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.

Typical Uses
- Small machines and auxiliary movements.
- Light pushing and sorting.
- Slim installations next to other units.
- Pivot mounting with rear clevis and rod-end eye.
Round vs Profile Body
Qualitative comparison.
| Round body | Profile body | |
|---|---|---|
| Typical standard | ISO 6432 (small bores) | ISO 15552 |
| Sensors | Band clamps | Slots in the profile |
| Space | Slim, light | Square section |
| Fenitsa range | On request | FMY Ø32–Ø320 |
How to Choose
- For Ø32 and above, compare with the FMY profile series first.
- For sensor positions along the stroke, a profile body is easier.
- Send stroke, force and mounting to get a round-body offer.
