Abstract
A ball bearing assembly for an aircraft includes an inner race, a plurality of balls and an outer race positioned radially outwardly of the plurality of balls. The outer race is secured to a squirrel cage that will connect the outer race to static structure. The squirrel cage has a central axis that will be parallel to an axis of rotation of a rotating member to be supported by the balls. The squirrel cage has a plurality of recesses separated by beams. The beams have a radially inner surface and a radially outer surface defined relative to the rotational axis, and extend between axial ends and through an intermediate portion. The beams have a first radial thickness at the axial ends that is greater than a second radial thickness at the intermediate portion. A rotating assembly is also disclosed.
