Half Bellow

Half bellows for bolster-less bogies enable vast lateral deformation. For high-speed trains and modern bogies in local and metro transportation.

As an elastic link between the bogie  and railcar body, half bellows distance the railcar body from platform irregularities by minimizing the transmission of vibrations.

Half Bellow


  • Highest driving comfort, regard-less of loading
  • When following a curve in the track,  they enable lateral deflection in the bogie
  • With a constant, adjustable height, the railcar body can maintain an ideal distance from the platform


  • Diameter: ~ø510-830mm
  • Vertical loads: up to 190kN
  • Lateral deflection: up to ±140mm (up to ±160mm possible) in air spring system
  • Operating pressure range: 2-6 bar
  • Operating temperature: -45°C (-50°C) up to +65°C (+70°C)
  • Some types available in EN 45545 (fire& smoke protected)
