Patent ID: 8382379

Claim:
A ball roller bearing, comprising: an outer bearing race; an inner bearing race, and a multiplicity of ball rollers, which are disposed between the outer bearing race and the inner bearing race, which have two side faces that are flattened symmetrically as a departure from a basic ball shape and are disposed parallel to one another, and which are held at uniform distances from one another in a circumferential direction by a bearing cage, the ball rollers have a width between the two side faces of approximately 70% of a diameter of a basic ball shape, the ball rollers rolling on a bearing surface of two groove-shaped raceways, each groove-shaped raceway is machined into an inside of the outer hearing race and into an outside of the inner bearing race and a depth of which is dimensioned in such a way that a distance between the inside of the outer bearing race and the outside of the inner bearing race is less than the width of the bah rollers, wherein the bearing cage of the ball roller bearing is a window cage, individual cage pockets of which each have an integrated overall contour of a cross-sectional contour of a ball roller disposed in longitudinal and transverse directions relative to the circumferential direction and are disposed spaced apart in such a way that a sum of the flanking distances on either side of each ball roller in a circumferential direction at a pitch circle is less than the diameter of the basic ball shape of one individual ball roller.
