For all flexible elements to perform efficiently, it is imperative that the Bellow component of the integrated assembly is designed to meet the engine working conditions. While designing the Bellow, the actual working parameter which includes the gas temperature, pressure and movement is taken into consideration.

Improper design of the Bellow would invariably lead to premature failure and therefore the Bellow design is directly linked to the performance of the flexible element assembly.
