Power Losses of Oil-Bath-Lubricated Ball Bearings—A Focus on Churning Losses

Lubricants
This study investigates the power losses of rolling element bearings (REBs) lubricated using an oil bath. Experimental tests conducted on two different deep-groove ball bearings (DGBBs) provide valuable insights into the behaviour of DGBBs under different oil levels, generating essential data for developing accurate models of power losses.
