An axle assembly includes a bearing axle that rotatably supports a bearing, which may be a plain bearing.

The bearing assembly comprises a spherical plain bearing (130) and a mounting structure (122) for receiving the spherical plain bearing.

A thrust bearing is disposed between the upper journal bearing and the lower journal bearing.

The upper bearing is a roller taper bearing and the lower bearing is a journal bearing (18) consisting of an outer sleeve of an elastically deformable plastic material and an inner bearing bushing of a bearing metal.

The annular structure and the receiving means (8) form the bearing and the radial bearing is a sliding bearing, whereby means of the receiving element are arranged in a directly gliding manner on a wall of the annular structure.

A sliding bearing is used for the orbiting bearing part and the main bearing part.

The bearing system includes a sliding bearing (1).

The radial inner side of the composite bearing is a centripetal sliding bearing (13), and the lower end of the composite bearing is a thrust bearing (14).
