The bearing cage with high speed features has a pocket with a first flange and a second flange which defines the outer boundaries of the pocket. The first flange and the second flange each have a plurality of inwardly directed protrusions facing each other. The protrusions are contactable at each end of rollers, which are arranged in the bearing cage. The protrusions can be dome shaped, creating a small area of contact between the rollers and protrusions. The point of contact between the rollers and the protrusions is at the center of the rollers, which reduces the relative speed between the ends of the pockets and the rollers.
