The effect of lubricant temperature on dynamic

2020-7-13 3 Effect of different lubricants on the dynamic behavior of bearing When the bearing is lubricated by different lubricants the traction force between ball and raceway differs from each other greatly which results in different behavior of dynamic characteristic Therefore the effect of different lubricants should be considered
