Lovejoy 68514456618 Flexible Screw Coupling Hub

Product Description

The LOVEJOY 68514456618 is a flexible screw-type coupling hub machined from anodized aluminum. It serves as the shaft-interface component in a flexible coupling assembly, transmitting torque between connected shafts while accommodating minor misalignment. With a minimum bore diameter of 0.125 inches, an outside diameter of 0.5 inches, and an overall length of 0.5 inches, this hub is sized for small-bore drive applications. A set screw secures the hub to the shaft. The anodized aluminum construction keeps weight minimal at 0.01 pounds while providing a corrosion-resistant surface. Licensed mechanics, millwrights, and HVAC technicians working on small motor and drive assemblies are the primary installers.

This coupling hub is suited for light-duty, small-bore shaft connections found in compact motor drives, fan assemblies, pump drives, and instrumentation equipment. Its set screw style makes it appropriate for applications where quick shaft engagement and low rotating mass are priorities. The rated torque capacity of 2.00 inch-pounds fits low-torque drive trains common in residential and light commercial HVAC blower motor assemblies and similar small equipment.

Key Features

• Set screw style engagement for straightforward shaft installation and removal
• Anodized aluminum construction for corrosion resistance and reduced rotating mass
• Minimum bore diameter of 0.125 inches for small-shaft compatibility
• Compact 0.5 inch outside diameter and 0.5 inch overall length for tight-clearance installations
• Rated torque of 2.00 inch-pounds for light-duty drive applications

Compatibility

Designed as an OEM-style flexible screw coupling hub for small-bore shaft applications requiring a set screw style hub with a 0.125 inch minimum bore diameter and 0.5 inch outside diameter.

Installation Notes

Installation is typically performed by a millwright, mechanical technician, or qualified HVAC service tech. De-energize and lock out the equipment before installing or removing the hub. Ensure the shaft is clean and free of burrs before seating the hub. Tighten the set screw to the coupling manufacturer's specified torque range using the correct hex key; do not overtighten, as this can deform the bore on an aluminum hub.
