Lovejoy 68514441453 Flexible Coupling Hub 11mm Bore

Product Description

The LOVEJOY 68514441453 is a flexible coupling hub designed for use in power transmission applications where shaft misalignment compensation and vibration dampening are required. This hub features an 11mm maximum bore with a 4mm wide by 1.8mm deep keyway, a 1.36-inch outer diameter, and an overall length of 2 inches. Constructed from sintered iron, it offers reliable strength and wear resistance for industrial and mechanical drive applications. A complete flexible coupling assembly requires two hubs and one spider insert, each ordered separately.

This coupling hub is suited for light-to-medium duty power transmission setups in industrial machinery, pumps, compressors, and mechanical drive systems. It is commonly installed by millwrights, maintenance technicians, and mechanical contractors working on equipment requiring flexible shaft-to-shaft connections. The compact dimensions make it appropriate for space-constrained drive train configurations. Always order two hubs and one spider to complete the assembly.

Key Features

• 11mm maximum bore accommodates standard metric shafts
• 4mm x 1.8mm keyway for positive rotational drive engagement
• 1.36-inch outer diameter and 2-inch overall length for compact fitment
• Sintered iron construction for durability and wear resistance
• Rated up to 14,000 RPM for high-speed drive applications
• Coupling Size Code L070 for cross-reference and spider selection

Compatibility

Designed for use in flexible jaw-type coupling assemblies with Coupling Size Code L070. Two hubs and one spider insert are required to complete a full coupling assembly; spider must be ordered separately and matched to the L070 size code.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician. Disconnect and lock out all power sources before handling shaft components. Ensure shaft and bore dimensions are verified prior to pressing or sliding the hub onto the shaft. Do not exceed the rated maximum RPM, and confirm spider element material is appropriate for the operating load and environment before final assembly.
