摘要

The roller bearing has conical rolling bodies (7) rolling-up in a full arrangement between an inner conical path (2) and an outside conical path (6), where the rolling bodies are guided in a cage (8). The cage includes slots separated from each other by bars, where the rolling bodies are arranged in the slots. The bars include side surfaces facing the rolling bodies, where shaping of the surfaces is adapted to the rolling bodies. The bars are arranged radially outside of rotation axles of the rolling bodies. The rolling members are through-hardened.
