The bearing performance depends on the groove depth and pattern. Values in this calculator are based on dimensions of slimairbearings ( The dimensions and bearing performance is only a good approximation. Mearsured curves will become available June 2008.

h0: The maximum value of the 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, ranging between 3 and 8 micron for bearing diameters ranging between 25 and 50 mm diameter.
