About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X40SCM
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavier automation tasks with ease. The stainless-steel barrel and Ø12 mm piston rod shrug off mild corrosion, making it highly reliable in damp or washdown environments compared to painted alternatives. It features a CM round rear cover and a 1/8" air port.
Equipped with a built-in magnet (-S), the unit supports CMSG, DMSG, and EMSG sensors for precise position detection. Fixed TPU bumper pads absorb end-of-stroke impacts without requiring adjustment. For practical sizing, plan for a safe working load of roughly 241 N, which means it can comfortably 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 MI32X40SCM Is Used
Package Diverting
Actuates heavy-duty routing gates on logistics conveyors, using its 402.2 N push force to reliably shift weighted cartons at high speeds.
Bottle Capping
Provides consistent downward pressure for securing caps on beverage lines, where the stainless construction survives daily washdown cycles.
Pallet Stops
Deploys a 40 mm stroke to halt pallets at loading zones, absorbing the impact via fixed TPU bumper pads without needing external shock absorbers.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X40SCM the Right Cylinder?
When sizing this 32 mm bore, stepping down to a 25 mm bore drops the 0.5 MPa push force to 245.3 N, while stepping up to a 40 mm bore increases it to 628.3 N. This 40 mm stroke keeps the rod compact, minimizing side-load bending risks. The CM round end cover offers specific rear mounting orientation. Because it includes the -S magnet, you can directly mount position switches.
Remember that the TPU bumpers only decelerate the piston near the stroke end; they do not function as a brake. If your application must hold a load vertically during air loss or valve centering, the piston will drift. You should integrate an external rod lock or a pilot-operated check valve to secure the payload safely.
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 MI32X40SCM FAQ
This 32 mm bore cylinder features a 1/8" air port and an M10x1.25 male rod thread. 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 force of 82 kgf at 1.0 MPa.
Yes, the -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG switches. However, it does not hold position on air loss; the piston drifts. You must add an external pilot check valve or rod lock for vertical load holding.
