Turbine Gearing

Wind Energy

Precision gearing and gearbox components for wind turbine drivetrains and yaw-and-pitch systems.

Built for wind energy

Wind energy demands gearing that runs quietly and reliably through millions of load cycles atop the tower. We manufacture and repair precision helical gearing, planetary components, and drive parts for wind turbine gearboxes — held to tight quality standards for smooth, low-vibration operation and long service life.

Challenges we solve

  • Millions of load cycles with minimal maintenance access
  • Low-vibration, high-precision helical gearing
  • Planetary and drive components for turbine gearboxes
  • Repair and reverse engineering of legacy units
