ABSTRACT:
An oil and grease-proof bellows for enclosing joints on axles of motor vehicles is produced from thin thermoplastic elastomers using hollow body production techniques. The bellows has a relatively small diameter collar, a collar of relatively large diameter, and a bellows device disposed between the collars, with an inner envelope and an outer envelope that decreases in diameter towards the smaller diameter collar. At least one bellows rib extends spirally from one collar to the other.
