About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X15CM
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles substantial work in tight spaces. The stainless-steel barrel and Ø12 mm rod shrug off mild corrosion, making it highly suitable for damp washdown environments where painted steel degrades. Its compact 15 mm stroke is governed by fixed TPU bumper pads that absorb end-of-travel impacts without requiring manual adjustment. Equipped with a 1/8" port and a CM round rear cover, it moves a high volume of air rapidly to achieve swift actuation.
When sizing this actuator for real-world tasks, plan for a safe working load of roughly 241 N, which accounts for friction and ensures reliable operation at 0.5 MPa. In vertical lifting scenarios, this translates to hoisting approximately 20.5 kg safely with a 2:1 margin. Because this specific SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG position switches; sensing requires ordering the magnet-equipped variant instead.

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 MI32X15CM Is Used
Stamping Pin Ejection
Provides the 402.2 N push force required to eject heavy stamped metal pins from a die in a compact fabrication cell.
Pallet Diverter Arm
Actuates a heavy-duty diverter arm on a packaging conveyor, using its 15 mm stroke to reroute dense product flow rapidly.
Process Valve Actuation
Drives a robust process valve in a washdown zone, leveraging the stainless-steel construction to resist moisture and cleaning chemicals.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X15CM the Right Cylinder?
If your application requires less force, stepping down to the Ø25 bore yields 245.3 N of push at 0.5 MPa, whereas moving up to the Ø40 bore provides 628.3 N. The Ø32 sits in a robust middle ground for heavy mini-cylinder tasks. Keep in mind that a plain double-acting cylinder drifts when air pressure is lost or the valve is centered; the TPU bumpers only decelerate the stroke end and will not lock the load. To maintain vertical position holding, integrate an external rod lock or a pilot-operated check valve. For high-speed cycles generating significant kinetic energy, consider the MIC variant, which offers adjustable air cushioning.
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 MI32X15CM FAQ
At 0.5 MPa it provides 402.2 N push and 345.6 N pull. At 0.7 MPa it delivers 563 N push and 483.8 N pull. The theoretical maximum force is 82 kgf at 1.0 MPa. The air port size is 1/8".
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You must select the -S magnet variant for position sensing. It features a CM round rear cover and fixed TPU bumper pads for end-of-stroke deceleration.
