Abstract

The invention relates to a seal arrangement for sealing off at least one radial interspace between at least one bearing ring which can rotate and at least one rotationally fixed bearing ring. The seal arrangement is provided with at least a first carrier, the first carrier carrying at least one resilient seal and being fixed to a rotationally fixed bearing ring, and a second carrier, the second carrier being fixed to the bearing ring that can rotate and carrying at least one encoder. The encoder has an outwardly oriented circumferential surface in the shape of a truncated circular cone.
