    by Edward Gravelle, in Centrifugal Pumps (Second Edition), 1992. Bearings. Ball bearings have evolved to a high state of perfection and are attractive from the standpoints of low friction loss and modest lube system demands. Roller bearings have higher capacity than ball bearings, but are not well suited for high speeds due to a tendency of the rollers to skew in operation.
