Abstract: A rolling-element bearing assembly includes a first bearing ring and a second bearing ring that define a bearing interior between them, a plurality of rolling elements disposed in the bearing interior to allow a relative rotation of first and second bearing rings, and a seal assembly for sealing the bearing interior. The seal assembly includes a seal carrier that is connected to the first bearing ring such that they rotate together and a seal element that is connected to the seal carrier such that they rotate together, and the seal carrier comprises a fiber-reinforced plastic.

Abstract: A rolling-element bearing assembly includes first and second bearing rings that form a bearing interior between them and a plurality of rolling elements disposed in the bearing interior and a seal assembly for sealing the bearing interior. The seal assembly includes a seal carrier and a seal element having at least one primary seal lip for sealing the bearing interior and a secondary seal lip for sealing against external contamination. The seal element is connected to the seal carrier such that the primary seal lip and the secondary seal lip abut axially against an axial end surface of the second bearing ring.
