Abstract

DYNAMIC SEALING DEVICE The invention concerns a dynamic sealing device configured to provide sealing between at least a first part and at least a second part having a relative rotational movement in relation to the first part. The device comprises a seal provided with a first lip and with a second lip extending from a body portion, the first lip facing the second lip, the seal being formed from a first predetermined material having a first coefficient of friction, and a ring formed from a second predetermined material different from the first predetermined material and having a second coefficient of friction different from the first coefficient of friction. According to the invention, the device is characterized in that the ring is securely connected with the seal at the location of the body portion and in that the first coefficient of friction of the first predetermined material forming the seal is greater than the second coefficient of friction of the second predetermined material forming the ring.
