When determining the bearing size, the pv diagrams at right may be used to give an indication of whether a given bearing can be used under the actual operating conditions (load, sliding velocity).
If the check reveals that operating data is within area I, then the service life Gh can be determined by using the equation shown 'Calculation procedure for the nominal service life'. But if the area II is obtained, then we recommend contacting one of our experts, or to verify the suitability of the bearing by an advance test. If necessary, the bearing size should be modified in such a way that the value for the product p x v reaches area I where p = specific bearing load (MPa) and v = sliding velocity (m/s).
