Lovejoy 68514411087 Flexible Coupling Hub 3/4 in Bore

Product Description

The LOVEJOY 68514411087 is a flexible coupling hub designed for use in mechanical power transmission applications. It accepts a maximum bore diameter of 3/4 inches and features a keyway measuring 3/16 inches wide by 3/32 inches deep for secure shaft engagement. The hub has an outer diameter of 2.11 inches and an overall length of 2.5 inches. Constructed from sintered iron, it is built to handle the rotational loads and minor shaft misalignment common in industrial and commercial equipment. Note that two hubs and one spider element are required to assemble a complete flexible coupling.

This coupling hub is suited for use in HVAC equipment, pumps, compressors, fans, and general industrial machinery where flexible shaft couplings are required. The L095 coupling size code and 9000 RPM maximum speed rating make it appropriate for moderate- to high-speed shaft connections in both light industrial and commercial service environments. It is typically installed by millwrights, HVAC mechanics, or equipment technicians during drivetrain assembly or replacement service.

Key Features

• Maximum bore diameter of 3/4 inches for versatile shaft fitment
• Keyway dimensions of 3/16 inches wide by 3/32 inches deep for positive shaft drive engagement
• 2.11 inch outer diameter and 2.5 inch overall length
• Sintered iron construction for durability under rotational load
• Rated to 9000 RPM maximum for moderate- to high-speed applications
• Coupling size code L095 — order two hubs plus one spider for a complete assembly

Compatibility

Designed as an OEM-style replacement or new-installation hub for L095 series jaw-type flexible couplings. A matching hub and a separate spider element must be purchased to complete the coupling assembly.

Installation Notes

Installation should be performed by a qualified mechanic or technician familiar with mechanical power transmission components. Disconnect and lock out all power to the driven equipment before removing or installing any coupling components. Ensure the shaft and bore are clean and free of burrs before pressing the hub into position, and verify keyway alignment before final seating. Consult applicable equipment manufacturer specifications and relevant safety codes before returning the unit to service.
