Modeling and Simulation of Cage Wear in Solid-Lubricated Rolling Bearings

Cage not only separates the rolling elements but play an essential role of lubricant supplier in solid lubricated rolling bearings, thereby lubricating the rolling contacts. In such bearings, whose service life can be significantly extended by targeted cage wear, a better understanding and a reliabl...
