The life of rotating machines are mainly depended on the working condition of the bearings. Bearing failures leads to putting the machine in breakdown maintenance which leads to create burden on production. If bearing failure could be estimated then these breakdown could be avoided by implication of proper maintenance strategies. .In this literature survey study has been carried out on defect propagation of bearing and misalignment of shaft using vibration signature.. Different techniques were used by aothors to study crack propagation and misalignment is mentioned in this literature.
