# Blade Pitch Control System

## Blade Pitch Control System

The blade pitch control system adjusts the blade attack angle to optimize energy production and ensure safety during strong winds. It operates under low-speed oscillating movements.

## Load Characteristics

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

## Solutions

Spherical roller bearings and tapered roller bearings with high load-carrying capacity are applied. Bearings with reinforced cages are used for operation under reversing load conditions. The use of preloaded bearings is recommended.
