Amarillo Drive Shaft CF67 275L

The Amarillo Drive Shaft CF67 275L is a precision-engineered composite power transmission shaft designed for demanding cooling tower applications. It connects the electric motor to the right-angle gear drive, ensuring stable torque transfer for reliable fan operation. Built for long-span configurations, this model delivers high efficiency, reduced vibration, and superior corrosion resistance in harsh industrial environments.

  • Wet cooling tower drive systems
  • Industrial HVAC cooling towers
  • Air-cooled heat exchangers
  • Large field-erected cooling towers
  • OEM replacement and retrofit installations

This drive shaft ensures consistent torque transfer while maintaining smooth fan operation under continuous load. It also improves drivetrain durability by reducing stress on the motor, gearbox, and connected components.

  • 6-bolt orange-coded patented composite flex disc eliminates fretting corrosion
  • Composite center section provides superior vibration and shock damping
  • Lightweight construction significantly reduces motor and gearbox load
  • Dynamically balanced to AGMA 9000-C90 Class 9 standards
  • Supports high misalignment tolerance up to 1.5° per shaft end
  • Designed for long-span cooling tower drive applications

Each specification defines tested performance limits for real industrial cooling tower conditions. It ensures reliable operation even under variable loads and long operating cycles.
