    2018-1-1 · The cylindrical roller bearing is designed to be subjected to radial load only. In practice, due to the processing and assembly errors, the roller bearing usually will bear some additional bending moment. The transverse forces of the rotor (such as the rotor’s self weight) also generate bending moment at the bearing location.

  • Cylindrical roller bearings | SKF

    SKF Cylindrical roller bearings are available in a wide range of designs, series, variants and sizes. The main design differences are the number of roller rows and the inner/outer ring flanges as well as cage designs and materials. The bearings can meet the challenges of applications faced with heavy radial loads and high speeds.
