<p>The spring has a working chamber that is partly enclosed by a pneumatic spring bellow which is made of elastomer material. The pneumatic spring bellow forms a roller fold at one of ends. The bellow is firmly connected with a pneumatic spring piston and two pneumatic spring covers (D) at respective ends. A connection is formed between the bellow and the covers from multiple bearing packages consisting of circular bearing parts. The diameter of the circular bearing parts corresponds to the effective diameter of the spring. The circular bearing parts are made of rubber.</p> |
