Lovejoy 68514441317 Flexible Coupling Hub 14mm Bore

Product Description

The LOVEJOY 68514441317 is a flexible coupling hub designed for use in mechanical power transmission systems. This sintered iron hub accepts a maximum bore of 14mm and features a keyway measuring 5mm wide by 2.3mm deep for positive shaft engagement. With an outer diameter of 1.36 inches and an overall length of 2 inches, it fits into compact drive configurations where precise shaft alignment and torque transfer are required. Licensed mechanics and equipment technicians use this hub in pumps, fans, compressors, and general industrial drive trains. One complete flexible coupling requires two hubs and one spider insert, ordered separately.

This coupling hub is suited for light- to medium-duty power transmission applications across industrial and commercial equipment. Typical installations include motor-to-pump drives, HVAC equipment shaft couplings, and conveyor or fan drive systems where some degree of angular or parallel misalignment must be accommodated. The sintered iron construction provides adequate strength for shaft speeds up to 14,000 RPM, making it viable for high-speed motor applications. The L070 coupling size code designates the specific jaw geometry and spider compatibility within the LOVEJOY L-series jaw coupling family.

Key Features

• 14mm maximum bore accommodates a range of metric shaft diameters
• 5mm x 2.3mm keyway ensures positive, slip-resistant shaft connection
• Sintered iron construction offers durability in industrial drive environments
• Rated to 14,000 RPM for compatibility with high-speed motor applications
• Compact profile at 1.36 inches OD and 2 inches overall length
• L070 size code — order two hubs and one spider for a complete coupling assembly

Compatibility

This hub corresponds to LOVEJOY L070 series jaw coupling components. A complete coupling assembly requires two hubs (this part) and one separately ordered spider insert sized for the L070 series. No additional specific compatible model or system data was provided in the product input.

Installation Notes

Installation is typically performed by a millwright, mechanic, or equipment technician. Disconnect and lock out all power to the drive system before installing or servicing any coupling component. Ensure shaft and bore dimensions are confirmed before pressing or securing the hub, and verify keyway and key stock dimensions match before final assembly. Do not exceed the rated maximum RPM, and align shafts within the tolerance limits specified for jaw-style flexible couplings.
