Patent ID: 8596873

Claim:
A ball roller bearing, comprising: an outer bearing ring having a first groove-shaped race machined into an inner side of the outer bearing ring; an inner bearing ring having a second bearing race machined into an outer side of the inner bearing ring; and a plurality of ball rollers arranged between the bearing rings, the ball rollers have running surfaces and roll between the first groove-shaped race of the outer bearing ring and the second groove-shaped race of the inner bearing ring; and a bearing cage holding the ball rollers at uniform distances from one another in a circumferential direction, wherein the bearing cage is a window cage having two lateral cage flanges bent around two encircling flanging edges toward the inner bearing ring, a plurality of pocket webs being arranged to interconnect the cage flanges and form cage pockets that guide the ball rollers axially, wherein each of the cage pockets have a cross-hole shape formed from a cross-sectional contour of one of the ball rollers, which contour is arranged longitudinally with respect to the circumferential direction, and from a free contour, which is integrated in the cage pockets, arranged transversely to the circumferential direction and permits insertion of the ball rollers into the bearing cage, wherein the free contour in each of the cage pockets of the bearing cage has a rectangular shape, and wherein the flanging edges of the cage flanges each have a material thickness, which is reduced relative to a remaining material thickness of the bearing cage by an encircling linear rolled profile.
