About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X110U
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavier automation tasks. The stainless-steel barrel and Ø12 mm rod shrug off mild corrosion and washdown environments better than painted alternatives. A 1/8" port supplies air, while fixed TPU bumper pads absorb stroke-end impact.
Because the 402.2 N rating is theoretical, plan for a safe working load of roughly 241 N. That translates to lifting about 20.5 kg vertically with a 2:1 safety margin. The U back cover provides a 90-degree port orientation for tight machinery layouts. This SKU lacks a magnet, so it cannot accept CMSG, DMSG or EMSG sensors without upgrading to the -S variant.

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 MI32X110U Is Used
Package Diverting
Pushes heavy cartons off a main conveyor line using its 241 N safe working load to overcome box friction.
Clamp Actuation
Secures metal workpieces in a CNC milling fixture, utilising the 90-degree U cover to keep ports out of the work zone.
Pallet Stopper
Halts incoming pallets on a roller bed, where the fixed TPU bumpers absorb the 110 mm stroke impact repeatedly.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X110U the Right Cylinder?
When sizing this 32 mm bore, compare it against its neighbours: a 25 mm bore gives 245.3 N of push at 0.5 MPa, while a 40 mm bore yields 628.3 N. Choose this model when your application sits comfortably above 245 N but below 628 N. Remember that a plain cylinder drifts when air is lost or the valve is centred; the TPU bumpers only decelerate the stroke end and act as neither a lock nor a brake. For suspended loads, install an external rod lock or pilot-operated check valve.
The 110 mm stroke is well within the 500 mm maximum standard stroke, keeping the unit as a readily available stock item. With no -S suffix, this specific SKU cannot host position sensors. If your sequencing requires detection, select the magnet-equipped version to enable CMSG, DMSG or EMSG switches.
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 MI32X110U FAQ
This 32 mm bore cylinder features a 1/8" port and a M10x1.25 male rod thread. 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.
No, this specific SKU lacks the internal magnet required for switches. To use CMSG, DMSG or EMSG sensors, you must purchase the -S variant. The unit also features a riveted stainless round body and fixed TPU bumpers, not an adjustable air cushion.
