The "equivalent bearing load", P, used in the rating life formula, needs to be calculated when combined radial and axial loads occur. This calculation can be somewhat complicated as it depends on the relative magnitudes of the radial and thrust loads to each other and the contact angle developed by the bearing.

Speed cascade control is the most important part of the control system for modern profile mills. Since the distance between the stands is short and the rolling speed is fast, the control system must have high accuracy, good stability, fast speed regulation and selfadaption. Precise material tracking is the base for .
