# Pitch and Main-Shaft Bearing Habits for Wind Turbine Campaigns

Wind turbine maintenance windows are weather-limited. Main-shaft and pitch bearings see slow rotation, high load, and grease systems that must keep moisture and wear debris out between campaigns.

False brinelling from standstill vibration and seal leakage are quiet life reducers. Condition monitoring helps only with a healthy baseline. Spare strategy should favor documented interchange before rope-access work starts.
