2B9-273 Goodyear Air Spring Bellows Number 578923206 Metric M8 Nuts With 3/4 Air Inlet

Description of 2B9-273 Goodyear Air Spring:

This is a bellows-type Goodyear 2B9-273 air spring. The threaded metric M8 is used internationally. The bellows air spring has two turns in the flexible member. Such dual scroll airbags are commonly found on lift springs or axles of trucks and trailers, as air springs, and also as actuators or insulators in industrial and commercial applications. The specifications of your 2B9-273 will be different, but the double-pleated Goodyear bag is found in the pleated design and sleeve bellows. They will provide similar features and functions, but in the sleeve type, 2B9-273 permanently fixes the end fixture by pinching the flexible member between the end fixture and the external crimping ring.
