Lovejoy 68514441316 Flexible Coupling Hub 14mm Bore

Product Description

The LOVEJOY 68514441316 is a flexible coupling hub designed for shaft-to-shaft power transmission in mechanical drive systems. With a 14mm maximum bore and a 5mm wide by 2.3mm deep keyway, the hub provides a secure, keyed connection to the drive or driven shaft. The outer diameter measures 1.08 inches and the overall length is 1.72 inches. Constructed from sintered iron, the hub delivers adequate strength and wear resistance for general industrial and HVAC fan and pump drive applications. A complete flexible coupling assembly requires two hubs and one spider insert, ordered separately.

This flexible coupling hub is suited for residential and light commercial mechanical systems where rotational loads must be transmitted between two shafts while absorbing minor misalignment and vibration. Typical applications include HVAC blower assemblies, pump drives, and small motor couplings. The L050 coupling size code designates its series, which helps technicians match the correct spider element and mating hub when assembling or servicing a drive train. The 18000 RPM maximum speed rating makes it suitable for higher-speed motor shaft connections common in fan and blower service.

Key Features

• 14mm maximum bore accommodates standard metric shafts
• 5mm x 2.3mm keyway ensures positive rotational engagement
• 1.08-inch outer diameter and 1.72-inch overall length in a compact form factor
• Sintered iron construction for durability in general drive applications
• Rated to 18000 RPM for high-speed motor and blower shaft use
• L050 coupling size code for straightforward spider and mating hub selection

Compatibility

Designed as an OEM-style replacement or new-installation flexible coupling hub for mechanical drive assemblies using the L050 coupling series. A complete coupling requires two hubs and one spider insert; order components separately to complete the assembly.

Installation Notes

Flexible coupling hubs are installed by licensed mechanics, HVAC technicians, or qualified maintenance personnel. Always disconnect and lock out power to the drive motor before removing or installing coupling components. Ensure the shaft and keyway are clean and free of burrs before pressing or sliding the hub into position. Do not exceed the rated maximum bore or RPM of the coupling series when selecting this hub for a drive application.
