| description | A wheel bearing (12) is provided with a first ring (14), a second ring (20) which is mounted rotatably relative to the first ring via at least one greased rolling bearing (18), a sealing unit (24) arranged in the radial direction between the first ring (14) and the second ring (20), a further sealing unit arranged in the radial direction between the first ring (14) and the second ring (20), and a pressure chamber (36), wherein a supporting ring (40) for axially supporting the sealing unit (24) in the event of pressure in the pressure chamber (36) is arranged in the axial direction between the rolling bearing (18) and the sealing unit (24), wherein the supporting ring (40) forms an air gap (50), which is dimensioned for retaining lubricating grease of the rolling bearing (18), between the supporting ring (40), on the one hand, and the first ring (14) or second ring (20), which is rotatable relative to the supporting ring (40), on the other hand. As a result, a long service life for a rotary leadthrough (10) for a wheel bearing (12) is made possible. |
