Power Generation

Turbine, generator, and auxiliary drive gearing engineered for smooth, quiet, high-reliability operation.

Built for power generation

Power generation demands gearing that runs smoothly and reliably for years between outages. We manufacture precision helical and double-helical gears and complete drives for turbine, generator, and balance-of-plant equipment, held to tight quality standards and fully documented for critical-service traceability.

Challenges we solve

  • High-speed, low-vibration turbine and generator drives
  • Precision helical gearing for quiet, smooth operation
  • Full documentation and traceability for critical service
  • Long service intervals between planned outages
