About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X750SU
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles substantial work. The 32 mm bore operates on a 1/4" port, while the 750 mm stroke is a non-standard, made-to-order length exceeding the usual 500 mm maximum. Its stainless-steel barrel and piston rod resist mild corrosion, making it superior to painted alternatives in damp environments. The riveted construction keeps the body compact despite the extended reach.
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, this translates to hoisting around 20.5 kg with a 2:1 safety margin. The U-style back cover provides a 90-degree port orientation for tight routing. Fixed TPU bumper pads decelerate the piston at the stroke ends, though they do not act as an adjustable air cushion.

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 MI32X750SU Is Used
Long-Reach Diversion
Pushes heavy packages across a wide sorting conveyor belt using the full 750 mm stroke and 402.2 N force.
Textile Beam Shift
Transfers large fabric beams between processing stations in a textile mill, utilizing the 20.5 kg vertical lift capacity.
Pallet Component Feed
Advances heavy metal brackets down an assembly line, relying on the stainless build to endure humid factory conditions.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X750SU the Right Cylinder?
When sizing this actuator, consider the neighboring bores: a 25 mm version provides 245.3 N of push at 0.5 MPa, while a 40 mm bore offers 628.3 N. Because the 750 mm stroke greatly exceeds the 500 mm standard limit, carefully evaluate side loads to prevent rod bending over that extended length. If your application requires position holding, note that a standard cylinder drifts when air is lost; you must integrate an external rod lock or pilot check valve. This SKU includes a built-in magnet for CMSG, DMSG, or EMSG sensors.
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 MI32X750SU FAQ
This 32 mm bore cylinder features a 1/4" 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.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper pads only decelerate the stroke end and do not function as a brake. For vertical loads, install an external rod lock or pilot-operated check valve.
