Abstract
An annular cage for the rollers of a bearing is located in the annular space between two bearing races and is normally spaced from both races when concentric. The cage is so constructed that, when unbalanced forces on the cage during rotation in the bearing tend to move the cage from its concentric position into contact with a piloting surface, hydrodynamic forces are developed which act to keep the cage out of contact with that surface.
