About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X80SUG
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MI32X80SUG is a double-acting round-body mini cylinder built for robust automation. Its stainless-steel barrel and piston rod resist mild corrosion and washdowns, outperforming painted alternatives in damp environments. The riveted construction keeps the unit compact, while fixed TPU bumper pads absorb impact at the stroke ends.
This 32 mm bore, 80 mm stroke variant features a 1/8" G port and an M10x1.25 male rod thread. Because the bore exceeds the standard mini interface, it is classified simply as a round-body mini cylinder rather than ISO 6432. The built-in magnet (-S) supports CMSG, DMSG, and EMSG position switches. For real-world sizing, plan for a safe working load of roughly 241 N, which equates to lifting about 20.5 kg vertically with a 2:1 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 MI32X80SUG Is Used
Package Diverting
Pushes medium-weight cartons off a main conveyor belt using its 402.2 N thrust, surviving damp washdown zones thanks to the stainless steel construction.
Clamp Actuation
Secures aluminium extrusions during CNC machining operations, providing reliable clamping force without crushing the workpiece.
Pallet Stops
Acts as a heavy-duty pneumatic stop on roller conveyors to halt pallets weighing up to 20 kg during automated sorting processes.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X80SUG the Right Cylinder?
When sizing this 32 mm bore actuator, the neighbouring MI25 offers 245.3 N push at 0.5 MPa for lighter duties, while stepping up to the MI40 provides 628.3 N for heavier demands. The U-style back cover provides a 90-degree port orientation, easing plumbing in tight machinery. To track position, pair the internal magnet with CMSG or EMSG sensors.
Note that fixed TPU pads only decelerate the piston near the stroke end; they do not function as an adjustable air cushion. If air pressure drops or the valve centres, the piston will drift and cannot hold a load. For suspended loads, 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 MI32X80SUG FAQ
This 32 mm bore cylinder features a 1/8" G port and an M10x1.25 male rod thread. At 0.5 MPa it generates 402.2 N push and 345.6 N pull. At 0.7 MPa, push increases to 563 N and pull to 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, the piston will drift if air is lost or the valve is centred. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. For suspended or vertical loads, you must use an external rod lock or a pilot-operated check valve.
