Calculating Mill Drive RPMs: Is Your Mill Up to Speed? By Robert A. Sladky Vice President Tube Mill Engineering Many "W" style mills that have the ability to shim up the bottom driven shafts in each section to maintain metal line after tooling is reworked, and are many times also equipped with a individual motor drive in each of the three sections as illustrated below.
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.
