  • Rolling element bearing failure analysis A case study

    The service life of bearings is expressed either as a period of time or as the total number of rotations before the occurrence of failures in the inner ring outer ring or in rolling element (ball or roller) because of rolling fatigue due to repeated stress. Rated life of bearing expressed as the period at which equipment or machine element fails under specified condition of use given by its Rolling element bearing failure analysis A case study Ball bearings can be divided into three categories i.e. radial contact angular contact and thrust. The service life of bearing differs from rated life where bearing failure may cause by poor lubrication misalignment and mounting damage before its actual life.
