This hybrid composite drive shaft is built to enhance long-span performance while reducing maintenance and mechanical stress in continuous-duty cooling tower systems.
- Advanced hybrid carbon fiber + fiberglass construction improves stiffness and span capability
- Patented unitized flex elements eliminate fretting corrosion and stress cracking
- Lightweight design reduces motor and gearbox bearing loads significantly
- High misalignment tolerance supports up to 1° per shaft end
- Corrosion-free operation in humid and chemically aggressive cooling tower environments
- High critical speed capability enables longer spans without intermediate bearings
- 316 stainless steel hardware ensures long-term durability and corrosion resistance
It is engineered for high-demand cooling tower power transmission with stable performance under continuous industrial operating conditions.
