Lovejoy 68514441326 Flexible Coupling Hub 19mm Bore

Product Description

The LOVEJOY 68514441326 is a flexible coupling hub designed for use in power transmission applications requiring a keyed shaft connection. With a 19mm maximum bore and a 6mm x 2.8mm keyway (width x depth), this hub accepts standard keyed shafts and transmits torque while accommodating minor shaft misalignment. The hub measures 2.11 inches in outer diameter and 2.5 inches in overall length, and is constructed from sintered iron for durability in industrial and mechanical service environments. Two hubs and one spider insert are required to form a complete flexible coupling assembly. Licensed HVAC, mechanical, and industrial technicians regularly specify this style of hub for motor-to-pump and motor-to-compressor drive trains.

This coupling hub is suited for residential and light commercial mechanical systems, as well as industrial drive applications where flexible jaw-type couplings are standard practice. Typical installations include pump drives, fan assemblies, compressor connections, and general power transmission setups operating within the rated speed range. The sintered iron construction makes it appropriate for moderate-load, indoor mechanical applications. Complete coupling assemblies require ordering two hubs and one spider insert separately.

Key Features

• 19mm maximum bore accommodates standard keyed shafts up to that diameter
• 6mm x 2.8mm keyway (width x depth) for positive torque transmission
• 2.11 inches outer diameter and 2.5 inches overall length for compact installation
• Sintered iron construction provides durability in mechanical drive applications
• Rated up to 9000 RPM for compatibility with high-speed motor shafts
• Coupling Size Code L095 for cross-reference and spider selection

Compatibility

This hub carries Coupling Size Code L095 and is compatible with L095-series jaw coupling spiders. Two hubs plus one spider insert are required to complete the coupling assembly. Confirm bore size, keyway dimensions, and coupling size code when selecting mating components.

Installation Notes

Flexible coupling hubs are typically installed by mechanical contractors, millwrights, or qualified technicians familiar with power transmission equipment. Disconnect and lock out all power to connected motors and driven equipment before beginning installation or removal. Verify shaft diameter, keyway dimensions, and coupling alignment before securing the hub to the shaft. Do not exceed the rated maximum speed of 9000 RPM in service.
