# Nacelle Orientation System

## Nacelle Orientation System

The nacelle orientation system rotates the nacelle to align the rotor with the wind direction. It withstands significant loads from the nacelle's weight and wind forces.

## Loads

- Nacelle weight (up to 300 tons)
- Wind loads on the nacelle
- Torque loads during rotation
- Vibration from uneven wind

## Solutions

Large-sized spherical roller bearings and roller supports are used. Bearings with gear rings are applied for the rotation drive. Bearings with automatic lubrication systems and condition monitoring are recommended.
