5 inches. Rated at 17 inch-pounds of torque, this hub is sized for light-duty coupling assemblies and is part of the EC050 series. Installation is typically handled by mechanical technicians and millwrights working on pump drives, conveyor systems, and other rotating equipment.

This coupling hub is suited for residential and light commercial mechanical systems where a compact, corrosion-resistant hub is required. The EC050 series design makes it appropriate for use in pump-to-motor connections, fan shaft assemblies, and similar low-to-moderate torque drive applications. The anodized aluminum construction is well suited for environments where moisture or mild chemical exposure is a concern. The set-screw attachment style provides a secure, direct connection to the shaft without requiring additional hardware beyond standard hex key tooling.

Key Features

• Anodized aluminum construction for corrosion resistance and reduced weight
• Set screw attachment style for straightforward shaft installation
• Minimum bore diameter of 3/8 inch for compatibility with small-diameter shafts
• 1.12 inch outside diameter fits compact coupling envelopes
• 17 inch-pounds torque rating for light-duty drive applications
• Part of the EC050 series, size code ES112

Compatibility

Designed as an OEM-style replacement or aftermarket screw hub coupling for light-duty mechanical drive assemblies requiring a 3/8 inch minimum bore and EC050 series fitment.

Installation Notes

Power down and de-energize all rotating equipment before servicing coupling assemblies. Align shafts within manufacturer-recommended tolerances before tightening set screws. A standard hex key is required to secure the set screw against the shaft. Follow applicable machinery safety standards and lockout/tagout procedures during installation and removal.
