The invention relates to a ball bearing (1) provided with a bearing ring (3,4) and a cage (5, 35), in addition to at least one run-on surface (15) which is mounted on the bearing ring (3,4). The cage (5, 35) is provided with pockets (9, 41) which are adjacent to each other and which are arranged on the side of the periphery around the rotational axis (1a, 35a) of the ball bearing (1). Each pocket (9, 41) is defined in a demodulated axial first direction of the first edge (11, 36) by means of the axis of rotation (1a, 35a), in addition to being at least partially defined in at least one second direction of the second edge (12, 37) which is counter to the first direction, and at least one of the edges (11, 12, 36, 37) is defined in a radial direction by a radial guide surface (14, 45), whereby the guide surface (14,45) lies opposite the run-on surface (15) in at least a radially defined manner.
A ball bearing (1) with a bearing ring (3, 4) and with a cage (5, 35) and also with at least one run-on surface (15) on the bearing ring (3, 4), the cage (5, 35) being provided with pockets (9, 41) which are adjacent one another peripherally about an axis of rotation (1a, 35a) of the ball bearing (1) and each of the pockets (9, 41) thereby being at least partly delimited in an axial first direction, in the same direction as the axis of rotation (1a, 35a), by a first flange (11, 36) and in at least one second direction, counter to the first direction, by a second flange (12, 37), and at least one of the flanges (11, 12, 36, 37) being delimited in a radial direction by a radial guiding surface (14, 45) and the guiding surface (14, 45) thereby lying at least radially opposite the run-on surface (15), characterized in that radial distances (20a, 20b, 20c) between the axis of rotation (1a, 35a) and the run-on surface (15) that define the path of the run-on surface (15) become smaller as they become increasingly axially remote from a furthest distance (20) between the axis of rotation (1a, 35a) and the run-on surface (15), so that the run-on surface (15) slopes down in relation to the axis of rotation (1a, 35a) in an imaginary longitudinal section viewed along the axis of rotation (1a, 35a).
An angular-contact ball bearing (2) with a bearing ring (3) and a cage (5) and also with at least one annularly formed run-on surface (15) on the bearing ring (3), the cage (5) being provided with pockets (9) which are adjacent one another peripherally about an axis of rotation (1a) of the cage (5) and each of the pockets (9) thereby being at least partly delimited in an axial first direction, in the same direction as the axis of rotation (1a), by a first flange (11) and in at least one second direction, counter to the first direction, by a second flange (12), and at least the first flange (11) being delimited in a radial direction by a radial guiding surface (14) and the guiding surface (14) thereby lying at least radially opposite the run-on surface (15) and the second flange (12) thereby lying at least radially opposite a shoulder (8) on the bearing ring (3), characterized in that a smallest possible radial gap size between the guiding surface (14) and the run-on surface (15) is greater than zero, the smallest possible radial gap size being a smallest operating play between the rotating cage (5) in an operating state of the angular-contact ball bearing (2), and in that the gap size is less than a smallest possible further radial gap size between the second flange (12) and the shoulder (8).
