About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X160R
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles substantial work within a compact footprint. The stainless-steel barrel and piston rod provide excellent mild corrosion and washdown resistance, outperforming painted alternatives in damp environments. Its 160 mm stroke and rear R axial-in port configuration make it highly practical for tight machinery layouts.
Because the bore is Ø32, this unit exceeds the ISO 6432 mounting dimensions, operating purely as a robust round-body actuator rather than a standard mini. It relies on fixed TPU bumper pads to decelerate the stroke end, rather than an adjustable air cushion. Plan for a safe working load of roughly 241 N, which lets you lift 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 MI32X160R Is Used
Package Diverting Gate
Shifts heavy cardboard cartons on a washdown packaging line, utilising the 402.2 N push force and stainless body to withstand damp cleaning environments.
Textile Loom Tensioning
Maintains precise fabric tension via the rear R axial-in port, driving a 160 mm stroke tensioning arm without requiring magnetic feedback.
Pallet Stopping Arm
Halts loaded pallets up to 20.5 kg on a gravity roller conveyor, relying on fixed TPU bumpers to absorb the repeated end-of-stroke impacts.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X160R the Right Cylinder?
When sizing this 160 mm stroke actuator, compare it against the adjacent bores: the Ø25 delivers 245.3 N of push at 0.5 MPa, while the Ø40 steps up to 628.3 N. If your application needs true adjustable air cushioning for high-speed cycles, step up to the MIC variable-cushion variant. Keep in mind that a plain cylinder drifts when air is lost or the valve is centred; the bumpers only soften the end of stroke, so add an external rod lock or pilot check valve if you need to hold a load.
This specific SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG or EMSG position switches. You can mount it using LB foot, FA flange, SDB pivot or TC trunnion brackets, alongside CA, U, R or CM back covers. For a 160 mm stroke, ensure your front mounting guides the load to prevent rod bending and premature seal wear.
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 MI32X160R FAQ
This double-acting cylinder uses a 1/8 inch air port. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, increasing to 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet, so it cannot accept CMSG, DMSG or EMSG switches. You would need the -S variant for sensing. Also, note that the Ø32 bore exceeds ISO 6432 dimensions, functioning purely as a round-body actuator with fixed TPU bumper pads.
