Abstract
A ball bearing includes an inner ring (), an outer ring (), and a ball (). The inner ring () has an inner ring groove curvature radius Ri. The outer ring () has an outer ring groove curvature radius Re. The ball () 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.
