Dear Ramesh

It has 3 part of bellow & two set of tie rod connected. Check vendor catalogue or ask for information from vendor. last time when I try to model this kind of bellow tie rod don't show good result in caesar, so I put effective ID of bellow as zero to remove pressure thrust effect, considering all pressure thrust will be taken care of tie rod combination of in line pressure balance bellow.
Note that this kind of bellow is highly costly & need longer space.
