Wear and Surface Fatigue in Rolling Bearings - BEARING NEWS
14/5/2020· Wear in rolling bearings is a non-linear phenomenon, and even observations and measurement of rolling bearing wear in regular intervals show that simple intuition is not sufficient to predict how wear will evolve in time. This is due to a variety of reasons; wear depends mainly on local sliding and local load, and wear itself modifies these two
