Lovejoy 69790405236 Flexible Coupling Hub 3 in Alloy Steel

Product Description

The LOVEJOY 69790405236 is a flexible coupling hub machined from alloy steel, designed for use in grid-style flexible shaft couplings. With a 3-inch outside diameter and coupling size code 1070, this hub connects rotating shafts in industrial drive systems and transmits torque while accommodating minor misalignment. Sold individually, a complete coupling assembly requires two hubs, one grid, and one cover — each ordered separately. Industrial maintenance technicians and millwrights commonly install these hubs in pump, compressor, conveyor, and general power-transmission applications.

This hub is suited for industrial environments where a grid-style flexible coupling is specified. The size 1070 designation identifies it within the standard LOVEJOY grid coupling series, making selection and replacement straightforward when a coupling size code is already known from the existing installation. It is appropriate for both new installations and direct replacement of worn or damaged hubs in existing assemblies.

Key Features

• Alloy steel construction for high torque capacity and durability in demanding industrial service
• 3-inch outside diameter, coupling size code 1070
• Grid-style flexible coupling design accommodates shaft misalignment and dampens shock loads
• Sold as a single hub — order two hubs, one grid, and one cover for a complete coupling assembly
• Pkg Qty of 1 with a minimum order quantity of 1

Compatibility

Designed as an OEM-style replacement or new-installation hub for grid-style flexible couplings in industrial power-transmission systems where a size 1070 coupling hub is specified.

Installation Notes

Installation is typically performed by millwrights or industrial maintenance technicians. Disconnect and lock out all power to the drive system before removing or installing coupling components. Proper shaft alignment should be verified with dial indicators before final assembly, and the complete coupling — two hubs, one grid, and one cover — must be assembled before returning the drive to service. Follow applicable OSHA lockout/tagout procedures throughout the process.
