About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X50CM
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MI32X50CM is a robust double-acting round-body mini cylinder built for demanding compact automation. Its stainless-steel barrel and Ø12 mm piston rod shrug off mild corrosion, making it highly suitable for damp production environments where painted steel bodies would degrade. The riveted construction keeps the unit compact, while fixed TPU bumper pads absorb impact energy at the stroke ends to protect internal components.
Featuring a 1/8" port and a CM round end rear cover, this 32 mm bore model generates substantial power without needing a large footprint. For practical actuation tasks, plan for a safe working load of roughly 241 N, which is about 60 percent of the 0.5 MPa rating. Alternatively, it can vertically lift around 20.5 kg with a 2:1 safety margin, letting you directly match the cylinder to real part weights. Note that because this specific SKU lacks the -S suffix, it cannot accept CMSG, DMSG or EMSG magnetic sensors.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X50CM Is Used
Stamping Pin Ejection
Provides the 402.2 N of push force needed to eject small metal pins from a stamping die, utilizing its compact 50 mm stroke for fast cycling.
Heavy Package Diversion
Actuates a heavy-duty diverter arm on a packaging conveyor, where the stainless build resists washdown moisture and the CM round end simplifies rear mounting.
Pallet Stopper Gate
Functions as a robust stopper gate for loaded pallets, easily handling the 20.5 kg vertical lift equivalent to halt items securely on a roller track.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X50CM the Right Cylinder?
When sizing this 32 mm bore actuator, compare your actual load against its 402.2 N push and 345.6 N pull capabilities at 0.5 MPa. If your application requires less force, the smaller Ø25 bore offers 245.3 N of push, whereas stepping up to the Ø40 bore provides 628.3 N for heavier mechanisms. The 50 mm stroke is well within the 500 mm maximum standard limit, keeping the rod highly rigid and minimizing side-load bending risks.
Because this is a base MI variant with a CM round end and no -S magnet, position detection is not possible out of the box. Furthermore, the fixed TPU bumpers only decelerate the piston near the stroke end; they do not function as a brake. If your machinery requires the load to be held statically upon air loss or valve centering, you must integrate an external rod lock or a pilot-operated check valve, as the piston will drift otherwise.
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 MI32X50CM FAQ
This 32 mm bore cylinder features a 1/8" port and a Ø12 mm rod. At 0.5 MPa it generates 402.2 N of push force and 345.6 N of pull force. At 0.7 MPa, the push increases to 563 N and the pull to 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
This specific SKU does not have the -S suffix, meaning it lacks an internal piston magnet and cannot accept CMSG, DMSG, or EMSG switches. The CM designation indicates a round end rear cover, providing a straightforward threaded interface for direct rear mounting. It is a non-ISO-6432 round-body mini cylinder.
