Abstract

A bearing assembly includes at least first, second and third raceway elements that are each separable from each other and at least first, second and third rows of truncated-cone-shaped rolling elements. The first and second raceway elements are disposed side-by-side in an axial direction of the bearing assembly and oppoe the third raceway element in a radial direction of the bearing assembly. The first and second rows of rolling elements are disposed between the first raceway element and the third raceway element and the third row of rolling elements is disposed between the second raceway element and the third raceway element. The rolling elements of the first and second rows commonly roll on a first raceway of the third raceway element and the rolling elements of the third row roll on a second raceway of the third raceway element, which is not parallel to the first raceway.
