The present paper presents experimental studies conducted on hybrid bearing which includes magnetic repulsion and hydrodynamic actions together into a single sleeve configuration. Such bearing configuration provides non-contact support with minimum possible friction. An experimental setup, designed and developed to investigate the performance characteristics of the different configurations of hybrid bearing, has been described. To examine the performance of hybrid bearing, it was operated at low rotational speed and the performance of different configurations were evaluated by measuring the shaft displacement in X and Y directions using two displacement sensors. The comparison in form of orbit plots has been presented.
