The crimped design allows for preshipment testing and quicker installation on equipment. Most Airstroke actuators feature Firestone’s proven concept of crimped end plates. This misalignment capability eliminates potential rod bending, scoring, and excessive seal wear common to conventional cylinders. FLEXIBLE MEDIAĪn Airstroke actuator can do its work with either a liquid or gas SIDE LOADING CAPABILITYĪirstroke actuators, within certain limits, are not affected by side loads as are conventional cylinders. This allows for the design of Airstroke actuators into applications where dirt or grit would destroy the seals on conventional cylinders.
NO MAINTENANCE OR LUBRICATION REQUIREDĪirstroke actuators have no internal rod, piston, or sliding seals as do conventional cylinders. The force capability is up to 100,000 pounds. Our smallest Airstroke actuator (2.2 inch/dia.) collapses to just 1.1 inches in height, while our largest triple convoluted Airstroke (37 inch/dia.) will collapse to a very compact 5.5 inches.Īirstroke actuators are available in sizes ranging from 2.2 inches to 37 inches in diameter. COMPACT STARTING HEIGHTĪirstroke actuators have a low profile compared to conventional cylinders. Angular motion of up to 30 degrees is possible, along with the design advantage of generally less complex linkages. Since Airstroke actuators have no sliding seals, there is no breakaway friction as with conventional cylinders ANGULAR CAPABILITYĪn Airstroke possesses the unique capability of stroking through an arc without a clevis. The long life and durability necessary for millions of miles of heavy duty suspension use under adverse environmental conditions are also important factors in machine design. DURABLE FOR LONG LIFEĪirstroke actuators are a further application of Firestone’s time proven Airide springs for truck and bus suspensions.
This initial cost advantage is many times greater in the larger sizes. Generally, initial cost is one-half or less than conventional pneumatic or hydraulic cylinders of the same force capabilities.
