Lovejoy 68514436157 Flexible Coupling Hub 1.5 in Bore

Product Description

The LOVEJOY 68514436157 is a flexible coupling hub designed for power transmission applications in industrial and mechanical systems. It accepts a maximum bore diameter of 1.5 inches and features a keyway measuring 0.375 inches wide by 0.1875 inches deep for positive shaft engagement. Constructed from cast iron, this hub offers solid rigidity and resistance to wear under rotational load. With a 6.35-inch outer diameter and an overall length of 5.06 inches, it is sized for medium-duty drive train configurations. The 68514436157 is rated to a maximum of 3,750 RPM. Mechanical contractors and industrial maintenance technicians are the typical installers.

This flexible coupling hub is suited for use in pump drives, compressor assemblies, conveyor systems, and general industrial power transmission setups where shaft misalignment compensation and vibration dampening are required. The cast iron construction makes it appropriate for environments where moderate mechanical stress and rotational loads are present. It is sold individually and carries a package quantity of one unit per order.

Key Features

• Maximum bore diameter of 1.5 inches accommodates a wide range of shaft sizes
• Keyway dimensions of 0.375 inches wide by 0.1875 inches deep for secure shaft keying
• Cast iron construction provides durability and resistance to rotational stress
• Rated to 3,750 RPM maximum for reliable high-speed drive applications
• 6.35-inch outer diameter and 5.06-inch overall length suit medium-duty installations
• Coupling size code 9S for reference when cross-matching compatible spider or insert elements

Compatibility

Designed as an OEM-style replacement or service hub for flexible jaw-type coupling assemblies of equivalent bore and keyway specifications. Verify coupling size code 9S compatibility with the mating hub and spider element before installation.

Installation Notes

Installation should be performed by a qualified mechanical technician familiar with power transmission components and applicable ANSI safety standards. Disconnect and lock out all power to the drive system before removing the existing coupling hub. Do not press or hammer the hub onto the shaft in a way that may damage the keyway or bore surface; use a proper hub installation tool where required. Ensure the mating hub, spider insert, and shaft are all clean and free of burrs before assembly.
