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.
