A wheel bearing (10) is provided having a first ring (14), a second ring (20) which is mounted so as to be rotatable relative to the first ring (14) via at least one greased rolling bearing (18), a pressure chamber (22) which is formed in the radial direction between the first ring (14) and the second ring (20), and a sealing unit (12) which is arranged in the radial direction between the first ring (14) and the second ring (20) and in the axial direction between the greased rolling bearing (18) and the pressure chamber (22), wherein the sealing unit (12) has a sealing lip (26), which at least partially delimits the pressure chamber (22) axially, for air-tight sealing of the pressure chamber (22), and has at least one grease seal (36), which is different from the sealing lip (26), for grease-tight, but air-permeable sealing of an annular gap (24) formed between the first ring (14) and the second ring (20) and leading to the rolling bearing (18). The grease seal (36), which is separate from the sealing lip (26), makes it possible to avoid a wear-increasing carbonized layer due to lubricating grease of the rolling bearing (18), thereby making it possible to achieve a long service life for a rotary leadthrough for a wheel bearing (10).
