✦ Synopsis

The causes of premature failure of rolling element bearings may be summarised as: From a tribological point of view, the factors that enhance rolling element bearing life in centrifugal pumps are well known: Correct type of oil. Correct viscosity oil. Adequate supply of oil. Cleanliness of oil. Absence of moisture -0) in the oil. Correct oil level in oil sump systems. Correct supply rate in oil mist systems. Correct feed rate in force feed systems.
