    摘要: A rolling bearing cage provides a circumferential spacing of a row of rolling elements and comprises first pockets configured to accommodate first rolling elements of the row of rolling elements. The first pockets are provided with axial retention portions configured to retain the rolling bearing cage on the first rolling elements. Second pockets are configured to accommodate second rolling elements of the row of rolling elements and not provided with axial retention portions configured to retain the cage on the second rolling elements. Separation portions are provided which between the separation portions delimit the first and second pockets. Each of the separation portions delimiting one of the first pockets comprises a notch open in an axial direction and open in opposing radial directions.

    摘要: The rolling bearing comprises an inner ring, an outer ring, at least one row of rolling elements disposed between raceways provided on the rings, and an annular housing inside which at least one of the rings is arranged. The ring provides two parts and each of the two parts delimits with the housing a closed space inside which a lubricant is located. The rolling bearing further comprises passage means for the lubricant to pass from the closed spaces to the raceways.The ratio between the thickness of a guiding portion of each of the two parts delimiting the raceway and the outer diameter of the bearing is from 0.7% to 3%.In a second embodiment, the ratio between the thickness of the guiding portion and the outer diameter is and preferably from 1.1% to 1.9%.

    摘要: A cage for a rolling bearing, wherein the cage is intended to ensure the circumferential spacing of a row of rolling elements. The cage comprises pockets for the rolling elements and connecting portions, each connecting portion connecting two successive pockets. At least one of the connecting portions is elastically deformable at least in a circumferential direction so as to allow the two associated pockets to move relative to one another in the circumferential direction.
