    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 …

    2021-6-4 · ROLLER BEARINGS Rolling-element bearings utilize balls (ball bearings) or cylindrical rollers (roller or “needle” bearings). These elements are contained with bearing rings or “races”, where they facilitate motion with little resistance to sliding. Ball bearings, the most common type, can accommodate both radial and axial loads.
