Abrégé

The present invention relates to a bearing arrangement comprising two bearing members, between which rolling bearing rings comprising two rolling elements are arranged. On one of the two bearing members, a projection with a tip pointing radially towards the remaining bearing member is arranged. The tip lies between two oppositely inclined truncated cone lateral surfaces, on each of which truncated cone lateral surfaces forming first rolling element running surfaces the rolling elements of a rolling bearing ring roll. Two V (fillet) grooves are recessed into the remaining bearing member. A rolling bearing ring is arranged axially on both sides of the projection. A support ring is arranged axially on both sides of the rolling bearing rings. The support rings each have a truncated cone lateral surface-shaped support surface which, together with the first rolling element running surfaces, form the groove walls of two two-part V (fillet) grooves. On one side of one of the support rings, at least one support surface on the bearing member side is arranged on one of the two bearing members, against which the one support ring is arranged in axial contact.
