  • What different kinds of bearings are used in wind

    In more specific terms, wind turbines use spherical roller bearings, slewing ring bearings, cylindrical roller bearings, four-point contact ball bearings, deep groove ball bearings, and tapered roller bearings. In many instances, wind turbine gearbox bearing failures have occurred well before the rated end-of-life of the bearing.

    These bearings operate under low loads and high speeds, and therefore, are prone to skidding, i.e., gross-sliding of rolling-elements on raceways. Sliding can lead to rolling surface distress and eventually to premature failure. Hence, skidding is an important design criterion for wind-turbine bearings. Both ball-bearings and roller-bearings …
