Lovejoy 68514456624 Flexible Screw Coupling Hub

Product Description

The LOVEJOY 68514456624 is a flexible screw coupling hub machined from anodized aluminum, designed to connect rotating shafts in mechanical drive systems. It uses a set screw fastening style to secure the hub to the shaft bore. With a minimum bore diameter of 3/16 inches and an outside diameter of 0.75 inches, this compact hub fits tight-clearance applications where space is limited. At a rated torque of 5.00 inch-pounds, it suits light-duty power transmission needs. Maintenance technicians and mechanical assemblers typically install this component in small motors, pumps, and instrumentation drives.

This hub is suited for light industrial, HVAC auxiliary, and instrumentation applications where a compact, corrosion-resistant coupling component is required. The anodized aluminum construction reduces weight while providing surface hardness that resists wear in indoor mechanical assemblies. It is sold individually and is appropriate for use wherever a standard screw-type flexible coupling hub with a 3/16 inch bore is specified.

Key Features

• Anodized aluminum construction for lightweight, corrosion-resistant performance
• Set screw fastening style for secure shaft retention without additional hardware
• 3/16 inch minimum bore diameter accommodates small-diameter shafts
• 0.75 inch outside diameter and 0.75 inch overall length for compact fitment
• Rated to 5.00 inch-pounds torque for light-duty drive applications

Compatibility

Designed as an OEM-style flexible screw coupling hub for light-duty mechanical drive systems requiring a 3/16 inch bore and 0.75 inch outside diameter hub component.

Installation Notes

Installation is typically performed by mechanical technicians or millwrights. De-energize and lock out the drive motor before servicing any coupling components per applicable LOTO procedures. Align shafts carefully before tightening the set screw to avoid premature wear on the hub bore. Verify that the shaft diameter matches the specified bore before installation.
