Wheel hub bearings operate in harsh conditions, such as high loads, temperature fluctuations, vibration and potential contamination. The precision of surface profile directly affects the distribution of contact stress and friction wear, which in turn impacts bearing life and vehicle safety. In addition, wheel hub bearings typically require effective sealing to prevent the ingress of contaminants, and the precision of surface profile can affect the sealing performance.
