About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X150SU
Generating a robust 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles substantial workloads within a compact footprint. The stainless-steel barrel and piston rod supply reliable mild corrosion resistance, outperforming painted alternatives in damp or washdown-prone environments. It features a 150 mm stroke and a 1/8" air port.
Equipped with a built-in piston magnet, the unit supports CMSG, DMSG and EMSG switches for precise position detection. Fixed TPU bumper pads absorb stroke-end impacts to protect the mechanism. For real-world sizing, plan for a safe working load of roughly 241 N, which translates to lifting about 20.5 kg vertically with a 2:1 safety 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 MI32X150SU Is Used
Package Diverting Gate
Actuates a heavy routing flap on a distribution conveyor, using its 402.2 N push force to reliably redirect 20 kg cartons at high speeds.
Parts Press Fixture
Drives a 150 mm downward clamping stroke on an assembly jig, securing aluminum housings prior to riveting or drilling operations.
Box Flap Folder
Deploys the 90-degree U-type rear cover and extended stroke to fold heavy corrugated cardboard flaps prior to case sealing.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X150SU the Right Cylinder?
When sizing this 32 mm bore, the smaller Ø25 MI generates 245.3 N of push at 0.5 MPa, while the larger Ø40 MI outputs 628.3 N, giving you clear scaling options if your air supply or payload shifts. The U-type back cover provides a 90-degree port orientation for tight routing. Because this is a 150 mm stroke, ensure your mounting arrangement—whether LB foot, FA flange, SDB pivot or TC trunnion—prevents rod side-loading and premature bending.
Remember that a standard double-acting cylinder drifts when air pressure is removed or the valve is centered; the TPU bumpers only decelerate the stroke end and do not function as a locking brake. To suspend a load safely during an outage, 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 MI32X150SU FAQ
This 32 mm bore cylinder features a 1/8" air port and generates 402.2 N push / 345.6 N pull at 0.5 MPa, and 563 N push / 483.8 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. To hold a vertical load, you must add an external rod lock or a pilot-operated check valve.
