Why use an Airstroke actuator (rather than air or hydraulic
cylinder)for actuation?
LOW COST
Generally, initial cost is one-half or less than conventional
pneumatic or hydraulic cylinders of the same force capabilities.
This initial cost advantage is many times greater in
the larger sizes.
WIDE SIZE RANGE
Airstroke actuators are available in sizes ranging from 2.2 inches
to 37 inches in diameter.
The force capability is 100,000 pounds. Strokes of up to 14 inches
are possible.
DURABLE FOR LONG LIFE
Airstroke actuators are a further application of Firestone’s time
proven Airide springs for
truck and bus suspensions. 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.
