About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X15SUTC
Delivering 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 and washdowns, outperforming painted alternatives in damp environments. It features a 1/4" air port and a compact 15 mm stroke. Equipped with a built-in magnet (-S), it supports CMSG, DMSG, and EMSG sensors for precise position detection.
For practical sizing, plan for a safe working load of about 241 N, which is roughly 60% of the 0.5 MPa push rating. This translates to lifting a 20.5 kg part vertically with a 2:1 safety margin. The riveted construction keeps the unit light, while fixed TPU bumper pads absorb stroke-end impacts. A U-type back cover provides 90-degree porting, and the included TC trunnion mount simplifies pivot installations.

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 MI32X15SUTC Is Used
Stamping Pin Ejection
Provides 402.2 N of push at 0.5 MPa to eject stamped metal pins from a die in automated press lines.
Heavy Package Diverter
Uses its 20.5 kg vertical lift capacity to divert heavy corrugated cartons on a logistics sorting conveyor.
Volumetric Fill Valve
Actuates a large-bore fluid valve for viscous food packaging, relying on the stainless rod for washdown resistance.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X15SUTC the Right Cylinder?
When sizing this 32 mm bore, compare it against adjacent options: the smaller Ø25 generates 245.3 N push at 0.5 MPa, while the larger Ø40 provides 628.3 N. Choose this model when your application requires that specific 402.2 N output. The 15 mm stroke minimizes rod bending risks, but always verify side-load alignment. This SKU includes the -S magnet for sensing and a TC trunnion for pivoting. Remember that a standard cylinder drifts if air pressure drops; the TPU bumpers only decelerate the stroke end and do not function as a lock. For suspended loads, install an external rod lock or pilot 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 MI32X15SUTC FAQ
This 32 mm bore cylinder features a 1/4" air port and a Ø12 mm rod. It delivers 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum of 82 kgf at 1.0 MPa.
No, the fixed TPU bumper pads only decelerate the piston near the stroke end; they do not act as a brake. If air is lost, the piston drifts. For suspended loads, use an external rod lock or pilot-operated check valve.
