Abstract

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.
