Bearing Solutions and Services for Wind Turbine Gearboxes


Increasing megawatt ratings require larger and higher capacity gearboxes. The operating conditions for rolling bearings in wind turbine gearboxes cannot be compared with those for static gearboxes. Highly dynamic forces with extreme peak loads and minimal loads, sudden load reversals and widely differing operating temperatures are some of the challenges facing the bearing arrangements. Bearings with high static load safety factor and secure dynamic design according to international design guidelines such as ISO 81 400 are the right solution here.

INA and FAG bearings used:
Tapered roller bearings, cylindrical roller bearings with cage, full complement cylindrical roller bearings, deep groove ball bearings and four point contact bearings.
