Performance of bearings in the machinery governs its life. Among all type of bearings, hydrodynamic bearings are the economic to implement. However these bearings show undesired performance during low rotational operating speed and during starting and stopping of the machinery (due to insufficient development of hydrodynamic film). To overcome this problem, the hydrodynamic bearing is hybridized with magnetic bearing. To develop the hybrid bearing three methods have been attempted. The advantage and short coming of each method has been reported
