2B9-218 Goodyear Lift Springs Or Axles For Trucks And Trailers Flexmember 578923206 Airbag
Description of 2B9-218:
This is a bellows style GUOMAT air spring. The bellows air spring has one, two or three windings in the flexible member. Such double-turn airbags are commonly used in lift springs or axles for trucks and trailers, as pneumatic springs, and as actuators or insulators in industrial and commercial applications. The specifications for 2B9-218 will vary, but the double-curved GUOMAT bag has a crimp design and a sleeve bellows. They will provide similar features and functions, but the sleeve type permanently connects the end retainers by clamping the flexible member between the end retainer and the outer crimp ring.
