Abstract

The present invention refers to a roller bearing (1) particularly suitable for use in seismic isolator, comprising a sliding plate (2) having a substantially circular bottom surface (3) intended for resting and rolling on a layer of balls (4), a boundary element (5) of the layer of balls substantially ring-shaped surrounding the bottom surface and having an internal knife-shaped edge and a f rustoconical ring-shaped interspace (7) for the accommodation and recirculation of the balls open towards the bottom surface.
