Lovejoy 68514441314 Flexible Coupling Hub 11mm Bore

Product Description

The LOVEJOY 68514441314 is a flexible coupling hub designed for use in mechanical power transmission applications. This sintered iron hub features an 11mm maximum bore and a 4mm x 1.8mm keyway (width x depth), providing a secure keyed shaft connection. The hub measures 1.08 inches in outer diameter and 1.72 inches in overall length. It is rated for speeds up to 18,000 RPM, making it suitable for demanding rotational equipment. This is a single hub component — a complete flexible coupling assembly requires two hubs and one spider insert, ordered separately.

This flexible coupling hub is used in industrial and commercial mechanical drive systems where shaft misalignment compensation and vibration damping are required. Typical applications include pumps, compressors, fans, and motor-driven equipment across HVAC, manufacturing, and process industries. The L050 coupling size code identifies the correct spider and mating hub for assembly. Licensed mechanics and equipment technicians typically install and service these components during equipment builds or drivetrain maintenance.

Key Features

• 11mm maximum bore with 4mm x 1.8mm keyway for secure keyed shaft engagement
• Sintered iron construction for durability in mechanical drive environments
• Rated to 18,000 RPM for high-speed applications
• Coupling size code L050 for correct spider and hub matching
• 1.08 inch OD and 1.72 inch overall length compact profile
• Sold as a single hub — order two hubs and one spider for a complete coupling assembly

Compatibility

Designed for use with LOVEJOY L050 series flexible coupling spiders and mating hubs. A complete coupling requires two hubs and one spider insert. Verify bore size, keyway dimensions, and coupling size code before ordering.

Installation Notes

Power down and lock out all equipment before servicing any coupling or drivetrain component. Ensure shaft diameter and keyway dimensions match the hub bore and keyway specifications prior to installation. A complete flexible coupling assembly requires two hubs and one appropriately rated spider — do not operate an incomplete assembly. Coupling installation should be performed by a qualified mechanic following the equipment manufacturer's alignment and assembly procedures.
