Abstract
A spherical roller bearing providing an inner ring, an outer ring, rollers for rolling on raceways arranged on the rings, and a cage for holding the rollers spaced apart from each other. The cage having an annular core and a plurality of bars delimitating a plurality of pockets for the rollers, the annular core including two side faces from which the bars protrude axially outwardly, the inner and outer rings being rotatable with respect to each other around a bearing axis. The annular core further provides a plurality of spacing elements that protrude from the side faces of the annular core designed to come into contact with side faces of the rollers in order to prevent the rollers from moving axially towards the center of the bearing.
