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.
