Lovejoy 68514441468 Flexible Coupling Hub 25mm Bore

Product Description

The LOVEJOY 68514441468 is a flexible coupling hub designed for use in mechanical power transmission applications. This hub features a 25mm maximum bore and an 8mm x 3.3mm keyway (width x depth), allowing it to accept a keyed shaft for positive torque transfer. The outer diameter measures 2.11 inches and the overall length is 2.5 inches. Constructed from sintered iron, the hub provides solid wear resistance in industrial drive applications. Note that a complete flexible coupling assembly requires two hubs and one spider insert, which must be ordered separately. This component is intended for installation by maintenance technicians and mechanical contractors familiar with shaft coupling systems.

This flexible coupling hub is suited for connecting rotating shafts in industrial machinery, pump drives, compressor drives, and similar mechanical power transmission setups. It is typically installed where moderate misalignment accommodation is needed between a driver and driven shaft. The L095 coupling size code identifies the compatible spider and mating hub series for this application. Maximum rated speed is 9,000 RPM, making it appropriate for a range of motor and drive configurations in light to medium industrial service.

Key Features

• 25mm maximum bore accommodates standard metric shaft sizes
• 8mm x 3.3mm keyway (width x depth) for positive keyed-shaft engagement
• 2.11-inch OD and 2.5-inch overall length in a compact sintered iron body
• Rated to 9,000 RPM for compatibility with a wide range of motor-driven equipment
• Coupling size code L095 — order two hubs plus one spider for a complete assembly
• Sintered iron construction offers good wear resistance and dimensional stability

Compatibility

This hub corresponds to coupling size code L095. A complete coupling assembly requires two 68514441468 hubs and one matching L095 spider insert. Verify bore size, keyway dimensions, and coupling size code against the mating component before ordering.

Installation Notes

Installation should be performed by a qualified maintenance technician or millwright. De-energize and lock out all power sources before working on any rotating shaft assembly, following OSHA lockout/tagout procedures. Ensure shaft and bore are clean and free of burrs before pressing or sliding the hub into position. Do not force hubs into alignment — check for angular and parallel shaft misalignment within the coupling manufacturer's allowable tolerances before finalizing the assembly.
