the axial thrust bearing. Greater design capacity would provide the same margin with respect to radial loads.

The margins evident in Table 3 for the multistage pump may appear excessive, but until more operating knowledge about such pumps is acquired, it would appear that this degree of conservatism in designing magnetic bearings for pumps is merited.
