This small blade bearing is used for pitching regulation of blades on the wind turbine. Since yaw bearing and pitch bearing are exposed to weathering, so the working temperature and painting requirements need special attention.

Working temperature of small pitch bearing

The common working temperature of slewing bearing is -20℃ to 80℃, if it's over this range, then user should contact supplier. The material of sealings and the lubrication grease may be different according to the temperature.

Painting requirements

If the slewing bearing of wind turbine will be used in wet or rainny place, then it's suggested that user choose the slewing ring with painting, which can protect bearings from rust or corrosion, and extend bearings service life.
