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.

Ball bearing and ball bearing assembly

A bearing seal is suitable for sealing a space between a first rotating body and a second rotating body of a bearing. The first radial end of the bearing seal is arranged on the first rotating body and forms a contact seal with the first rotating body, the second radial end of the bearing seal is arranged close to the second rotating body and forms a non-contact seal with respect to the second rotating body. A plurality of lubricant storage cavities arranged on the inner surface of the bearing seal facing the rolling elements of the bearing. A bearing providing the bearing seal as described above.

Bearing seal and a bearing with the same

A deep groove ball bearing having an inner ring, an outer ring and a plurality of rolling elements set between the inner and outer rings. The rolling elements have a diameter D≤0.5H, up to D≤0.35H. His the radial dimension of the bearing in the sense of thickness and is numerically equal to half of the difference between the outer diameter and inner diameter of the bearing.
