摘要

The suspension strut bearing (4) has an intermediate portion (9) of plastic material with an upper portion (2), where the intermediate portion forms a hard component (10) and a soft component (11). The hard component is formed on a bearing ring (5), while a dynamic sealing contact is formed against a lower portion (3) by the soft component. A dirt deflector (17) of a sealing unit (12) is provided on the hard component. The soft component has a sealing lip (14) in contact with the lower portion and an annular lip (15) that is extended radially outward relative to the sealing lip. An independent claim is included for a suspension strut with a sealing gap formed by the dirt deflector with the annular edge of the lower portion.
