In extreme operating condition of a fluid film bearing (FFB), metal to metal contact occurs and resulting in failure of the bearings. Under such extreme conditions wear of the FFB are highly sensitive to the tolerance of the bearings. A theoretical study on the tolerance sensitivity of a sugar mill bearing has been performed. To provide solution to reduce the sensitivity of the FFB, a hybrid (FFB + rotating magnetization direction Magnetic Bearing (RMDMB)) is proposed. The tolerance sensitivity towards load carrying capacity of FFB, RMDMB and Hybrid bearing is evaluated for the sugar mill bearing and results are presented.
