  • Operating temperature and speed | SKF

    The operating temperature of a bearing is the steady state temperature it attains when running and in thermal equilibrium with its surrounding elements. The operating temperature results from ( diagram 1 ): the heat generated by the bearing, as a result of the combined bearing and seal frictional power loss.
