About Goodyear air springs:
Goodyear air springs are highly durable, sophisticated and
cost-effective for a variety of drive and vibration isolation
applications. Goodyear air springs feature a time-tested design
that combines fabric-reinforced cord or natural rubber flexible
member construction with corrosion-resistant end iron plate cover
retainers to provide superior quality and performance. As
corrective actuators, Goodyear air springs can provide linear or
angular motion.
Goodyear offers a variety of air spring and air shock absorber
types to suit your actuation or isolation needs. Single, double and
triple convolution bellows, rolling cam and sleeve types are
available in a variety of sizes, and end retainer styles need to
fit your specific installation.
These air springs (air shock absorbers) offer a favorable
stroke-to-compression height ratio compared to cylinder or steel
springs, and they can accept various drive media such as air,
water, nitrogen or other liquids. As isolators, Goodyear air
springs can effectively reduce the adverse effects of vibration.
They can both isolate vibrations and adjust the load height. Allows
for consistent vibration isolation under different loads as the air
pressure varies.
