Lovejoy 69790405462 Flexible Hub Coupling 1 in Bore

Product Description

The LOVEJOY 69790405462 is a flexible hub coupling designed to connect rotating shafts in mechanical drive systems. It accommodates a maximum bore diameter of 1 inch and features an outer diameter of 1.88 inches, making it suited for compact drive train installations. Constructed from alloy steel, this hub coupling delivers the strength and wear resistance required in industrial and commercial power transmission applications. It is rated for speeds up to 6000 RPM, supporting a wide range of motor and drive configurations. Mechanical contractors, millwrights, and industrial maintenance technicians install this type of coupling during equipment assembly and service.

This flexible hub coupling is used in mechanical power transmission setups where shaft misalignment absorption and torque transfer are required. Typical applications include pumps, compressors, fans, and conveyor drives in both commercial and light industrial environments. The coupling size code is 1020, which is a standard industry sizing reference used to match hubs with compatible spiders and mating hubs. It is sold as a single hub unit, so a complete coupling assembly requires a mating hub and a center spider element.

Key Features

• Maximum bore diameter of 1 inch for compatibility with standard shaft sizes
• Outer diameter of 1.88 inches for compact installation envelopes
• Alloy steel construction for high strength and durability under load
• Rated to 6000 RPM for broad motor and drive application coverage
• Coupling size code 1020 for straightforward cross-referencing with mating components
• Single hub unit sold individually; compatible spider and mating hub sold separately

Compatibility

Designed as an OEM-style replacement or new-installation flexible hub coupling for size 1020 coupling assemblies in mechanical power transmission systems. No specific model or system compatibility was provided in the product data.

Installation Notes

Installation of flexible hub couplings is typically performed by licensed millwrights or mechanical maintenance technicians. De-energize and lock out the drive motor before beginning any shaft coupling work, following OSHA lockout/tagout procedures. Ensure the bore and keyway are clean and free of burrs before pressing or fitting the hub onto the shaft. Do not overtighten set screws beyond hand-verified engagement without reference to the equipment manufacturer's fastener specifications.
