Convoluted air springs
Classified as single, double and triple; convoluted air springs increasingly replace pneumatic cylinders in the world industry. With higher course length, compactness, ease of usage and low maintenance costs, convoluted air springs offer the performance in lifting, compression, suspension and eliminating vibration both under vehicles and machines.
Although the two-ply air spring is standard, many of our air springs are also available in four ply construction for use at higher pressures. If you have any requirments, please feel free to contact us.
