Bearing types

The following bearing types are in particular used in electric motors and electrical appliances:

  • Deep groove ball bearings
  • Single-row angular contact ball bearings
  • Spindle bearings
  • Cylindrical roller bearings with cage
  • Tapered roller bearings
  • Spherical roller bearings
  • Axial spherical roller bearings
  • Plain bearings

The table compares the performance of different bearing types with regard to load, accuracy, speed, noise and friction.
