IEEE transactions on industry applications, 2023
For electrical motors, three translational (x–y–z) and two tilting (θx–θy) rotor motions must be restricted. Ball bearings are commonly used to restrict motion; however, they cannot be applied to high-speed motors with large DN (product of bearing ...

Design Considerations for Bearingless Rotary Pumps
Artificial Organs, 1997Abstract: The designs of rotary blood pumps have shown substantial technical progress over recent years, especially contact bearing designs. However, the concern for potential thromboembolism remains and can only be eliminated by the use of bearingless pumps.
