What they are

What are air spring bellows?

The bellows is the rubber part of the air spring, the flexible membrane that rolls over the piston and carries the load. In the AB series it is supplied on its own, without the top and bottom metal parts, which stay on the vehicle and are replaced independently.

Most of the NEOTEC AB range goes into bus suspension, reflecting how this design has traditionally been specified for that segment.

Where the metal parts need replacing as well, the same bellows is available complete in the ABK series.

Where they are used

Built mainly for buses.

The AB series is used above all in bus suspension, and in smaller truck applications alongside it. Bus suspension is where a bellows works hardest: less installation space, higher operating temperatures around the unit, and a duty cycle of constant stops rather than steady road miles.

01

Buses

The core of the AB range. Bus suspension puts the bellows in tight installation space and at higher operating temperatures, working through a stop-start duty cycle rather than steady kilometres.

02

Smaller trucks

Truck applications where the AB bellows is the specified replacement, with cross-reference data so the workshop can match the original without guesswork.

03

Same warranty, either way

NEOTEC does not shorten the warranty for harder applications. An AB bellows in a city bus carries the same cover of up to 3 years as one in a truck.
