Belted Air Spring

The belted air spring offers a higher load-bearing capacity than conventional air springs. It is primarily intended for use with bolstered bogies.

As an elastic link between the bogie  and railcar body, air bellows distance the railcar body to the platform and absorb track irregularities by minimising the transmission of vibrations.
