Lovejoy 69790405498 Flexible Hub Coupling 3 in Od

Product Description

The LOVEJOY 69790405498 is a flexible hub coupling designed to connect rotating shafts in mechanical drive systems while absorbing vibration and accommodating minor shaft misalignment. Built from alloy steel, this coupling measures 3 inches in outer diameter and accepts a maximum bore diameter of 2-3/8 inches. It carries a coupling size code of 1070 and is rated up to 5500 RPM, making it suitable for demanding industrial and commercial drive applications. Installation is typically handled by mechanical technicians and maintenance professionals working on pumps, compressors, fans, and similar rotating equipment.

This flexible hub coupling is used in industrial and commercial settings where shaft-to-shaft power transmission is required. Typical applications include pump drives, fan assemblies, compressor connections, and other rotating equipment that benefits from a flexible element to reduce shock loads and dampen vibration between drive and driven components. At 6.3 pounds, the alloy steel construction provides durability in continuous-duty service environments.

Key Features

• Alloy steel construction for high-strength, continuous-duty performance
• 3 inch outer diameter with a 2-3/8 inch maximum bore capacity
• Rated to 5500 RPM for high-speed drive applications
• Coupling size code 1070 for straightforward replacement identification
