SUSPENSION THRUST BEARING DEVICE AND SUSPENSION STRUT EQUIPPED WITH SUCH A DEVICE

A suspension thrust bearing device for use with a suspension spring in an automotive suspension strut of a vehicle includes a bearing having an upper annular bearing member and a lower annular bearing member configured for relative rotation. The lower annular bearing member has a radial surface and a resilient damper overmolded to the radial surface, which damper has a lower support surface configured to axially support an end coil of the suspension spring. The lower support surface has at least one high portion and at least one low portion that form a waveform, such as a square wave or a sinusoidal wave, in a peripheral direction.
