6 Types of Bearings and Their Advantages - Civil Click
15/7/2020· There is a full film of oil between the bearing and race components so they have very low friction. As compared to standard bearings, they have lower wear and longer life. Since there is less friction and mainly viscous loss to the oil so it should run cooler.
