Abstract
An axial joint arrangement with integrated seal is provided with three successively arranged bearing rings, the upper and lower bearing rings having spherical guiding surfaces which oppose corresponding spherical surfaces of the middle bearing ring. The upper and lower bearing rings are connected and the middle bearing ring slides therebetween. The guiding surface of the lower bearing ring serves to center and guide the middle bearing ring and the guiding surface of the upper bearing ring serves to transmit operating loads to the middle bearing ring. A first sealing disk is attached to the middle bearing ring. One face of the first sealing disk abuts a first sealing surface and the other face abuts an intermediate disk. The intermediate disk is sealingly connected by a bellows to a second sealing disk, which is in turn connected to a second sealing surface.
