Air Springs for Vibration Actuation

AIR ACTUATORS:

Air actuators can be used instead of pneumatic or hydraulic cylinders in a wide range of applications. Air actuators can be used in nearly all branches of industry. Ideal for applications with adverse ambient conditions and high force requirements. Some applications include:

  • vehicle applications
  • materials handling equipment
  • agricultural machinery
  • food industry
  • paper and textile equipment
  • punch and forming presses
  • sawmill machinery

They have effective diameters of between 60 mm and 950 mm, can execute strokes up to 455 mm and can exert forces of between 0.5 kN to 440 kN.

Benefits

  • Non-wearing = maintenance-free
    Air actuators perform efficiently even when operating in difficult conditions. The actuator has no
    parts that rub against each other (sealing elements), so the product does not wear, even under adverse conditions such as dirt, dust, granular materials or sediments.
  • Great durability
    Dynamically, air actuators are highly durable. They are unaffected by weathering, environmentally induced factors and numerous chemicals. Their materials have been tried and tested in the production of commercial and passenger vehicles as well as rolling stock. They have a long service life even when subjected to large loads.
  • Extensive product range
    air actuators can be used instead of pneumatic cylinders in a wide range of applications. They have effective diameters of between 60 mm and 950 mm, can execute strokes up to 455 mm and exert forces of between 0.5 – 440 kN.
  • No friction = smooth operation
    air actuators have no parts or seals that move against each other. Consequently, there is no breakaway friction to overcome (stick-slip-effect), so the actuators respond immediately and uniformly even to small variations in pressure.
  • Lateral misalignment possible
    air actuators will continue to operate reliably with a misalignment of up to 20 mm. Unlike actuators based on pneumatic or hydraulic cylinders, air springs have no seals that are subject to blockage or wear. In addition, there is no need for precision guides which are sensitive to the effects of dust and other contaminants.
  • Easy economic installation
    When unpressurized, air actuators can be installed quickly and easily, thereby saving time and money. They are flexible enough to compensate for any slight misalignments.
  • High operational safety
    air actuators can operate with oil-free compressed air and can therefore be used for special applications, e.g. in the food industry. As stipulated by safety standards, the burst pressure is several times greater than the maximum working pressure.
  • Resistance to various media
    Although designed primarily to be operated pneumatically using compressed air, air actuators can be operated equally well with other gaseous media such as nitrogen. At low pressures, hydraulic media such as water and glycol can be used as well.
  • Low design height
    In comparison to conventional pneumatic cylinders, air actuators contain no piston rod, making it possible to reduce the design height considerably. This allows compact constructions to be made.
  • Tilt motion without adapter
    Depending on the type, air actuators can be used for tilt angles up to 30°. This enables the designer to simplify the articulated construction.
  • Low purchasing costs
    The purchasing costs are considerably less than for conventional pneumatic cylinders. And thanks to the long service life and freedom from maintenance, running costs are reduced as well.
