An embodiment of the present invention provides a wheel bearing assembly which mounts and supports a wheel of a vehicle on a vehicle body to be able to rotate. A wheel bearing assembly according to an embodiment of the present invention may include: a wheel hub having a wheel side mounting flange; and a brake disc mounted to the wheel hub. According to an embodiment of the present invention, a fastening unit for mounting the brake disc is provided on the wheel side mounting flange of the wheel hub, and the brake disc includes a sliding unit in frictional contact with the brake pad and a disc mounting unit extending inward in the radial direction from the sliding unit. According to an embodiment of the present invention, the wheel hub and the brake disc may be configured to be coupled to each other by mounting a fastening member in fastening holes provided in the fastening unit and the disc mounting unit in a state in which the fastening unit and the disc mounting unit are overlapped in an axial direction, and the fastening hole provided in the fastening unit may be configured to be formed in a shape different from the fastening hole provided in the disk mounting unit. The present invention can prevent a shake or a noise due to thermal deformation of the brake disk and enhance performance and service life of the wheel bearing assembly.
