  • What different kinds of bearings are used in wind

    2017-1-24 · Spherical roller bearings are often used in the main shaft of the turbine. It is also common to find a tapered roller bearings (TRB) used in combination with a cylindrical roller bearing (CRB) at this location, said Stephen Curtis, director of Renewable Energy Business. There are a number of different bearing designs that …

  • Tapered Roller Bearings - an overview |

    Tapered roller bearings also have much higher internal friction and thus will not run as fast and as cool as comparable ball bearings. Therefore, proper lubrication, i.e., proper type of lubricant, proper amount, and proper application method will be even more important with roller and tapered roller bearings than with ball bearings.
