Abstract

Un anillo de cojinete (30) para un cojinete de rodillos con una vía de rodadura (14; 15) para al menos un rodillo de rodamiento (13) y un borde (31) dispuesto para la desviación de fuerzas axiales en un lado frontal de la vía de rodadura, que se extiende fuera de la vía de rodadura y presenta una superficie de tope (32) dirigida hacia la vía de rodadura (14; 15) para rodillos de rodamientos (13), cuya curvatura cae estrictamente monótona desde un punto de partida (33) hasta un extremo (34) de la superficie de tope, en el que el punto de partida (33) está dispuesto entre un extremo interior (36), adyacente a la vía de rodadura, de la superficie de tope (32) y un extremo exterior (34), alejado de la vía de rodadura, de la superficie de tope (32), y la curvatura de la superficie de tope (32) cae, respectivamente, estrictamente monótona desde el punto de partida (33) hacia ambos extremos de la superficie de tope (32) o en el que punto de partida (33) está dispuesto en el extremo interior (36), adyacente a la vía de rodadura, de la superficie de tope (32).
