Lovejoy 68514477395 Flexible Screw Hub 1/4 in Bore

Product Description

The LOVEJOY 68514477395 is a flexible screw hub coupling half machined from anodized aluminum. It accepts a minimum bore diameter of 1/4 inch and uses a set screw design to lock onto a shaft. The hub measures 1.12 inches in outside diameter and 1.12 inches in overall length, making it a compact component suited for light-duty power transmission applications. Rated at 17 inch-pounds of torque, it is designed for use in mechanical drive systems where shaft misalignment compensation and vibration dampening are required. Maintenance technicians and mechanical installers typically handle this type of coupling component.

This screw hub is used in flexible coupling assemblies found in HVAC drives, pumps, light industrial equipment, and other rotary power transmission systems. The set screw style allows direct shaft engagement without the need for keyways in all applications, simplifying installation on small-diameter shafts. It is well suited to residential and light commercial mechanical systems where a compact, corrosion-resistant coupling hub is needed.

Key Features

• Anodized aluminum construction provides corrosion resistance and reduced rotating mass
• Set screw design locks directly onto shaft without requiring a separate keyway
• 1/4 inch minimum bore diameter accommodates small-diameter shafts
• 1.12 inch outside diameter and 1.12 inch overall length for compact fitment
• 17 inch-pound torque rating suited to light-duty drive applications

Compatibility

Designed as an OEM-style flexible screw hub for use in standard jaw-type or flexible coupling assemblies requiring a 1/4 inch minimum bore screw hub half.

Installation Notes

Installation is typically performed by a qualified mechanical or HVAC technician. Disconnect and lock out all power to the drive system before removing or installing coupling components. Ensure shaft surfaces are clean and free of burrs before seating the hub, and torque the set screw to the drive manufacturer's specification using the appropriate hex key. Verify shaft alignment after assembly to prevent premature coupling wear.
