Lovejoy 69790406113 Flexible Hub Coupling Alloy Steel

Product Description

The LOVEJOY 69790406113 is a flexible hub coupling designed to transmit torque between shafts while accommodating minor misalignment in mechanical drive systems. Built from alloy steel, this hub accepts a maximum bore diameter of 1-1/8 inches and measures 2-1/2 inches in outer diameter. With a maximum operating speed of 6000 RPM, it is suited for demanding power transmission applications. The coupling size code is 1060. Weighing 5.15 pounds, this is a solid, industrial-grade component installed by millwrights, mechanical contractors, and maintenance technicians in pump, motor, and conveyor drive assemblies.

This flexible hub coupling is used in industrial and commercial mechanical drive systems where shaft coupling with vibration dampening and minor misalignment tolerance is required. Typical installations include electric motor-to-pump drives, compressor drives, and general-purpose power transmission setups. The flexible element design helps reduce shock loads transmitted between connected shafts, extending the service life of bearings and connected equipment. It is appropriate for both new installations and replacement service on existing drive systems.

Key Features

• Maximum bore diameter of 1-1/8 inches accommodates common shaft sizes in motor and pump applications
• 2-1/2 inch outer diameter for compact fitment in space-constrained drive assemblies
• Alloy steel construction provides high strength and durability under load
• Rated to 6000 RPM for use in higher-speed drive applications
• Coupling size code 1060 for straightforward cross-reference and replacement ordering
• Flexible hub design accommodates minor shaft misalignment and reduces transmitted vibration

Compatibility

Designed as an OEM-style replacement or new-installation hub coupling for size 1060 series flexible coupling assemblies in industrial power transmission systems.

Installation Notes

Installation is performed by qualified millwrights or mechanical technicians. De-energize and lock out the drive motor completely before removing or installing any coupling component. Ensure shaft and bore are clean and free of burrs before pressing or keying the hub onto the shaft. Verify shaft alignment to manufacturer tolerances after installation to prevent premature wear on the flexible element and connected bearings.
