Round Body Pneumatic Cylinders: When to Choose Them

A round body pneumatic cylinder has a plain round tube instead of a square profile. The slim, light body suits small machines and auxiliary movements where space and weight matter.

Small round cylinders usually follow ISO 6432. Fenitsa's catalogue starts at Ø32 with profile and CETOP series; round-body requirements are handled on request.
