Lovejoy 68514477393 Flexible Screw Hub Coupling

Product Description

The LOVEJOY 68514477393 is a flexible screw hub designed for use in mechanical shaft coupling assemblies. This set screw style hub accepts a minimum bore diameter of 0.125 inches and has an outside diameter of 0.75 inches with an overall length of 0.75 inches. Constructed from anodized aluminum, it offers a lightweight, corrosion-resistant body suitable for light-duty power transmission applications. The hub is rated to 5 inch-pounds of torque, making it appropriate for low-torque drive connections in compact machinery, instrumentation, or motion control systems. Licensed mechanical and industrial trades install this component as part of a two-hub flexible coupling assembly.

This hub is used in applications where slight shaft misalignment must be accommodated without transmitting damaging load to connected equipment. Typical installations include small motors, encoders, pumps, and actuators in both commercial and light industrial environments. The anodized aluminum construction keeps overall assembly weight low and resists oxidation in moderate-duty service conditions. The set screw retention style allows for straightforward shaft engagement without requiring specialized tooling beyond a hex key.

Key Features

• Set screw retention style for secure shaft engagement
• Anodized aluminum construction for corrosion resistance and low weight
• Minimum bore diameter of 0.125 inches suits small-diameter shafts
• Outside diameter of 0.75 inches in a compact 0.75-inch overall length
• Rated torque of 5 inch-pounds for light-duty power transmission

Compatibility

Designed as an OEM-style flexible screw hub for use in two-piece flexible coupling assemblies requiring a set screw style hub with a 0.75-inch outside diameter and anodized aluminum construction.

Installation Notes

Installation is typically performed by a licensed millwright, mechanical technician, or qualified industrial maintenance professional. Before installation, de-energize and lock out all power to the connected drive equipment per applicable LOTO procedures. Ensure shaft surfaces are clean and free of burrs before seating the hub. Tighten the set screw with the appropriate hex key to manufacturer specification without exceeding the rated torque capacity of the hub.
