| 20120170885 | BALL ROLLER BEARING - A roller bearing which has an outer and inner ring and ball rollers arranged between the rings, which roll in two groove-shaped tracks in the outer and inner rings and are held at a uniform distance to one another by a window cage that has two lateral ribs bent around two circumferential flanged edges to the inner ring and interconnected by pocket bridges. The cage pockets of the cage ribs have a hole formed from a cross-sectional contour of a ball roller arranged longitudinally to the circumferential direction and from a free contour incorporated therein and arranged perpendicular to the circumferential direction. The free contour in each cage pocket is expanded to a rectangle and the flange edges of the ribs each have reduced material thickness compared to the other material thickness of the cage by a circumferential, line-shaped burnishing. | 07-05-2012 |
