Abstract
A roller bearing comprises inner and outer rings defining a toroidal inner raceway rotatable about a bearing axis (A). A plurality of concave rolling elements is arranged in a single row between the outer and inner rings. Each of the plurality of concave rolling elements is a symmetrical cylindrical roller having circular ends, a roller axis passing through the center of the circular ends, and a concave side profile that extends continuously between the circular ends. The toroidal inner and outer raceways each have a convex race surface that continuously engages the concave side profile between the circular ends of each concave rolling element with a first radius and extends axially beyond the circular ends of each concave rolling element with a second radius that is less than the first radius.
