INTRODUCTION
Firestone developed the air spring in the late 1930’s as a more efficient spring (vibration isolator) for use in vehicle suspensions. Airide® springs, as they were named, provid- ed the means for a suspension to reduce the amount of road shock and vibration transmitted into the vehicle. Millions of miles of actual use have proven the dependabili- ty and effectiveness of the air suspension concept using Airide® springs by Firestone.
Airstroke® actuators, Airmount® isolators, and Airide® springs are Firestone registered trademark names for one product: the air spring. The use of the air spring (actuator, industrial isolator and vehicular isolator, respectively) deter- mines which name is applied to it. All of the parts in this catalogue may be used as Airstroke actuators (except the
Individual Airstroke actuators and Airmount isolators are capable of generating a force or supporting a load of up to 100,000 pounds, and a stroke capability of up to 14 inches is possible. Included in this engineering manual are detailed operating characteristics for many of the standard Firestone air springs, along with technical details and pro- cedures for using these products.
