Abstract
A lubrication seal such as an oil seal is described for providing a lubrication barrier to confine lubrication in a bearing with a first bearing ring and second bearing ring, comprising a support ring that rotates with one of the bearing rings, mounted in the support ring are a first seal ring and a second seal ring which seal rings are suitable for forming the lubrication barrier with a sealing surface that rotates with the other bearing ring and which support ring is displaceable from a first sealing position in which the first seal ring forms the lubrication barrier with a first sealing area and the second seal ring does not engage the sealing surface to a second sealing position in which the second seal ring forms the lubrication barrier. The sealing surface comprises a second sealing area that only cooperates with the second seal ring after the support ring is displaced into the second sealing position.
