A bearing has two coaxial outer support rings which are joined elastically by a radial bellows type member whose cross-section has at least one radial crease and which is not axially longer than either ring, and at least one cushioning stop is located beyond each crease. The bellows type member is made of thermoplastic elastomer; the cushioning stop extends radially from one ring towards the other and partially overlaps the crease concerned. ADVANTAGE - The design has a very long service life compared with that of existing designs. At the same time it also functions more effectively. In an example the two rings (1, 2) joined together radially by the bellows type member (3) which has axially disposed creases (3.1, 3.2) and has also cushioning stops (5, 6). These stops (5, 6) assume the positions shown dotted when the bearing is dismantled but, when heated and deformed recover the positions shown at right angles to the axis (7). The bearing preferably has a number of these stops (5, 6) round the circumference. They protect the creases (3.1, 3,2) from damage or mechanical stresses if the bearing is radially deflected severely.
