Abstract
A bearing includes two hollow cylindrical prop rings coaxially surrounding a central axis. A bellows element formed from a thermoplastic elastomer material elastically couples the prop rings in the radial direction. The bellows element has a radially extending profile that includes at least one fold protruding in the axial direction. The bellows element also has an axial length that does not overlap the axial length of said prop rings. At least one bumper is provided axially outside the axial length of the fold. The bumper has a profile that radially extends, during normal operational use, from at least one of the prop rings in the direction of the other prop ring. The bumper and the fold partially overlap.

A bearing comprising:
- two hollow cylindrical prop rings coaxially surrounding a central axis;
- a bellows element formed from a thermoplastic elastomer material elastically coupling said prop rings in the radial direction, the bellows element having a radially extending profile that includes at least one fold protruding in the axial direction and having an axial length that does not overlap the axial length of said prop rings;
- at least one bumper provided axially outside the axial length of the fold, said at least one bumper having a profile that radially extends, during normal operational use, from at least one of said prop rings in the direction of the other prop ring, said bumper and said fold partially overlapping.
