  • SKF Tapered Roller Bearing Failure Basic Model

    2021-3-10 · Contact fatigue failure is one of the most common failure modes of all types of tapered roller bearings. It is the failure caused by repeated effects of cyclic contact stress on the bearing surface. Contact fatigue spalling on the surface of SKF bearing parts is a process from fatigue initiation and propagation to cracking.

    All tapered roller bearings need to be set with a slight preload in order to function properly. If the preload is too great, the bearings generate excessive heat and wear out relatively quickly. If the preload is too low, the bearing has excess clearance or endplay and may not be able to carry the loads correctly. Premature failure is likely.
