A suspension thrust bearing including at least one rolling bearing forming an axial thrust bearing disposed on a lower cap is provided. The lower cap includes a body with an annular rolling bearing portion for a spring and a tubular portion including a bore in which a shock absorber bump stop is inserted. An axial contact surface is defined on the lower portion of the bore of the tubular portion against which the shock absorber bump stop when deformed exerts a radial force. The tubular portion includes a reinforcing insert located at the level of this axial contact surface.
