Lovejoy 68514436164 Flexible Coupling Hub 2in Bore

Product Description

The LOVEJOY 68514436164 is a flexible coupling hub designed for power transmission applications in mechanical and industrial systems. This cast iron hub accepts a maximum bore diameter of 2 inches and features a 1/2-inch by 1/4-inch keyway for secure shaft engagement. With an outer diameter of 6.35 inches and an overall length of 5.06 inches, it provides a robust connection point in flexible coupling assemblies. Rated to 3,750 RPM, it suits a wide range of rotary equipment. Licensed mechanical trades and industrial maintenance professionals typically source this component for motor-to-load coupling setups requiring flexibility and vibration damping.

This flexible coupling hub is suited for use in industrial machinery, pump drives, compressor systems, and other rotating equipment where misalignment compensation is required. The cast iron construction holds up in demanding mechanical environments. It is used as one half of a complete flexible coupling assembly and pairs with a mating hub and a flexible element or spider insert to complete the drive connection. Packaging quantity is one hub per unit.

Key Features

• Maximum bore diameter of 2 inches for compatibility with common shaft sizes
• 1/2-inch by 1/4-inch keyway width and depth for positive shaft locking
• 6.35-inch outer diameter and 5.06-inch overall length for size-9S coupling assemblies
• Rated to 3,750 RPM for medium-speed rotating equipment
• Cast iron construction for durability in industrial environments
• Coupling size code 9S for straightforward replacement identification

Compatibility

Designed as an OEM-style replacement flexible coupling hub for size-9S coupling assemblies used in industrial power transmission applications.

Installation Notes

Installation is performed by qualified mechanical or industrial maintenance technicians. De-energize and lock out the drive motor before mounting or removing any coupling component. Ensure the shaft and bore are clean and free of burrs before pressing or sliding the hub into position. Verify that the mating hub and flexible element are also sized for a 9S coupling assembly before completing the drive connection.
