About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X50U
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles substantial work in a compact footprint. The stainless-steel barrel and piston rod supply mild corrosion resistance, proving highly effective in damp production zones or washdown environments. A 1/8" port feeds the 32 mm bore, while fixed TPU bumper pads absorb the impact at stroke extremes to protect your tooling.
Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches. For practical sizing, plan for a safe working load of roughly 241 N, which is about 60 percent of the 0.5 MPa rating. Alternatively, you can estimate it will lift a 20.5 kg mass vertically when applying a two-to-one safety margin.

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 MI32X50U Is Used
Package Diverting Gate
Actuates a heavy routing flap on a logistics conveyor belt, using its 402.2 N push force to reliably redirect dense cartons onto secondary sorting lanes.
Press Pin Insertion
Drives a 12 mm rod assembly to seat metal dowel pins into CNC-machined aluminium housings, relying on fixed TPU pads to soften the end-of-stroke impact.
Pallet Stopper Arm
Deploys a 50 mm stroke blocking arm at the end of a roller conveyor, securely halting loaded pallets weighing up to 20.5 kg in a vertical lift scenario.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X50U the Right Cylinder?
Sizing this 32 mm bore requires checking both neighbours: the 25 mm class yields 245.3 N of push at 0.5 MPa, whereas the larger 40 mm bore jumps to 628.3 N. Choose this model when the 25 mm falls short but you want to avoid the bulk of the 40 mm. Note that a plain cylinder drifts if air pressure drops or the valve centres; the TPU bumpers only decelerate the end of stroke and will not lock the load, so add an external rod lock or pilot check valve for vertical holding.
This variant features a U-style 90-degree rear cover for compact pivot mounting. The 50 mm stroke sits well within the 500 mm maximum standard stroke limit, keeping the Ø12 rod highly stable against side loads. If your machine requires adjustable end-cushioning for high-speed cycles, look at the MIC variant instead of the base MI.
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 MI32X50U FAQ
This 32 mm bore cylinder features a 1/8" air port and a 12 mm rod. At 0.5 MPa it provides 402.2 N of push and 345.6 N of pull. At 0.7 MPa the push is 563 N and pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet. You must select the -S variant to use CMSG, DMSG or EMSG switches. Additionally, this is a non-ISO-6432 round-body mini cylinder, so verify your mounting dimensions for the U-style 90-degree back cover.
