# Wind Turbine Gearbox Bearing Requirements & Solutions

## Gearbox

Wind turbine gearboxes increase rotational speed from the main shaft (10-20 rpm) to the generator’s rotational speed (1000-1500 rpm). They operate under significant loads and require highly reliable bearings.

## Operating Conditions

- High torque
- Combined radial and axial loads
- Long-term continuous operation
- Vibrations from uneven wind

## Solutions

Cylindrical roller bearings and tapered roller bearings with high load-carrying capacity are used. Precision bearings are applied to ensure smooth operation. Oil lubrication with a filtration system is recommended.
