ABSTRACT:
A sliding bearing (10) having an inner surface (13a) provided with at least one circumferential recess (15, 16) extending over a portion of the axial dimensions of the inner surface (13).
The recess (15, 16) is located over one portion of the inner surface (13a) which is subjected to a peak oil film pressure (POFP) higher than a minimum value previously calculated for, and/or located up to 45 degrees upstream considering the rotation direction of the shaft, in one region of the inner surface (13a) where the minimum oil film thickness (MOFT) is less than a value previously calculated. Each circumferential recess (15, 16) is defined by a maximum radial depth E, a circumferential range given by the angle .alpha., which vary according to construction and operational features of the bearing (10), in order to cause the values of pressure and/or oil film thickness to meet values previously calculated for the bearing (10).
