About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X30CM
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 piston rod shrug off mild corrosion, making it superior to painted alternatives in damp washdown areas. It features a 1/8 inch air port, an M10x1.25 male rod thread, and a CM round end cover. Fixed TPU bumper pads absorb impact at the stroke extremes, operating smoothly across a 30-800 mm/s speed range.
For practical sizing, plan for roughly 241 N of real work at 0.5 MPa, which translates to lifting about 20.5 kg vertically with a safe 2:1 margin. This SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG position switches. If your sequence requires electronic feedback, you must select the -S 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 MI32X30CM Is Used
Stamping Pin Ejection
Uses the 402.2 N push force to knock stamped metal pins out of a die block quickly in automated fabrication lines.
Package Divert Arm
Actuates a short 30 mm swing arm to reroute heavy cardboard cartons on a packaging conveyor without overshooting.
Pallet Stop Gate
Deploys a solid mechanical stop to halt loaded pallets at a weighing station, relying on the stainless build for dusty environments.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X30CM the Right Cylinder?
When sizing this 32 mm bore, compare it against its neighbours: a 25 mm bore yields 245.3 N of push at 0.5 MPa, while stepping up to a 40 mm bore provides 628.3 N. The 30 mm stroke is very short, minimizing rod-bending side-load risks. Because the base MI relies on fixed TPU bumpers rather than an adjustable air cushion, avoid using it for high-speed heavy loads—the MIC variant is built for that. Note that this plain cylinder drifts when air is lost or a valve is centered; the bumpers only decelerate the end of stroke and will not lock the load. To hold a vertical position securely, add an external rod lock or a pilot-operated check valve.
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 MI32X30CM FAQ
At 0.5 MPa it provides 402.2 N push and 345.6 N pull. At 0.7 MPa it provides 563 N push and 483.8 N pull. The theoretical maximum force is 82 kgf at 1.0 MPa. The air port is 1/8 inch and the male rod thread is M10x1.25.
No, this specific SKU does not have a magnet. You must purchase the -S version of the MI series to use CMSG, DMSG, or EMSG switches. Additionally, this 32 mm bore is a non-ISO-6432 round-body mini cylinder, so verify your mounting bracket dimensions.
