About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X225CM
Generating 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles demanding actuation with a 225 mm stroke. The stainless-steel barrel and piston rod supply mild corrosion resistance, making it highly suitable for damp production lines or washdown environments where painted steel units degrade. Riveted construction keeps the assembly compact, while fixed TPU bumper pads absorb impact energy at the stroke ends to protect internal components.
Air enters via a 1/8 inch port to drive the Ø12 mm rod, yielding a theoretical maximum output of 82 kgf at 1.0 MPa. For practical sizing at 0.5 MPa, plan for a safe working load of roughly 241 N rather than the absolute rating. This translates to lifting about 20.5 kg vertically with a 2:1 safety margin, allowing you to match the actuator precisely to real part weights. The CM round end back cover provides a clean rear profile for straightforward mounting integration.

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 MI32X225CM Is Used
Package Diverting Gate
Actuates a heavy routing flap on a logistics conveyor, relying on the 402.2 N push force at 0.5 MPa to redirect dense cartons reliably.
Parts Press Insertion
Pushes bearings into housings on an assembly line, using the 225 mm stroke to reach deep into fixtures while the TPU bumpers absorb the end impact.
Pallet Stopper Arm
Extends a blocking lever to halt loaded pallets on a roller track, with the stainless build surviving occasional washdowns in food distribution hubs.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X225CM the Right Cylinder?
Sizing this 32 mm bore requires looking both directions: stepping down to the 25 mm bore drops the 0.5 MPa push force to 245.3 N, while moving up to the 40 mm bore increases it significantly to 628.3 N. Because this 225 mm stroke is relatively long, carefully manage side loading to prevent rod bending and premature seal wear. Ensure your mounting choice—whether LB foot, FA flange, or TC trunnion—supports the extended rod properly.
This SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG position switches; choose an -S variant if you require electronic sensing. Furthermore, the fixed TPU bumpers only decelerate the piston near the stroke end—they do not function as an adjustable air cushion. A plain double-acting cylinder will drift and drop its load if air pressure is lost or the valve is centred; install an external rod lock or pilot-operated check valve if your application requires strict position holding.
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 MI32X225CM FAQ
This 32 mm bore cylinder features a 1/8 inch air port and a male M10x1.25 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 of 82 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet. You must select an -S variant to use CMSG, DMSG, or EMSG switches. Additionally, note that Ø32 is a non-ISO-6432 round-body size, and the fixed TPU bumpers only decelerate the stroke end rather than providing adjustable cushioning.
