2R2: A small diameter of the inlet hole 2R2 is favorable with respect to the self-aligning  capability of the bearing but may cause the pressure to drop locally by inertia forces. The pressure drop by inertia forces can calculated with equation (12.4) of the book.

h2: The highest load capacity is obtained with small h0/h2 ratio which means a relative large pocket depth h2. A shallow pocket however is needed to obtain axial bearing stiffness and self aligning capability. In order to select the optimal value for R1/R0 and h0/h2 to achieve a good compromise in self aligning capability, axial stiffness and load capacity consult the design charts available in the book.

h0: The highest axial bearing stiffness, self-aligning capability and the minimal flow is obtained with the smallest film thickness. The required film thickness depends on bearing deflections and flatness of the bearing surface and is usually related to the bearing size.
