The invention relates to a suspension thrust bearing device (10) for a suspension spring (3) in a motor vehicle suspension strut of a vehicle. The device comprises a bearing having an upper annular bearing member (20, 41) and a lower annular bearing member (30, 42) that rotate relative to each other, the lower annular bearing member comprising a radial body (32). The device further comprises a damping element (50) having a damper radial portion (52) made of an elastic material and overmoulded to the radial body (32) of the lower annular bearing member, the damping element (50) having a lower support surface (53) for axially supporting the end coil of the suspension spring (3). The damper radial portion (52) has material hardness between 50 Shore A and 85 Shore A, and the damper radial portion (52) has axial thickness (D52) between 2 mm and 10 mm.
