Suspension strut bearing device having a cover and a guide ring which is rotatable relative to the cover, wherein the cover and the guide ring form a detachable snap connection by means of a snap connection, a bearing and at least two sealing means for sealing the bearing being provided between the cover and the guide ring, the sealing means being fixed on the cover and forming a dynamic seal with the guide ring, wherein at least one sealing means is provided between the bearing and the snap connection, the guide ring having a sealing area for forming a seal with the at least one of the sealing means,

the sealing device is characterized in that the sealing area is a continuous smooth curved surface which can be divided into three parts, namely a non-contact inclined surface, a contact arc surface and a side inclined surface in sequence from large to small according to the distance between the sealing device and the cover in the axial direction, wherein at least one sealing device abuts against the contact arc surface, and the side inclined surface is positioned between the at least one sealing device and the bearing in the radial direction.

The suspension strut bearing assembly of claim 1, wherein the non-contact ramp is angled from 5 ° to 25 ° relative to horizontal and tangent to the contact arc.

The suspension strut bearing assembly of claim 1, wherein the contact arc has a radius of 2 to 5mm and is tangent to the non-contact ramp and the side ramp.

The suspension strut bearing assembly of claim 1, wherein the side slope is angled from 55 ° to 75 ° from horizontal and tangent to the contact arc.

The suspension strut bearing assembly according to claim 1, wherein a protrusion extending axially toward the cover is provided between the seal region of the guide ring and the bearing, and the side slope constitutes an outer surface of the protrusion on the side of the seal region.

The suspension strut bearing assembly of claim 5, wherein the protrusion is spaced axially from the cover by a sufficient distance such that the distance ensures that the protrusion does not contact the cover during operation of the suspension strut bearing assembly.
