  • Bearings for wind turbines

    Spherical roller bearings designed for wind turbine main shafts. The main shaft of a wind turbine must withstand some of the highest forces of any mechanical device. With turbines getting ever larger, this is only likely to increase. Few industrial machines are subject to the variable direction and thrust loads as seen in wind turbine main shafts.

  • What different kinds of bearings are used in wind turbines?

    Cross roller designs are pretty common in these sorts of applications,” says Chartre. The elements in cross roller bearings look like barrels. They’re tipped on their side 45 degrees, with the next one tipped the other way at 45 degrees. The roller touches the raceway along a length rather than on a point like balls do.
