Air Bellows

Air bellows are the ideal choice and can be used in a number of applications, including high force over a short stroke length, vibration dampening and providing tipping moments. Manufactured from fabric reinforced synthetic rubber in one, two or three convolutions according to stroke and model. They incorporate no reciprocating metal parts and so provide virtually frictionless thrust compared with conventional pneumatic cylinders. All models are single acting only.

The return stroke is provided in part by the natural spring action of the bellows but more usually by the load itself. The simplicity of construction provides an extremely long, virtually maintenance-free service life even under arduous conditions. Air bellows offer a maintenance free, lubrication free option with almost frictionless operation.

FEATURES

  • High thrust and frictionless movement
  • No maintenance or lubrification, oil free
  • Short stroke for high force application
  • Easy to install, no precise alignment
  • Easy to work
  • Single acting use as a cylinder
  • High isolation level, use as an isolator
