Pressure distribution bearing configuration I) and II) respectively, but with 5 pockets. In configuration II a circumferential flow takes place, with lubricant flowing from the  pocket with higher pressure to the one with lower pressure. The stiffness of this bearing is somewhat negatively affected but the flow rate through this bearing is significantly smaller.
