Lovejoy 68514441464 Flexible Coupling Hub 25mm Bore

Product Description

The LOVEJOY 68514441464 is a flexible coupling hub designed for use in mechanical power transmission systems. It accepts a maximum bore of 25mm and includes an 8mm wide by 3.3mm deep keyway for positive shaft engagement. The hub measures 2.11 inches in outer diameter and 2.12 inches in overall length, and is constructed from sintered iron for durability under rotational load. Rated to 9,000 RPM, this hub suits high-cycle industrial and commercial drive applications. Two hubs and one spider element are required to form a complete flexible coupling assembly. Mechanical technicians and industrial service professionals install this component as part of motor-to-load coupling systems.

This coupling hub is used in applications where shaft misalignment absorption and vibration dampening are needed between a driver and driven component. Typical installations include pump drives, compressor drives, conveyor systems, and other rotating equipment found in commercial HVAC, industrial, and mechanical service environments. The sintered iron construction handles the torsional demands of continuous-duty operation. Because two hubs and one spider are required for a complete coupling, confirm the mating hub size code matches before ordering.

Key Features

• 25mm maximum bore accommodates a range of shaft diameters
• 8mm x 3.3mm keyway provides positive rotational engagement
• 2.11-inch OD and 2.12-inch overall length in a compact profile
• Sintered iron construction for strength and wear resistance
• Rated to 9,000 RPM for high-speed drive applications
• Coupling Size Code L090 for hub-to-hub and spider compatibility reference

Compatibility

Designed for use with the L090 coupling size family. Two hubs of matching size code and one compatible spider element are required to complete the assembly. Verify bore, keyway dimensions, and size code against the mating hub and spider before installation.

Installation Notes

Installation is performed by qualified mechanical or industrial service technicians. De-energize and lock out all power to the drive system before removing or installing coupling components, following applicable LOTO procedures. Ensure shaft and bore dimensions are within tolerance before pressing or sliding the hub into position. Do not operate the coupling assembly without the spider element seated between both hubs.
