Amarillo Drive Shaft CF60 425L

The Amarillo CF60 425L Drive Shaft is a premium composite power transmission solution designed for cooling tower fan drive systems. It connects the electric motor to the gearbox while maintaining stable torque transfer across extended distances. The “L” (Long) configuration is engineered for longer spans between shaft ends without intermediate support bearings, while the CF60 design class ensures reliable performance under continuous industrial duty.

  • Field-erected industrial cooling towers
  • Large HVAC cooling systems
  • Air-cooled heat exchangers (fin-fan systems)
  • Refinery and petrochemical cooling operations
  • Corrosive industrial and coastal environments

Deliver smooth and reliable power transmission in cooling tower systems where stability and reduced mechanical stress are essential. This coupling is designed to maintain consistent performance across long spans.

 

  • Lightweight composite construction reduces load on motor and gearbox bearings
  • High vibration damping improves stability and extends equipment life
  • Designed for long-span applications without intermediate support bearings
  • Low-maintenance design eliminates frequent lubrication and surface treatment needs
  • Factory-balanced for smooth and stable high-speed operation

Every parameter is derived from verified performance testing in real cooling tower conditions. The design maintains consistent efficiency under long spans, continuous load, and high-speed operation.
