Brinelling

It is the phenomenon observed in ball and roller bearing which leads to premature failure of bearings

There are two types of bearings

True brinelling

It happens due to faulty assembly of bearing , that is while fitting excessive hammering is carried out which deformates the ball and raw

False brinelling

It is due to vibration caused by machinery itself or by vibration transmitted by other machinery thus brinell may occur during machine standstill or in operation

To avoid brinelling

  • Reduce vibration 
  • Top bearing of purifier is mounted on spring casing
  • Machine not to be kept in standstill for long term at regular intervals
  • After overhauling and trying out purifier it is advisablento remive bowl and keep outside to avoid damage to bearing.
  • Avoid excessive hammering while fitting
