1. An assembly comprising:
a housing having a bore defined by a cylindrical inner surface,
a shaft radially supported in the bore by a radially supporting rolling-element bearing, and
an axially supporting rolling-element bearing mounted on the shaft in the bore, the rolling-element bearing comprising:
at least one inner ring,
at least one outer ring, and
a plurality of rolling elements disposed in a bearing interior between the at least one inner ring and the at least one outer ring,
wherein the at least one inner ring includes at least one raceway on a radially outer surface,
wherein the at least one outer ring includes at least one raceway on a radially inner surface facing the at least one raceway of the at least one inner ring and at least one radially outwardly facing opening on a radially outer surface,
wherein at least one seal element is mounted in the at least one opening, the at least one seal element including at least one seal lip,
wherein the at least one seal element includes a first seal element having a base section and a seal lip projecting from the base section, an inner end of the seal lip of the first seal element being located at the base section and an outer end of the seal lip of the first seal element being separated from the base section by a seal lip gap, and
wherein the seal lip of the first seal element projects outward from the at least one opening in a direction having a radial component,
wherein the seal lip of the first seal element is in contact with the cylindrical inner surface,
wherein the radially outermost surface of the at least one outer ring is spaced from the cylindrical inner surface by a radial gap, and
wherein the direction has an axial component.
