Abstract: A rolling body guide element for a roller bearing, having an inner web (1) that is arranged between two adjacent rolling bodies in the installed state and forms a first and second connecting part wall (1a, 1b) facing a respective rolling body at the radial plane of the rolling body axes, a run-on structure (2) formed in the region of the respective connecting part wall to provide at least one roller run-on zone supporting the respective rolling body in the circumferential direction, and a radial guide structure (3) for radial guidance of the inner connecting part. According to the invention, the rolling body guide element includes first and second side edge pieces (4, 5) which, on sides of the rolling body guide element facing away from one another, rise up above the end faces of the adjacent rolling body and overlap these end faces.
