Lovejoy 69790405233 Flexible Coupling Hub Series 1040

Product Description

The LOVEJOY 69790405233 is an alloy steel flexible coupling hub designed for use in grid-style shaft coupling assemblies. This hub accommodates bore diameters from 0.5 inches up to 1-5/8 inches and features a 2.0-inch outside diameter, making it compatible with the Series 1040 coupling platform. The hub is rated at 2,200 inch-pounds of torque, providing substantial load-handling capacity for industrial drive applications. It is sold individually; a complete grid coupling assembly requires two hubs, one grid, and one cover ordered separately. Technicians and millwrights install these hubs in mechanical power transmission systems where controlled torsional flexibility and shock absorption are required.

This hub is suited for industrial and light commercial power transmission installations, including pump drives, conveyor systems, compressor drives, and similar rotating equipment where shaft misalignment compensation is needed. The Series 1040 designation identifies a standardized coupling family, allowing hubs to be paired with matching grids and covers within that series. Installation is typically performed by millwrights or maintenance technicians familiar with shaft coupling assembly procedures.

Key Features

• Alloy steel construction for high strength and durability in demanding drive applications
• Bore range of 0.5 inches to 1-5/8 inches accommodates a variety of shaft sizes
• 2.0-inch outside diameter hub fits Series 1040 grid coupling components
• Rated torque of 2,200 inch-pounds for reliable power transmission capacity
• Sold as a single hub; order two hubs, one grid, and one cover for a complete coupling assembly
• Series 1040 standardization allows straightforward component matching and field replacement

Compatibility

Designed for use within the LOVEJOY Series 1040 grid coupling platform. A complete assembly requires two Series 1040 hubs, one matching grid, and one Series 1040 cover. Confirm series designation and bore requirements before ordering.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician. Disconnect and lock out all power to the drive system before beginning coupling work, following OSHA lockout/tagout procedures. Hubs should be properly keyed and secured to their respective shafts before the grid and cover are assembled. Do not exceed the rated bore range; verify shaft dimensions and coupling series compatibility prior to installation.
