    False Brinelling:

    Indentation of raceways may be seen or felt in a dismantled bearing. Caused by vibration transmitted through the bearing when the machine is stationary (in transit for example).

  • 2

    :Spalling

    the separation/flaking of the surface layer of the raceway caused by thermal or mechanical stresses.

  • 3

    The disadvantage of grease:

    it does not conduct heat away from a bearing as efficiently as oil.

  • 4

    What are the most faults to bearing:

    Brinelling, creep, corrosion,chipping,worn case and spalling.

  • 5

    Clean using.

    Trichloroethane or white spirit only

  • 6

    Bearing to be cleaned for further examination should be wiped free of all grease on outer surfaces with the aid of

    dry compressed air for cages and rolling parts then soaked in white spirit.

  • 7

    Loose fit happen when the raceway becomes loose then will rotate on these surface and cause

    corrosion.
