Abstract
A pair of hybrid ball bearings have stainless steel rings and ceramic balls and are configured such that when the first inner ring and the first outer ring are in contact with the first plurality of ceramic balls under zero measuring load and zero mounting load and the second inner ring and the second outer ring are in contact with the second plurality of ceramic balls under zero measuring load and zero mounting load a certain gap exists between either the inner rings or the outer rings. The gap is based on the diameter of the inner ring or on the pitch diameter of the balls and on whether the bearings have an X configuration or an O configuration.
