  • BALL BEARING AND BALL BEARING ASSEMBLY
    Publication number: 20240077105
    Abstract: A ball bearing includes an inner ring (1), an outer ring (2), and a ball (3). The inner ring (1) has an inner ring groove curvature radius Ri. The outer ring (2) has an outer ring groove curvature radius Re. The ball (3) has a ball diameter Dw. The ratio of the outer ring groove curvature radius Re to the ball diameter Dw satisfies: Re/Dw?0.5275; and/or the ratio of inner ring groove curvature radius Ri to the ball diameter Dw satisfies: 0.5175?Ri/Dw?0.55. The ball bearing may be accommodated in a housing, thereby forming a ball bearing assembly.
