About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X125SUTC
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MI32X125SUTC is a robust double-acting round-body mini cylinder built for demanding automation. Its stainless-steel barrel and rod shrug off mild corrosion, making it highly suitable for damp washdown environments where painted alternatives fail. The 1/8" port feeds the 32 mm bore efficiently, while fixed TPU bumper pads absorb the impact at stroke ends.
Because the 402.2 N rating represents an ideal maximum, you should plan for a safe working load of roughly 241 N to account for friction and real-world dynamics. In vertical lifting scenarios, this translates to hoisting about 20.5 kg safely with a 2:1 margin. This SKU includes a built-in piston magnet for CMSG, DMSG, or EMSG position sensing.

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 MI32X125SUTC Is Used
Stamping Pin Ejection
Uses the 402.2 N push force at 0.5 MPa to eject stamped metal pins from a die, leveraging the 125 mm stroke to clear the press bed entirely.
Heavy Package Diverting
Actuates a pivot arm on a packaging line to reroute dense cartons, taking advantage of the stainless construction to endure humid warehouse conditions.
Pallet Component Pushing
Pushes heavy cardboard components into a palletizing station, where the TC trunnion mount accommodates the slight angular misalignment during the push cycle.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X125SUTC the Right Cylinder?
When sizing this 32 mm bore, compare it directly against its neighbours: a 25 mm bore provides 245.3 N of push at 0.5 MPa, while stepping up to the 40 mm bore yields 628.3 N. Choose this model when your application requires that intermediate 402.2 N thrust. The TC trunnion mount pairs with the U 90-degree back cover to offer flexible pivot installation options.
Remember that the fixed TPU bumpers only decelerate the piston near the stroke end; they do not function as a brake. If air pressure drops or the valve is centred, the rod will drift and drop any suspended mass. To prevent vertical loads from falling, you must integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 MI32X125SUTC FAQ
This 32 mm bore cylinder features a 1/8" air port and a 12 mm rod. At 0.5 MPa it provides 402.2 N of push force and 345.6 N of pull force. 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 indicates a built-in piston magnet, allowing you to mount CMSG, DMSG, or EMSG electronic or reed switches directly to the body. This specific configuration includes a U 90-degree back cover for perpendicular port access and mounting versatility.
