SUSPENSION THRUST BEARING DEVICE

The invention concerns a suspension thrust bearing (1) for use with a suspension spring in an automotive suspension strut. The suspension thrust bearing (1) comprises a bearing (5) with an annular upper part (3) and a annular lower part (4) in relative rotation one to the other, a lower support surface (83) being comprised by the lower part (4) that axially supports an upper end of a suspension spring (2) by the intermediate of a damping device (8) made from resilient material. The resilient material of the damping device (8) is melt in its preformed state with gas. After being molded, the melt material of the damping device (8) comprises an outer skinny layer (85) and an inner foam body (84), the density of said outer skinny layer (85) being strictly greater than the density of the inner foam body (84).
