About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X150SCM
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavier automation tasks with ease. The stainless-steel barrel and piston rod resist mild corrosion, making it far superior to painted alternatives in damp processing areas. It features a 1/8" port and a CM round rear cover for straightforward integration. Fixed TPU bumper pads absorb stroke-end impacts, and the built-in magnet (-S) supports CMSG, DMSG and EMSG sensors for position feedback.
For practical sizing, plan for a safe working load of roughly 241 N rather than pushing the absolute maximum. This translates to lifting about 20.5 kg vertically with a sensible 2:1 safety margin. Operating between 0.15 and 1.0 MPa, the riveted construction remains compact while generating substantial thrust for demanding machinery.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X150SCM Is Used
Package Diverting Gate
Actuates a heavy routing flap on a logistics conveyor, using the 402.2 N thrust to push dense parcels onto secondary sorting lanes without hesitation.
Carton Flap Folding
Drives the mechanical folder arms on a corrugated box sealing line, where the stainless build withstands fibrous dust and occasional washdowns.
Press Ejection Station
Ejects formed metal blanks from a stamping die, relying on the 150 mm travel and fixed TPU bumpers to absorb the repetitive end-of-stroke impact.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X150SCM the Right Cylinder?
When sizing this 32 mm bore, compare it directly against its neighbours: the 25 mm class provides 245.3 N of push at 0.5 MPa, while stepping up to the 40 mm bore yields 628.3 N. Choose this model when your application requires that extra mid-range thrust. The 150 mm stroke is well within the 500 mm standard maximum, keeping the assembly stable. If your mechanism experiences side loads, ensure adequate guide rails to prevent rod bending over this travel distance.
Remember that air pressure alone does not secure the piston; if the valve is centred or air is lost, the rod will drift and the TPU bumpers only decelerate the end of stroke rather than acting as a brake. To suspend a load safely mid-travel, install an external rod lock or a pilot-operated check valve. The CM round end cover offers specific rear mounting orientation, and the integrated magnet allows seamless fitting of reed or electronic switches.
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 MI32X150SCM FAQ
This 32 mm bore cylinder features a 1/8" port and a Ø12 mm rod. 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 function as a brake. To maintain a vertical position, you must add an external rod lock or a pilot-operated check valve.
