# Low-speed Oscillatory Movements in Wind Turbine Blade and Tower Adjustment

## Low-speed Oscillatory Movements During Blade and Tower Adjustment

Wind turbines feature systems for adjusting blade pitch and tower rotation. These systems operate in low-speed oscillatory motion, creating unique conditions for bearings.

## Load Characteristics

- Low rotational speed (fractions of a revolution)
- Frequent reverse movements
- High loads during position locking
- Vibration from uneven wind

## Solutions

Bearings with high load capacity at low speeds are used. Spherical roller bearings and tapered roller bearings are employed. Bearings with reinforced cages are recommended for operation under reverse load conditions.
