• A Study on the Effects of Ball Defects on the Fatigue Life ...

    In this paper, we present our approach to study the effects of ball defects on fatigue life. Our strategy included characterization of defects encountered in use, generation of similar defects in a laboratory setting, execution of fullscale bearing tests to obtain lifetimes, posttest characterization, and related

  • Baltec Ball Diameter Calibration

    The second approach to ball diameter calibration is the socalled absolute method. In absolute measurement, temperature is a first order error, that must be held at 68 °F (20 °C) exactly, or any variations must be compensated for. A micrometer or threaddriven measuring machine is an example of the absolute concept. The accuracy of such a ...
