Lovejoy 68514441318 Flexible Coupling Hub 16mm Bore

Product Description

The LOVEJOY 68514441318 is a flexible coupling hub designed for use in power transmission applications requiring precise shaft-to-shaft torque transfer with vibration dampening. This hub accepts a maximum bore of 16mm and features a 5mm wide by 2.3mm deep keyway for positive rotational drive engagement. The outer diameter measures 1.36 inches and the overall length is 2 inches. Constructed from sintered iron, it offers adequate strength and wear resistance for moderate-load coupling service. Note that a complete flexible coupling assembly requires two hubs plus one spider element, each ordered separately.

This hub is suited for light-to-medium industrial drive applications including pumps, compressors, fans, and general rotating equipment found in HVAC, refrigeration, and mechanical systems. The jaw-style flexible coupling design accommodates minor shaft misalignment and reduces shock load transmission between driver and driven components. It is typically installed by mechanical contractors, millwrights, or HVAC technicians performing motor or pump replacements where the original coupling hub is worn or damaged.

Key Features

• 16mm maximum bore with 5mm x 2.3mm keyway for positive shaft engagement
• 1.36 inches outer diameter and 2 inches overall length for compact installation
• Sintered iron construction for durable wear resistance in drive applications
• Rated up to 14,000 RPM for high-speed motor and pump service
• Coupling Size Code L070 for cross-reference and spider selection
• Sold individually — order two hubs and one spider for a complete coupling assembly

Compatibility

This hub carries Coupling Size Code L070 and is compatible with L070-series flexible coupling spiders. Designed as a jaw-type flexible coupling hub for industrial and HVAC rotating equipment drive trains where a 16mm bore and L070 series coupling are specified.

Installation Notes

Installation should be performed by a qualified technician. Disconnect and lock out all power to the motor or drive equipment before beginning work. Press or slide the hub onto the shaft to the recommended engagement depth and secure via the keyway; do not strike the hub face with a hard hammer as this can damage the sintered iron bore. Verify shaft alignment within the coupling manufacturer's specified tolerance before returning the equipment to service, and confirm the correct spider element is selected to complete the L070 assembly.
