Unrestricted air spring with conical spring
Thanks to the large wall length of their bellows, unrestricted air springs are best suited to service in bolsterless bogies of high-speed trains and for modern bogies in urban and suburban transport systems. They allow all relative movements between vehicle body and bogie. |

Belted air spring with layer spring
Belted air springs are used in applications requiring max. load carrying capacity in a limited space. They are usually designed for bogies with a bolster. In combination with additional springs they also find application in modern bolsterless bogies used in mass transit trains. |

Rolling lobe air spring with half-hourglass
Under identical loading, rolling lobe air springs need slightly more installation space, but they permit somewhat larger lateral deflections with a lower design height. Fitted in series with a half-hourglass, they are suitable for bogies used in urban and suburban trains, especially in Jakobs bogies. |

Guided rolling lobe air spring with conical spring
Thanks to their compact design, guided rolling lobe springs permit the use of air spring systems even in confined spaces. Strengthened by a "stiffener", air springs can operate at more than 6 bar working pressure. This allows small outer diameters to achieve relatively high load carrying capacities. They are used in bogies of trams, especially low-floor types. |
