About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X50SCMTC
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles demanding actuation tasks. The stainless-steel barrel and piston rod provide excellent mild corrosion and washdown resistance, outperforming painted alternatives in damp environments. It features a 1/4" port, an M10x1.25 male rod thread, and fixed TPU bumper pads that decelerate the piston at stroke ends.
For practical sizing, plan for a safe working load of about 241 N rather than the absolute maximum. This translates to lifting roughly 20.5 kg vertically with a 2:1 safety margin. The built-in piston magnet supports CMSG, DMSG, and EMSG switches for position sensing, while the CM round rear cover and included TC trunnion mounting simplify installation.

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 MI32X50SCMTC Is Used
Package Diverting
Actuates routing gates on stainless-steel food-grade conveyor lines, using the 402.2 N thrust to push heavy cartons without corroding in washdown zones.
Clamp Actuation
Secures aluminum extrusions during CNC machining operations, where the 20.5 kg vertical lift capacity easily holds workpieces against cutting forces.
Pallet Stopper
Functions as a robust pneumatic stop on automated pallet handling systems, relying on the TC trunnion mount to absorb high lateral momentum.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X50SCMTC the Right Cylinder?
When sizing this 32 mm bore, compare it against adjacent options: a 25 mm bore yields 245.3 N of push at 0.5 MPa, whereas stepping up to a 40 mm bore provides 628.3 N. This model hits a strong middle ground for medium-force machinery. Because the stroke is a compact 50 mm, side-load and rod-bending stresses remain minimal even under rapid cycling.
Remember that the fixed TPU bumpers only soften end-of-stroke impacts; they do not function as a lock. If air pressure drops or the valve is centred, the piston will drift, so you must integrate an external rod lock or pilot-operated check valve to suspend a load safely.
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 MI32X50SCMTC FAQ
This 32 mm bore cylinder features a 1/4" 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 fixed TPU bumper pads only decelerate the piston near the stroke end and act as a brake. The piston will drift if air is lost or the valve is centred. An external rod lock or pilot check valve is required to hold a load securely.
