Abstract

The roller bearing comprises an inner ring, an outer ring, at least one row of rolling elements which are arranged between the rings in order to form an axial thrust which can transmit axial forces, and a row of rolling elements arranged between the rings in order to form a radial thrust which can transmit radial forces. The inner ring comprises an annular groove which extends towards the interior from an outer surface of the ring, and forms a raceway for the rolling elements of the radial thrust.
