About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X225R
Delivering 402.2 N of push force at 0.5 MPa, this AirTAC MI32X225R is a robust double-acting round-body mini cylinder built for demanding automation. The stainless-steel barrel and Ø12 mm piston rod shrug off mild corrosion and washdown environments, outlasting painted alternatives in damp facilities. A 1/4" port supplies air to drive the 225 mm stroke, while fixed TPU bumper pads absorb the impact at each stroke end. The rear R cover features an axial-in port orientation for tight inline plumbing.
For real-world sizing, plan for a safe working load of roughly 241 N rather than the absolute maximum rating. That translates to lifting about 20.5 kg vertically with a 2:1 safety margin, letting you match the cylinder to actual component weights. Note this specific SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors without switching to an -S variant.

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 MI32X225R Is Used
Package Diverting Gate
Actuates a heavy routing flap on a logistics conveyor, using the 402.2 N push force to reliably redirect parcels weighing up to 20 kg onto secondary sorting belts.
Carton Flap Folding
Drives a mechanical arm to fold corrugated carton flaps prior to sealing, where the 225 mm stroke provides the extended reach needed to clear tall packaging formats.
Parts Ejection Press
Pushes stamped metal components out of a hydraulic press bed, benefiting from the stainless construction to resist cutting fluid mist and shop floor humidity.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X225R the Right Cylinder?
When sizing this 32 mm bore, stepping down to a 25 mm cylinder drops the 0.5 MPa push force to 245.3 N, whereas stepping up to a 40 mm bore yields 628.3 N. The 225 mm stroke is well within the 500 mm maximum standard stroke, keeping the unit readily available. Because the rod extends 225 mm, ensure your mounting arrangement—whether LB foot, FA flange, SDB pivot or TC trunnion—prevents excessive side loading that could bend the rod. This R-cover version uses a rear axial port, so plan your manifold layout accordingly.
A standard double-acting cylinder drifts when air pressure is lost or the directional valve is centred; the TPU bumpers only soften the end-of-stroke impact and will not lock the piston in place. If your mechanism must hold a vertical load securely during an emergency stop or pressure drop, install an external rod lock or a pilot-operated check valve in the air line.
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 MI32X225R FAQ
This 32 mm 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, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum force of 82 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG or EMSG reed switches. You would need the -S variant (MI32X225R-S) to enable magnetic sensing. It uses fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable air cushion.
