Schaeffler''s asymmetric spherical roller bearing for wind turbines - Bearing …

2/3/2017· Spherical roller bearings which have been optimized to the last µ and a new asymmetric spherical roller bearing allow wind turbines to generate energy even more reliably. All the forces from the wind act directly on the rotor bearing support in a wind turbine and the rolling bearings are therefore subjected to highly dynamic loads and operating conditions.

Optimise bearing conditions and improve output of your turbine

The predominant bearing type in wind turbines are SRB (spherical roller bearings), both in the gear and the main bearing. The main bearing is either grease or oil lubried. In the oil lubried main bearings, it has until now not been common practice to filter the oil, but doing so makes good sense.

What bearings are used in wind turbines? - Insight - Acorn …

23/3/2020· Roller bearings are commonly found in the main shaft of a wind turbine. Spherical roller bearings are often used in this area thanks to their ability to handle angular misalignment. Cylindrical roller bearings are also frequently used in conjunction with tapered roller bearings to provide superior coination load capacity.
