SEAL AND ROLLING BEARING COMPRISING SUCH A SEAL

摘要

The seal is designed to be mounted between two elements (14, 16) adapted to rotate relative to one another, notably rings of a rolling bearing, the seal comprising seal portions (32, 34) respectively capable of applying a dynamic seal with one of the two elements (16) and a static seal with the other element (14). The dynamic seal portion (34) comprises at least first and second lips (38, 40) delimiting an annular chamber (46) capable of being filled with lubricant. The seal is configured to allow, during the contact of a fluid with at least the dynamic seal portion (34), a movement of one of the lips, at least in the radial direction, in the direction of the associated element (16) to obtain a contact with the said element.
