About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X75U
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MI32X75U is a double-acting round-body mini cylinder built for demanding medium-duty tasks. Its stainless-steel barrel and piston rod shrug off mild corrosion, making it highly suitable for damp washdown environments where painted steel or aluminium bodies degrade. The riveted construction keeps the unit compact, while fixed TPU bumper pads absorb impact energy at the stroke ends. This specific SKU features a 90-degree U back cover and uses a 1/8" port.
For practical sizing, plan for a safe working load of roughly 241 N, which is about 60 percent of the 0.5 MPa push rating. In vertical lifting scenarios, this translates to lifting a 20.5 kg mass with a 2:1 safety margin. Because this configuration lacks the -S suffix, it cannot accept CMSG, DMSG or EMSG magnetic switches. If position feedback is required, the -S magnet variant is necessary.

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 MI32X75U Is Used
Package Diverting Gate
Actuates a routing flap on a 600 mm wide packaging belt, using the 402.2 N thrust to push heavy cartons into a secondary lane at 30-800 mm/s.
Pallet Corner Aligner
Squares up loaded pallets on a roller conveyor, relying on the stainless build to survive ambient humidity and the 90-degree U cover for compact hose routing.
Press Pin Insertion
Drives a 12 mm diameter pin into an aluminium housing, applying a calculated 241 N of safe working force to seat the component without deforming the bore.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X75U the Right Cylinder?
When sizing this 32 mm bore, compare it against its neighbours: a 25 mm bore provides 245.3 N of push at 0.5 MPa, while stepping up to a 40 mm bore yields 628.3 N. The 75 mm stroke is well within the 500 mm maximum standard stroke, keeping the rod rigid and minimizing side-load bending risks. The U-style back cover orients the rear port 90 degrees to the body, which helps route hoses cleanly in tight machinery cabinets. Remember that a plain double-acting cylinder drifts when air pressure is lost or the valve is centred; the TPU bumpers only decelerate the end of stroke and do not function as a brake. To suspend a load safely during an air loss event, integrate an external rod lock or a pilot-operated check valve into your 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 MI32X75U FAQ
The 32 mm bore generates 402.2 N push and 345.6 N pull at 0.5 MPa, or 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa. Air is supplied via a 1/8" port, and the male rod thread is M10x1.25.
No, this specific SKU lacks the internal magnet, so CMSG, DMSG or EMSG switches cannot be used. You must select the -S variant for position sensing. Additionally, note this is a round-body mini cylinder rather than an ISO 6432 unit, and its fixed TPU bumpers only decelerate the stroke end rather than providing adjustable cushioning.
