Abstract
A suspension thrust bearing (1) including at least one rolling bearing (7) forming an axial thrust bearing disposed on a lower cap (6) is provided. The lower cap (6) includes a body (8) with an annular rolling bearing portion (8a) for a spring (2) and a tubular portion (8d) including a bore (8e) in which a shock absorber bump stop (4) is inserted. An axial contact surface (8h) is defined on the lower portion of the bore (8e) of the tubular portion (8d) against which the shock absorber bump stop (4) when deformed exerts a radial force (F2). The tubular portion (8d) includes a reinforcing insert (10) located at the level of this axial contact surface (8h).
