The Effect of Extreme Pressure (EP) Lubricants on the Life of Rolling Element Bearings

Bearing tests showed that lubricants containing sulphur and phosphorus extreme pressure (EP) additives reduce the life of rolling bearings compared with similar lubricants without EP additives. High-resolution electron microscopy revealed a remarkable difference of contact surface topography and mic...

Description
Summary:Bearing tests showed that lubricants containing sulphur and phosphorus extreme pressure (EP) additives reduce the life of rolling bearings compared with similar lubricants without EP additives. High-resolution electron microscopy revealed a remarkable difference of contact surface topography and microstructural changes between bearings tested with or without EP additives.
