Gears for Power Plants and Energy Equipment
Turbine gearboxes, coal mills, hydro gates and wind turbine drives run for years without stopping. We manufacture precision gears and shafts for power generation equipment with full documentation.

Continuous Duty, Long Service Life
In power generation, equipment is expected to run continuously for years between overhauls. Gears in turbine gearboxes, mill drives and auxiliary systems must combine high accuracy with long fatigue life, and every part must be traceable.
Nika Gears manufactures case-hardened and ground gears, pinion shafts and gearbox components for power plant equipment, with EN 10204 3.1 certificates and the inspection reports operators and OEMs require.

Where Do Our Gears Run in Power Plants?
Turbine and Generator Gearboxes
Helical gears and pinion shafts for speed-reducing and speed-increasing gearboxes between turbines and generators.
- Ground helical gears
- Low noise and vibration
Mill and Conveyor Drives
Bevel and planetary stages in vertical coal mill drives, and gears for fuel conveyors and ash handling.
- High torque stages
- Wear-resistant flanks
Hydro Gates and Wind Drives
Worm and spur gears for gate and valve actuators, and planetary components for pitch and yaw drives.
- Self-locking worm drives
- Planetary sets

Power Generation Gear Questions
Can you supply ground gears for turbine gearboxes?
Yes. Case-hardened gears are profile ground up to Ø1,250 mm and module 25, with gear measurement reports.
Do you supply complete documentation?
Yes: EN 10204 3.1 certificates, heat-treatment, hardness, gear measurement and dimensional reports.
Can you make planetary components for wind turbines?
We manufacture sun, planet and ring gears to drawing for pitch, yaw and auxiliary drives. Main gearbox components are quoted case by case.
Gears for Reliable Power Generation
Power plants measure success in availability. A gearbox failure in a turbine train, a coal mill or a cooling water pump can force a unit offline, so operators specify gears with tight accuracy, proven materials and complete documentation.
High-speed gearboxes
Gas and steam turbines often run faster than the generator they drive, or drive compressors and pumps at different speeds, so speed-changing gearboxes sit between them. These use helical gears and pinion shafts that are case hardened and ground for low noise and vibration at high pitch-line velocity.
Mill drives
Vertical coal and biomass mills use bevel-planetary gearboxes that carry very high torque. Their bevel stages and planetary sets must be manufactured and matched carefully, with ring gears often nitrided to limit distortion.
Hydro, wind and auxiliaries
Hydropower intake gates and valves are driven by self-locking worm gear actuators. Wind turbines use planetary pitch and yaw drives. Throughout the plant, conveyors, pumps and fans run on standard industrial gearboxes whose spare gears we can produce to drawing.
