Description convolution/ convoluted air spring

Complicated air springs are bellows-style GUOMAT air springs. Bellows air springs have one, two or three turns in a flexible member. Such double compound air bags are commonly used as lifting springs or axle trucks and trailers, as air springs and also as actuators or insulators in industrial and commercial applications and installations. 2B6273 specifications will vary, but the double curved GUOMAT bag can be found in the curly design and sleeve bellows. They will provide similar features and functions but a final permanent connection between the sleeve-type retainer and the braid and external replaceable component braid.
