Abstract

A retaining element is disposed between two adjacent roller bodies of a roller bearing having an inner ring and an outer ring. The inner ring has an inner ring track with an inner radius and the outer ring has an outer ring track with an outer radius. Center points of the roller bodies are disposed along a pitch circle having a pitch circle radius. The retaining element extends radially inward from the pitch circle over at least 90% of the difference between the pitch circle radius and the inner radius and extends radially outward from the pitch circle over up to 50% of the difference between the outer radius and the pitch circle radius or vice versa.
