A cage (10) for holding rolling elements (9) of a roller bearing (6) comprises a frame part (15) holding the rolling elements (9) on a bearing circumference (17), and at least one circumferential sealing lip (16c, 16d) extending from the frame (15), made of a more pliable material than the material of the frame. The frame (15) has parts comprising concave surfaces (38). The material of the circumferential lip at least partly fills the concavities (25) defined by these concave surfaces.
