This carbon fiber composite drive shaft improves cooling tower reliability while reducing maintenance, vibration, and bearing wear in continuous-duty industrial environments.
- Carbon fiber center tube provides exceptional stiffness and long-span capability
- Lightweight composite construction reduces motor and gearbox bearing loads
- Unitized composite flex elements eliminate fretting corrosion and lubrication needs
- 316 stainless steel hardware delivers strong corrosion resistance in humid environments
- High misalignment tolerance supports up to 1° angular movement per shaft end
- Dynamically balanced to ANSI/AGMA 9000-C90 Class 9 standards
- Infinite fatigue-life composite design improves long-term operational reliability
It is engineered for stable power transmission and reliable cooling tower operation under demanding industrial load conditions.
