New ZKL bearing for wind energy

ZKL expands its portfolio of wind power products. Currently, 240/850EW33MH bearings for 2.5 MW wind power plants are in the prototype production phase. These bearings are heading to China, where they will be fitted on the main shaft of wind farms.

Drive-train configuration is different compared to other customers. The main shaft torque is still transmitted to the generator via planetary gearbox, however main bearing is only one and bears both – radial and thrust loads. This type of drive-train configuration is known as a “three-point suspension”.

In parallel with this project, ZKL also develops activities in other territories, negotiates with new customers and applies the latest knowledge from the field in the development of the main wind farm bearings.


ZKL is the biggest manufacturer of large-scale spherical-roller, special and split bearings in Central Europe.
