Lovejoy 69790405235 Flexible Coupling Hub Alloy Steel

Product Description

The LOVEJOY 69790405235 is a flexible coupling hub machined from alloy steel, designed for use in grid-style flexible couplings. With an outside diameter of 2.5 inches and a coupling size code of 1060, this hub transmits torque between shafts while accommodating slight misalignment and dampening vibration. It is sold as a single hub. To assemble a complete grid coupling, two hubs, one grid element, and one cover are required. Maintenance technicians and industrial mechanics install these components in rotating drive applications across a wide range of industrial machinery.

This hub is suited for industrial power transmission systems where a grid-style flexible coupling is specified. Typical applications include pumps, compressors, conveyors, fans, and other shaft-driven equipment requiring a robust, torque-transmitting connection. The alloy steel construction handles demanding load cycles and provides durability in both indoor and moderate-duty outdoor installations. When ordering for a complete coupling assembly, confirm that the mating hub, grid, and cover share the same 1060 size code.

Key Features

• Coupling size code 1060 for straightforward component matching within the grid coupling series
• Alloy steel construction provides strength and durability under cyclic torque loads
• 2.5 inch outside diameter hub
• Accommodates slight shaft misalignment and reduces vibration transmission when used with a grid element
• Sold individually — two hubs required per complete coupling assembly
• Compatible with standard grid and cover components of the same size code

Compatibility

Designed for use in grid-style flexible coupling assemblies rated to size code 1060. A complete coupling requires two hubs, one grid, and one cover of matching size code. Verify bore requirements and keyway dimensions before ordering to confirm fitment with your specific shaft configuration.

Installation Notes

Installation should be performed by a qualified industrial mechanic or maintenance technician. De-energize and lock out the drive equipment before beginning any coupling work, following OSHA lockout/tagout procedures. Do not hammer hubs directly onto shafts — use a press or appropriate installation tool to avoid damage to the hub bore or shaft. Inspect grid and cover components for wear or damage each time the coupling is disassembled.
