Lovejoy 68514441462 Flexible Coupling Hub 19mm Bore

Product Description

The LOVEJOY 68514441462 is a flexible coupling hub designed for use in power transmission assemblies where shaft misalignment tolerance and vibration dampening are required. Manufactured from sintered iron, this hub features a 19mm maximum bore and a 6mm wide by 2.8mm deep keyway for secure shaft engagement. It measures 2.11 inches in outer diameter and 2.12 inches in overall length. Rated for up to 9000 RPM, it suits demanding industrial and mechanical drive applications. Note that a complete jaw-style flexible coupling requires two hubs and one spider insert, each ordered separately.

This flexible coupling hub is suited for mechanical power transmission installations in HVAC equipment, pumps, compressors, and general industrial machinery where shaft coupling is needed between a motor and a driven load. The L090 coupling size code identifies its series fitment. It is appropriate for both light commercial and industrial service environments where sintered iron construction provides adequate strength and wear resistance. Installers assembling a complete coupling unit must source two hubs and one elastomeric spider to complete the assembly.

Key Features

• 19mm maximum bore accommodates a range of shaft sizes up to that diameter
• 6mm x 2.8mm keyway provides positive rotational drive engagement
• Sintered iron construction offers solid strength with consistent dimensional tolerance
• Rated to 9000 RPM for high-speed drive applications
• L090 coupling size code for series identification and component matching
• Sold individually — order two hubs and one spider for a complete coupling assembly

Compatibility

Designed for use in L090 series jaw-style flexible coupling assemblies. A complete coupling requires two hubs of matching bore size and one spider insert ordered separately. Verify bore, keyway, and coupling size code when selecting mating components.

Installation Notes

Installation is typically performed by a millwright, mechanical technician, or HVAC technician during motor or drive train service. De-energize and lock out all power to the equipment before removing or installing coupling components. Ensure shaft and bore surfaces are clean and free of burrs before pressing or sliding the hub onto the shaft. Confirm keyway and set screw engagement are secure before returning the drive to service.
