Lovejoy 68514436175 Flexible Coupling Hub 1-5/8 in Bore

Product Description

The LOVEJOY 68514436175 is a flexible coupling hub designed for power transmission applications in industrial and mechanical drive systems. Cast from iron, this hub accepts a maximum bore diameter of 1-5/8 inches and features a 3/8 inches wide by 3/16 inches deep keyway for secure shaft engagement. The overall outside diameter measures 7-1/2 inches with an overall length of 5.69 inches. Rated to 3600 RPM, it is sized for coupling size code 10S. Millwrights, industrial mechanics, and mechanical contractors install this type of hub as part of a complete flexible coupling assembly to connect rotating shafts while accommodating minor misalignment and reducing vibration transmission.

This flexible coupling hub is suited for use in commercial and industrial mechanical drive systems including pumps, compressors, blowers, and conveyor drives. It is intended for use as one half of a two-hub flexible coupling assembly, paired with a spider or elastomeric insert element. The size code 10S designation governs the mating hub, insert, and jaw dimensions within the coupling assembly. Applications span HVAC mechanical rooms, water treatment facilities, manufacturing equipment, and other industrial environments where shaft-to-shaft power transmission is required.

Key Features

• Maximum bore diameter of 1-5/8 inches accommodates a range of shaft sizes
• 3/8 inches by 3/16 inches keyway provides positive rotational drive engagement
• 7-1/2 inch outside diameter and 5.69 inch overall length for coupling size code 10S
• Cast iron construction for durability in industrial mechanical drive environments
• 3600 RPM maximum speed rating suitable for direct-drive and belt-assist configurations

Compatibility

Designed as an OEM-style flexible coupling hub for size code 10S coupling assemblies requiring a maximum bore of 1-5/8 inches. Pair with the appropriate mating hub and spider insert element for a complete flexible coupling assembly.

Installation Notes

Installation of flexible coupling hubs is typically performed by licensed millwrights or qualified industrial mechanics. Disconnect and lock out all power to the drive system before beginning installation per NFPA 70E lockout/tagout requirements. Ensure the shaft and bore are clean and free of burrs before pressing the hub onto the shaft and securing with the keyway. Do not exceed the rated 3600 RPM maximum speed, and verify shaft alignment after assembly to prevent premature wear on the spider insert element.
