About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X225SU
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MI32X225SU is a robust double-acting round-body mini cylinder built for demanding automation. Its stainless-steel barrel and Ø12 mm piston rod shrug off mild corrosion, making it highly suitable for damp washdown environments where painted steel alternatives quickly degrade. The riveted construction remains compact while handling a 225 mm stroke, and fixed TPU bumper pads absorb impact energy at both stroke ends.
This bore size uses a 1/8 inch air port and an M10x1.25 male rod thread to support its higher force class. For practical 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. The U-style 90-degree rear cover provides flexible mounting orientation, and because this SKU includes the -S magnet, it is fully ready for CMSG, DMSG or EMSG position switches.

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 MI32X225SU Is Used
Package Diverting
Leveraging its 402.2 N push force to positively redirect heavy cartons on a 90-degree sorting conveyor line.
Clamp Actuation
Securing aluminium extrusion profiles during CNC machining operations using the 225 mm stroke to clear the work zone.
Pallet Positioning
Indexing loaded pallets into a stretch-wrap station where the stainless build resists ambient humidity and dust.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X225SU the Right Cylinder?
Sizing this 32 mm bore against its neighbours ensures the right fit: the smaller Ø25 generates 245.3 N of push at 0.5 MPa, while the larger Ø40 provides 628.3 N, so the MI32 sits comfortably in the mid-to-heavy force band. At a 225 mm stroke, keep the side-load minimal to prevent rod bending, as long strokes naturally amplify leverage on the front seal. The U back cover allows 90-degree pivot mounting, but remember that a plain double-acting cylinder drifts when air is removed or a valve is centred; the TPU bumpers only decelerate the stroke end and do not act as a lock. To suspend a load safely during an air loss event, fit 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 MI32X225SU FAQ
This 32 mm bore cylinder features a 1/8 inch air port and generates 402.2 N push / 345.6 N pull at 0.5 MPa, 563 N push / 483.8 N pull at 0.7 MPa, and a theoretical maximum of 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 function as a brake. You must use an external rod lock or pilot check valve to hold a load.
