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.
