"WebMar 13, 2024 · Stick-slip, or stiction, is often more problematic in plain bearings than in recirculating bearings. This is because plain bearings experience a greater difference between static and dynamic friction coefficients. And the friction coefficient of a plain bearing can vary, depending on the applied load, wear, and environmental factors. " - Stick-slip motion

Webin the slip mode. In an oscillatory motion both phenomena take place successively, resulting in a stick-slip mode. Since the friction characteristic consists of two qualitatively different parts with a non-smooth transition, the resulting motion also shows a non-smooth behaviour. Thus, stick-slip systems belong to the class of non-
