About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X30R
Generating 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavy-duty actuation in tight spaces. The stainless-steel barrel and piston rod resist mild corrosion, making it superior to painted alternatives in damp or washdown environments. It features a 1/8" port and a male M10x1.25 rod thread. Fixed TPU bumper pads absorb stroke-end impact, and the compact 30 mm stroke is ideal for short, powerful movements.
Because this is a non-magnetic SKU, it cannot accept position sensors; you would need the -S variant for CMSG, DMSG or EMSG switches. For sizing, plan for a safe working load of about 241 N, which is roughly 60 percent of the 0.5 MPa push rating. Alternatively, it lifts about 20.5 kg vertically when applying 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 MI32X30R Is Used
Stamping Press Ejection
Uses the 402.2 N push force at 0.5 MPa to knock stamped metal parts out of a die quickly within the short 30 mm travel distance.
Heavy Package Diversion
Pushes heavier cartons on a packaging line where the stainless steel construction survives daily washdowns and damp factory conditions.
Clamp Actuation
Secures wooden or composite workpieces in a CNC fixture, taking advantage of the compact 30 mm stroke and the 1/8" port for rapid clamping.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X30R the Right Cylinder?
If you need less force, the Ø25 bore provides 245.3 N of push at 0.5 MPa, while stepping up to the Ø40 bore yields 628.3 N for heavier demands. This Ø32 model strikes a strong balance for mid-range tasks. Note that a plain cylinder drifts when air is lost or the valve is centered, as the TPU bumpers only decelerate the stroke end rather than locking the load. For secure holding, install an external rod lock or a pilot-operated check valve.
The R back cover configures the air supply with an axial-in port at the rear, simplifying plumbing in inline setups. Without the -S magnet option, this specific SKU cannot support magnetic sensing. Furthermore, while the 30 mm stroke is short and highly resistant to rod bending, always ensure the load is aligned to prevent side-load wear on the piston.
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 MI32X30R 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 size is 1/8".
No, this specific SKU lacks the internal magnet, so it cannot accept CMSG, DMSG or EMSG switches. You must select the -S variant for position sensing. It is a round-body mini cylinder with fixed TPU bumper pads, not an adjustable air cushion.
