Lovejoy 68514441467 Flexible Coupling Hub 20mm Bore

Product Description

The LOVEJOY 68514441467 is a flexible coupling hub designed for use in mechanical power transmission applications. With a 20mm maximum bore and a 6mm wide by 2.8mm deep keyway, this hub accepts keyed shafts and transfers torque between a driver and driven component while accommodating minor misalignment. The hub measures 2.11 inches in outer diameter and 2.5 inches overall length, and is constructed from sintered iron for durability in industrial service. A complete flexible coupling assembly requires two hubs and one spider insert, ordered separately. This hub is installed by licensed mechanics and millwrights in pump, compressor, conveyor, and similar rotating equipment setups.

This flexible coupling hub is suited for light-to-medium duty industrial and commercial machinery where shaft-to-shaft connection with misalignment tolerance is required. Common applications include HVAC equipment drives, pump sets, fans, and general mechanical power transmission assemblies. The sintered iron construction handles the demands of continuous-duty rotating service. The coupling size code is L095, and the hub is rated for operation up to 9000 RPM, making it appropriate for higher-speed equipment where vibration isolation between shafts is necessary.

Key Features

• 20mm maximum bore accommodates standard metric shaft diameters
• 6mm x 2.8mm keyway secures the hub to keyed shafts for positive torque transfer
• 2.11-inch outer diameter and 2.5-inch overall length in a compact form factor
• Sintered iron construction provides wear resistance in continuous-duty rotating service
• Rated up to 9000 RPM for compatibility with higher-speed drive applications
• Order two hubs and one spider insert for a complete flexible coupling assembly

Compatibility

This hub carries coupling size code L095. A complete flexible coupling assembly requires two of these hubs paired with one compatible spider insert. Designed as an OEM-style replacement or new-installation component for L095-series jaw-type flexible coupling assemblies.

Installation Notes

Installation is typically performed by a qualified mechanic or millwright. Shut down and lock out all power to the drive system before beginning any coupling work, following applicable LOTO procedures. Ensure the bore and keyway are clean and free of burrs before pressing or sliding the hub onto the shaft. Do not exceed the rated maximum bore diameter when machining the hub, and verify shaft and hub alignment before placing the equipment back in service.
