  • Effects of Heat Treatments on Steels for Bearing

    The thermal contact resistance between the balls and the inner and outer rings of a space-use ball bearing is investigated assuming that heat transfer between smooth contacting elements occurs through the elastic contact areas. It is also assumed that the stationary bearing sustains axial, radial or combined loads under a steady-state temperature condition. The shapes and sizes of the contact ...
