Lovejoy 68514411743 Flexible Coupling Hub L110 Sintered Iron

Product Description

The LOVEJOY 68514411743 is a flexible coupling hub designed for use in mechanical power transmission assemblies. Built from sintered iron, this L110 series hub accepts a 1.25-inch bore and measures 4.25 inches in overall length with a 3.31-inch outside diameter. It is engineered to connect rotating shafts in industrial drive systems, providing the interface between two shaft ends when paired with the appropriate spider element. One complete coupling assembly requires two hubs and one spider, which must be ordered separately. Licensed industrial mechanics and millwrights are the primary installers for components of this type.

This hub is suited for industrial machinery, conveyor drives, pump drives, compressor drives, and other shaft coupling applications where L110 series flexible couplings are specified. The L110 coupling size is a widely used standard in light-to-medium duty power transmission. The keyway dimensions and bore diameter make this hub compatible with standard keyed shafts in rotating equipment found in commercial and industrial environments.

Key Features

• Sintered iron construction for durability in industrial drive environments
• 1.25-inch bore diameter accommodates standard keyed shaft sizes
• L110 series designation for direct series-matched hub and spider selection
• Keyway dimensions: 1/4-inch width, 1/8-inch depth for standard key stock
• Rated to 792 in-lb torque capacity with a maximum speed of 5,000 RPM
• Two hubs and one spider required for a complete coupling assembly

Compatibility

Designed as an OEM-style replacement or new-installation hub within the L110 flexible coupling series. A complete coupling requires two L110 series hubs and one L110 spider element, ordered separately.

Installation Notes

Installation should be performed by a qualified millwright or industrial mechanic familiar with shaft coupling procedures. Disconnect and lock out all power to the drive system before handling any coupling components. Ensure shaft and bore surfaces are clean and free of burrs before pressing or sliding the hub into position. Follow applicable ANSI and OSHA machine guarding requirements when coupling guards are reinstalled after service.
