Lateral Stability

Paraphrased from Continental’s website:

The lateral stiffness of air bellows differs greatly from type to type. For the individual air bellows types, the following lateral stiffness values – relative to the axial stiffness – can be expected. The specified percentages are for the recommended operating height for vibration isolation.

 

Single convolution 30 to 60%

Double convolution 5 to 30%

Belted 30 to 50%

Triple convolution 0% (not recommended)

Rolling lobe 0% (without restraining cylinder)

Sleeve type 0% (without restraining cylinder)
