  • Bearing Life Calculation - Bearing Loads & Speeds ...

    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. It would be too difficult to show all the methods of calculating P for all the bearing types shown. For tapered roller bearings, the “K” thrust factor is employed.
