  • Bearing Tolerances and Precision Levels | AST Bearings

    For example, there is a direct correlation with precision class and bearing life. Raceway parallelism, a feature controlled by ABEC, can impact bearing torque. A non-parallel raceway will result in torque spikes. In high speed applications, bearing runout can result in an imbalance in the rotating mass.
