The invention concerns a suspension thrust bearing for use with a suspension spring in an automotive suspension strut. The suspension thrust bearing provides a bearing with an annular upper part and a annular lower part in relative rotation one to the other, a lower support surface being provided by the lower part that axially supports an upper end of a suspension spring by the intermediate of a damping device made from resilient material. The resilient material of the damping device is molten in its preformed state with gas. After being molded, the molten material of the damping device provides an outer skinny layer and an inner foam body, the density of the outer skinny layer being strictly greater than the density of the inner foam body.

Suspension thrust bearing device

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.
