Lovejoy 68514436177 Flexible Coupling Hub 1-3/4 in Bore

Product Description

The LOVEJOY 68514436177 is a cast iron flexible coupling hub designed for power transmission applications in industrial and mechanical drive systems. With a maximum bore diameter of 1-3/4 inches and a 3/8 inches by 3/16 inches keyway width by depth, this hub accepts a keyed shaft for positive torque transfer. The overall outside diameter measures 7-1/2 inches and the overall length is 5.69 inches. Rated to 3600 RPM, it suits moderate- to high-speed drive train configurations. Mechanical contractors, millwrights, and industrial maintenance technicians are the typical installers for this type of component.

This flexible coupling hub is used in industrial drive systems where shaft misalignment absorption and vibration dampening are required between a driver and driven component. Typical applications include pumps, compressors, fans, and conveyor drives in both commercial and light industrial settings. The coupling size code is 10S. At 11.69 pounds, this is a heavy-duty hub suited for equipment requiring a robust, durable iron construction at the coupling joint.

Key Features

• Maximum bore diameter of 1-3/4 inches accommodates a range of drive shaft sizes
• Keyway dimensions of 3/8 inches wide by 3/16 inches deep for keyed shaft engagement
• 7-1/2 inch outside diameter and 5.69 inch overall length for defined envelope fitment
• Cast iron construction provides durability and resistance to wear in power transmission service
• Rated to 3600 RPM for moderate- to high-speed mechanical drive applications
• Coupling size code 10S for cross-reference and replacement identification

Compatibility

Designed as an OEM-style replacement or direct-fit flexible coupling hub for industrial drive systems requiring a size 10S coupling hub with a 1-3/4 inch maximum bore and cast iron construction.

Installation Notes

Installation of flexible coupling hubs should be performed by a qualified millwright or mechanical technician. De-energize and lock out the drive system completely before removing the existing coupling or installing the new hub. Ensure the shaft is clean and free of burrs before pressing the hub into position, and verify keyway alignment before final seating. Consult applicable machinery manufacturer documentation for bore fit tolerances and coupling alignment procedures.
