Addax Drive Shaft Composite Coupling LRX850.625

The Rexnord Addax Composite Coupling LRX 850.625 is a high-capacity floating composite driveshaft engineered for demanding industrial cooling tower and process applications. Built for long-span power transmission, it delivers high torque handling, reduced drivetrain stress, and superior corrosion resistance while operating without intermediate support bearings.

  • Industrial cooling tower fan drives
  • Vertical pump drive systems
  • Paper and pulp processing plants
  • Industrial compressor systems
  • Chemical processing facilities
  • High-humidity and corrosive industrial environments

This composite coupling is designed for high-load industrial systems where lightweight construction and long-span stability are critical.

  • Continuous-fiber composite spacer dramatically reduces rotating mass compared to steel shafts
  • Urethane-encapsulated flex elements minimize fretting corrosion and drivetrain wear
  • High-stiffness composite construction improves critical speed stability during operation
  • 316 stainless steel hubs and hardware provide strong corrosion resistance in harsh environments
  • The floating shaft configuration eliminates the center steady bearing requirements
  • Low thermal expansion helps maintain alignment consistency during temperature changes
  • Lightweight assembly reduces startup inertia and bearing stress on connected equipment

 

It is engineered for continuous-duty industrial applications requiring long-span operation, stable torque transfer, and high structural reliability.
