Radial magnetic bearings: An overview
Results in Physics, 2017 Radial magnetic bearings (RMBs) are one of the most commonly used magnetic bearings. They are used widely in the field of ultra-high speed and ultra-precise numerical control machine tools, bearingless motors, high speed flywheels, artificial heart pumps, and molecular pumps, and they are being strengthened and extended in various important areas.

Performance analysis of Pareto optimal bearings subject to surface error variations [PDF]
, 2010 A Pareto optimization study was carried out on a flat pad aerostatic bearing design. Some of the Pareto optimal configurations were then subjected to surface profiling errors including tilt, concavity, convexity and waviness and key performance ...

On the dissipation layer of radial bearings [PDF]
International Journal of Mathematics and Mathematical Sciences, 1988 The dissipation boundary layer of certain radial bearings is identified. It is shown that, under certain conditions, the temperature outside this layer is constant.

The Vibrations of Radial Ball Bearings [PDF]
Proceedings of the Institution of Mechanical Engineers, Part C: Mechanical Engineering Science, 1985 This paper presents a theoretical analysis of the vibration response of a rotating rigid shaft supported by two radial deep-groove lubricated ball bearings. The bearings and their oil films are approximated to a set of non-linear elastic springs and dampers rotating relative to the shaft when it is subjected to a rotating unbalance or inner race ...

Influence of a combined bearing on the buildup rate of a wellbore trajectory control tool
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2020 Conventional methods cannot accurately predict buildup rate. In this study, an algorithm was developed to predict the geometric deflection rate of the tool considering the influence of the radial displacement of a combined bearing.
