Airstroke Actuators Offer Simple Solutions.
Product/Service Name
Firestone Airstroke Actuators
Airomatic Actuator
Function/ApplicationsThe actuation alternative offer by pneumatic actuation and isolation specialists Air Springs Supply Pty Ltd involves some of the very simplest pneumatic actuators available.
Firestone Airstroke® actuators, which are tough, flexible wall bellows engineered into different shapes to perform different tasks. They contain no internal moving parts to break, bend, cause internal scoring or require lubrication.
Another of their advantages for conveyor applications is side load flexibility. Because an air spring has a flexible, compliant bellows wall, instead of seals or guides, the bellows follows the path of least resistance. This means users don't have to worry about side loads caused by misalignment.
The lack of seals also means lack of friction. Because Airstroke actuators have no sliding seal, there is no breakaway friction as with conventional cylinders.
Airstrokes also possess the unique capability of stroking through an arc without a clevis. Angular motion of up to 30 degrees is possible, along with the design advantage of generally less complex linkages.
Airstrokes can offer considerable performance and cost benefits for many high-speed operations and those requiring reliable performance in aggressive environments.
Airstorkes can be used instead of more expensive hydraulic systems, for example, when applying large forces, or slower and bulkier conventional metal sleeve cylinders.
Airstroke sizes are available from about 31 mm diameter (2.2 in) to 940mm (37 in). The smaller sizes provide a wide range of forces required for conveyor and processing operations, while the largest sizes allow force up to 40,000 kg each using only 7 bar (100psi) air pressure. Yet the capital cost of an air spring is normally less than half that of an hydraulic or pneumatic cylinder with equivalent capabilities.
