Firestone airmount4/11/2023 CONSTANT ISOLATION EFFICIENCYĪirmount isolators are unique in that the system’s natural frequency does not change significantly with changes in load. This unique feature, combined with accurate height control, will allow the use of the same Airmount isolator at each mounting point of an unevenly loaded machine. Airmount isolators are also quiet in themselves, since there is no spring chatter as found in conventional coil springs.Īirmount isolators are unique in that the system’s natural frequency does not change significantly with changes in load. EFFECTIVE NOISE REDUCTIONĪirmount isolators reduce structurally transmitted noise. Coil springs providing equal isolation would require a free height of 5 to 25 inches. COMPACT INSTALLED HEIGHTĪirmount isolators can carry the loads and provide the isolation described above at installed heights as low as 2.5 inches. This feature eliminates the fatigue and permanent set found in the use of other types of vibration isolators. ACCURATE HEIGHT CONTROLĪirmount isolators provide accurate height control through regulation of internal air pressure. In order to achieve similar results from a conventional coil spring isolator, a real deflection of 9 inches would be required. The addition of an auxiliary reservoir can provide even lower system frequencies. System natural frequencies as low as 60 cycles per minute (1 Hertz) are available. UNSURPASSED ISOLATION CAPABILITYĪirmount isolators can provide the highest degree of isolation of any type vibration isolator. Imperial catalog Metric catalogĪirmount isolators can provide the highest degree of isolation of any type vibration isolator. 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.
