A press connection which includes a carrier and at least one sleeve-shaped structural component of sheet metal seated at least with a press seat on the carrier. At least one indentation is formed on the surface of the carrier and the indentation is at least covered by at least one wall section of the sleeve-shaped structural component.

Press connection with a sleeve-like component of sheet metal

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.

Ball roller bearing

A ball roller bearing which has an outer and inner bearing ring and ball rollers arranged between the rings, which roll in groove-shaped tracks in the rings and are held at a uniform distance to one another by a window cage. The cage has two lateral angle ribs, pocket bridges, which connect the ribs and cage pockets separated by the pocket bridges. The pockets have a cross-shaped hole formed from a contour perpendicular to the circumferential direction and a cross-sectional contour of a ball roller arranged longitudinally to the circumferential direction. The side edges are formed from the pocket bridges, which have radii of arch-shaped guide surfaces corresponding to the running surfaces of two ball rollers. The pocket bridges have additional material profiling between the side edges and on the guide surfaces for axial stiffening of the cage and damping bearing noise.
