About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X280SU
Generating 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavy-duty positioning tasks. The stainless-steel barrel and rod resist mild corrosion, making it superior to painted alternatives in damp environments. It features a 1/8" port and a 90-degree U back cover for flexible routing. Fixed TPU bumper pads absorb the impact at stroke end, and the built-in magnet (-S) supports CMSG, DMSG, or EMSG sensors.
For practical sizing, plan for a safe working load of roughly 241 N rather than the absolute maximum. This translates to lifting about 20.5 kg vertically with a 2:1 safety margin. The 280 mm stroke is well within the 500 mm standard limit, providing extended reach without requiring a custom made-to-order part.

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 MI32X280SU Is Used
Pallet Diverter Gate
Actuates heavy routing gates on packaging lines, using its 402.2 N push force to reliably shift loaded pallets onto secondary conveyors.
Textile Loom Tensioner
Maintains consistent fabric tension during high-speed weaving, with the 280 mm stroke providing ample travel for the tensioning carriage.
Vertical Parts Elevator
Lifts automotive components weighing up to 20.5 kg between assembly tiers, relying on the stainless rod for durability in industrial environments.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X280SU 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. Choose this model when your application requires that extra mid-range thrust. Because the 280 mm stroke is quite long, ensure your mounting configuration prevents rod bending and side-load damage. The U back cover allows 90-degree port orientation, and the integrated magnet enables precise position sensing.
Remember that a standard cylinder drifts when air pressure drops or the valve is centered, as the TPU bumpers only decelerate the stroke end and act as neither a lock nor a brake. To suspend a load safely, install 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 MI32X280SU FAQ
This 32 mm bore cylinder features a 1/8" port and a 12 mm rod. It generates 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.
Yes, the -S suffix indicates a built-in piston magnet compatible with CMSG, DMSG, and EMSG switches. The U back cover provides a 90-degree port orientation, simplifying hose routing in tight machinery spaces.
