A pressure-induced torque is emphasized in externally pressurized bearings having deep pockets, due to the pressure buildup by shaft rotation on the downstream vertical side of the recess. A standard simplified analysis is presented for both laminar and turbulent operation, with improved values for parameters kx and kx, which intervene in the pressure differential equation, as well as for the Couette turbulent shear stress; the mentioned values are valid for large Reynolds numbers. Comparison with experimental data for a water-lubricated test bearing exhibits the importance of the pressure-induced effect on the torque acting on the stationary member of the bearing.
