Claim:
1. A rolling-element bearing comprising: a first bearing ring, a second bearing ring, and a seal unit formed in a multiple-piece manner, wherein the seal unit comprises an at least part-ring shaped main element which is freely rotatable with respect to the first bearing ring and the second bearing ring, and at least one seal lip, wherein the main element and the seal lip are exchangeably connectable to each other, wherein the seal lip is rotatable with respect to the first bearing ring or the second bearing ring and is attached to the main element; wherein the seal lip includes a seal surface for sealing against the first bearing ring or the second bearing ring which is in sliding contact with the first bearing ring or the second bearing ring, wherein a rotational speed of the freely rotatable main element is determined by frictional forces occurring between the seal lip and the first bearing ring or the second bearing ring due to the sliding contact of the seal lip with the first bearing ring or the second bearing ring, and wherein the first bearing ring and the second bearing ring are tiltable by a limited angle with respect to each other.
