The invention relates to a seal assembly (24) for a wheel bearing (12) of a motor vehicle, comprising a seal retainer (26), which delimits a pressure chamber (36), the seal retainer (26) having an inlet channel (34) that can communicate with a pressure source and with the pressure chamber (36) and an outlet channel (54) that can communicate with the pressure chamber (36) and with a pressure useful space, and comprising a seal unit (38) arranged substantially coaxially to an axis of rotation (48) of the wheel bearing (12), for establishing a sealing contact with a sealing partner (50) that can be rotated relative to the seal retainer (26). The seal unit (38) delimits an axial end face of the pressure chamber (36) and can be moved relative to the seal retainer (26) in the axial direction and/or is elastically deformable. The flow cross-section of the outlet channel (54) is dimensioned in such a way that, when a pressure fluid is conveyed from the pressure source to the pressure useful space in the pressure chamber (36), a back pressure for sealingly pressing the seal unit (38) against the sealing partner (50) is caused. Thus, with low wear, a rotary feed-through (10) for a wheel bearing (12) having low leakage is enabled.
