About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X80SUTC
Delivering 402.2 N of push force at 0.5 MPa, this AirTAC MI32X80SUTC actuator is a robust round-body mini cylinder built for demanding automation. The stainless-steel barrel and Ø12 mm rod shrug off mild corrosion, making it highly suitable for damp washdown environments where painted steel alternatives degrade. A built-in piston magnet (-S) supports CMSG, DMSG and EMSG switches for exact position detection.
This double-acting unit features a 1/4" port and fixed TPU bumper pads that absorb stroke-end impact without the complexity of adjustable cushioning. Plan for a safe working load of roughly 241 N, which means it can comfortably lift about 20.5 kg vertically with a 2:1 safety margin. The U back cover provides a 90-degree port orientation, while the included TC trunnion mount simplifies pivot integration.

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 MI32X80SUTC Is Used
Package Diverting Gate
Swings a heavy routing gate on a packaging line, using the 402.2 N thrust to push assorted parcels reliably without stalling.
Pallet Stopper Arm
Acts as a robust pneumatic stop for loaded pallets entering a stretch wrapper, absorbing impact via the fixed TPU bumper pads.
Clamp Actuation
Secures metal castings during a CNC milling process, where the stainless construction resists cutting fluid splashes.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X80SUTC the Right Cylinder?
When sizing this 32 mm bore, the smaller Ø25 MI generates 245.3 N of push at 0.5 MPa, whereas stepping up to the Ø40 MI yields 628.3 N. If your application requires a held position during air loss or valve centering, remember that this standard cylinder will drift; you must add an external rod lock or pilot-operated check valve for secure load holding. The fixed TPU bumpers only decelerate the stroke end, they do not act as a brake.
The 80 mm stroke sits well within the 500 mm maximum standard limit, keeping the rod bending risk low even under dynamic side loads. For high-speed cycles generating significant kinetic energy, consider the MIC variant which offers variable air cushioning. This SKU includes the -S magnet for sensors and uses the TC trunnion alongside the U back cover for flexible mounting.
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 MI32X80SUTC FAQ
This 32 mm bore cylinder features a 1/4" port and generates a push force of 402.2 N and a pull force of 345.6 N at 0.5 MPa. At 0.7 MPa, push increases to 563 N and pull to 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
Yes, the -S suffix denotes a built-in piston magnet compatible with CMSG, DMSG and EMSG switches. The included TC trunnion mount allows pivoting, while the U back cover orients the air port at 90 degrees. Note that Ø32 is a non-ISO-6432 round-body size.
