About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X200SU
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MI32X200SU 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 degrade. The riveted construction keeps the unit compact while fixed TPU bumper pads absorb stroke-end impacts to protect your tooling.
Because this is a Ø32 bore, it steps outside the ISO 6432 standard dimensions, operating purely as a heavy-duty round-body mini cylinder. The built-in magnet (-S) directly supports CMSG, DMSG and EMSG switches for precise position detection, while the U back cover provides a 90-degree port and mounting orientation. For real-world tasks, 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 MI32X200SU Is Used
Package Diverting
Actuates heavy routing gates on logistics conveyors, using its 402.2 N thrust to push dense cartons reliably at high cycle rates.
Vertical Pressing
Provides steady downward clamping pressure for wood joining or light assembly jigs, lifting or pressing parts up to roughly 20.5 kg safely.
Textile Machinery
Shifts heavy guide rolls and tensioning arms in humid textile mills, leveraging the stainless steel body to resist fibrous dampness.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X200SU the Right Cylinder?
When sizing this 200 mm stroke model, compare its 402.2 N push force at 0.5 MPa against the neighbouring bores: a Ø25 generates 245.3 N, whereas a Ø40 steps up significantly to 628.3 N. The 1/4" port and M10x1.25 male rod thread are fixed by the Ø32 bore. Keep in mind that a plain double-acting cylinder drifts if air pressure drops or the valve centres; the TPU bumpers only decelerate the stroke end and will not lock the load. To hold a vertical position securely, fit an external rod lock or a pilot-operated check valve. Additionally, at 200 mm of extension, mind the side-load limits to avoid bending the rod.
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 MI32X200SU FAQ
This Ø32 bore cylinder features a 1/4" air port and an M10x1.25 male rod thread. 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, 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 install an external rod lock or a pilot-operated check valve.
