According to an embodiment of the present invention, provided is a wheel bearing which rotatably mounts and supports a wheel of a vehicle on a vehicle body. According to an embodiment of the present invention, the wheel bearing can comprise: an outer ring unit supporting a rolling element from an outer side in a radial direction; an inner ring unit supporting a rolling element from an inner side in a radial direction; and the rolling elements arranged in a plurality of columns by being apart from each other in an axial direction between the outer ring unit and the inner ring unit. According to an embodiment of the present invention, the outer ring unit can include: a first outer ring unit having an orbit surface formed on an inner circumferential surface for the rolling element on a first column; a second outer ring unit having an orbit surface formed on an inner circumferential surface for the rolling element on a second column; and a spacer arranged between the first outer ring unit and the second outer ring unit. According to an embodiment of the present invention, the spacer can be configured so that an axial-directional cross-section on one side is coupled to the first outer ring unit and an axial-directional cross-section on the other side is coupled to the second outer ring unit, and so that the first outer ring unit and the second outer ring unit can be formed as a single integrated structure through the spacer.

    본 발명의 일 실시예에 따르면, 차량의 휠을 차체에 회전 가능하게 장착하여 지지하는 휠베어링이 제공된다. 본 발명의 일 실시예에 따른 휠베어링은 전동체를 반경방향 외측에서 지지하는 외륜부와; 전동체를 반경방향 내측에서 지지하는 내륜부와; 외륜부와 내륜부 사이에서 축방향으로 이격되어 복열로 배치되는 전동체를 포함할 수 있다. 본 발명의 일 실시예에 따르면, 외륜부는 내주면에 제1 열의 전동체를 위한 궤도면이 형성된 제1 외륜부와; 내주면에 제2 열의 전동체를 위한 궤도면이 형성된 제2 외륜부와; 제1 외륜부와 제2 외륜부 사이에 배치되는 스페이서를 포함할 수 있다. 본 발명의 일 실시예에 따르면, 스페이서는 일측 축방향 단면이 제1 외륜부에 결합되고 타측 축방향 단면이 제2 외륜부에 결합되어, 제1 외륜부와 제2 외륜부가 스페이서를 통해 하나의 일체형 구조로 형성되도록 구성될 수 있다.
