The old method of employing personnel to lubricate all parts of the machine has its disadvantages, like it needs to employ specially trained personnel, there is wastage of precious petroleum products (Oil or Grease), machine has to be stopped so that lubrication is done, thereby causing loss of machine time & man-hours and many other problems. Centralised lubrication systems eliminate all problems caused & make it easier to lubricate. We can say that it is a process or method wherein the machines are lubricated with ‘Minimum efforts, Maximum results’.
