About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X220SU
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavier automation tasks with ease. The stainless-steel barrel and Ø12 mm rod shrug off mild corrosion and washdown environments better than painted alternatives. A 220 mm stroke operates at speeds between 30-800 mm/s, while fixed TPU bumper pads absorb the end-of-stroke impact. The U back cover provides a 90-degree port orientation for tight machinery layouts.
Equipped with a piston magnet (-S), the unit supports CMSG, DMSG and EMSG switches for position sensing. Driven by a 1/4" port and an M10x1.25 male rod thread, it yields a theoretical maximum of 82 kgf at 1.0 MPa. For practical sizing, plan for roughly 241 N of usable work at 0.5 MPa, which translates to safely lifting a 20.5 kg vertical load with a 2:1 margin.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G. Note: the Ø32 bore is a larger, non-ISO-6432 size.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X220SU Is Used
Package Diverting
Actuates heavy-duty routing gates on packaging lines, using its 402.2 N thrust to push dense cartons onto secondary chutes.
Stamping Ejection
Ejects formed metal blanks from small press dies, relying on the stainless construction to withstand light cutting fluid splash.
Pallet Stops
Raises and lowers pneumatic stop gates on roller conveyors, securely halting loaded pallets up to 20.5 kg during transit.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X220SU the Right Cylinder?
When sizing this 32 mm bore, compare it against its neighbours: a 25 mm bore generates 245.3 N push, whereas a 40 mm bore steps up to 628.3 N at 0.5 MPa. This model fits applications needing substantial force without jumping to the largest frame size. The 220 mm stroke is well within the 500 mm maximum, but at this extension length, verify your mechanical guidance to prevent rod bending under side loads.
Because it is a standard double-acting cylinder, the piston will drift if air pressure drops or the valve is centred—the TPU bumpers only decelerate the stroke end and do not function as a braking lock. To suspend a load safely mid-stroke, integrate an external pilot-operated check valve or a dedicated rod lock.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MI25~40 Stainless Steel Mini Cylinder MI32X220SU FAQ
This 32 mm bore cylinder uses a 1/4" air port. At 0.5 MPa it provides 402.2 N push and 345.6 N pull. At 0.7 MPa those figures rise to 563 N push and 483.8 N pull. The theoretical maximum force is 82 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in piston magnet compatible with CMSG, DMSG and EMSG reed or electronic switches. It features a U back cover that orients the air port 90 degrees, and the fixed TPU bumpers decelerate the stroke end without acting as an adjustable air cushion.
