Abstract: Rotating and Reciprocating parts are the basic parts of any manufacturing industry. The mechanical problems caused by the electric motors is generally because of vibrations produced by rotating machinery. The efficiency of the motor decreases because of the misalignments and this further leads to failure of bearings and couplings. As, exact alignment is not possible but can be adjusted in acceptable range which can avoid any damage or failure in machines and results in long life of machines. There are various reasons behind misalignment which causes machines instability are thermal distortion of machines, disproportionateness in functional loads, improper assembly of machines, unequal settlement of foundation, etc. The incorrect arrangement of coupling or condition of being out of correct position or something is improperly adjusted is known a misalignment. Hybrid bearings also shows lower coefficient of thermal expansion with high bearing stiffness and greater hardness. This paper describes the type of bearing can be used to replace the old traditional steel bearings which provides comparably better performance. As described above it can be stated that the ceramic bearings perform better in terms of service life. It also increases the lubricant life, reduced wear from vibration and can be operated at lower temperatures.
