Investigation of Drag and Churning Losses on Tapered Roller Bearings
Strojniški vestnik – Journal of Mechanical Engineering, 2015 Today there are a lot of findings to determine losses caused by contact forces inside roller bearings. But there are also losses in bearings caused by displacement of lubricant. These are known as churning or drag losses. In general the bearing manufacturers give recommendations how to reduce them.
