Firestone Airstroke range of actuators from Air Springs Supply

Supplier News

Air Springs Supply ’s Firestone Airstroke range of actuators is seen as one of the solutions to overcome the need to constantly lubricate and protect actuators in conveyor systems operating in grimy and aggressive environments.

Working on the reasoning that fewer moving parts are better, one solution for simplicity and reliability can be to employ Airstroke actuators which have no seals, shafts or internal moving parts

These enormously tough rubber and fabric actuators are, in effect, balloons or bellows engineered to particular shapes for particular tasks. They are rapidly inflated and deflated to provide the actuation and retraction required by modern high-speed conveyors employed in heavyweight industries ranging from mining, materials handling, waste water and minerals processing through to more delicate tasks in the food, chemicals and manufacturing areas.

Supplying actuation forces from a few dozen kilograms up to 40,000kg a unit, Airstroke’s single, double and triple-convoluted and rolling sleeve designs are made exactly the same way as the air springs used as suspension springs in heavy vehicles such as semi-trailers. The compact but powerful actuators are every bit as tough as the Airmount isolators found under giant semi-trailers hauling coal, minerals and heavy grimy loads day after day, year after year

Air Spring Supply’s Firestone Airstroke offering ranges from the largest models down to palm-sized Airomatic mini actuators for delicate jobs requiring a clean actuator that doesn’t need lubrication and can cope effortlessly with high-repetition tasks. These are available throughout Australia.

Being made of rubber and not having any rods or seals to damage, they allow maintenance-free deflection on a continuously basis. Their flexibility also makes them ideal for applications such as belt takeups or roller friction applications, where they may be applied against an oscillating surface

They can also stroke through a radius without a clevis, thus eliminating both complexity and cost when you need to actuate through an angle. Their ability to soak up shock without damage while delivering high-repetition strokes means they are highly applicable to conveyor transfer, gate and lift sections.

Air Springs Supply’s growing Airstroke range offers actuation strokes ranging from 12.5mm for the tiny (16mm high deflated) Airomatics, through to more than 300mm for triple-convoluted models used as both actuators and isolators in heavy industry.
