About the Airtac MI25~40 Stainless Steel Mini Cylinder MI40X10SCM
Delivering a robust 628.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles the heaviest jobs in the MI family. The Ø40 bore operates on a 1/4" port with a 10 mm stroke, utilizing fixed TPU bumper pads to decelerate the piston at both ends without adjustable cushioning. Its riveted construction yields a compact footprint, while the stainless barrel and rod resist mild corrosion in damp or washdown environments.
Because the bore generates substantial thrust, plan for roughly 377 N of actual work at 0.5 MPa to maintain a safe margin. This translates to lifting about 32 kg vertically when applying a 2:1 safety factor. The built-in magnet (-S) supports CMSG, DMSG, and EMSG switches for position sensing, and the CM round end cover provides a clean rear profile for tight machine layouts.

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 Ø40 bore is a larger, non-ISO-6432 size.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
| Max (@1.0 MPa) | 128 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 MI40X10SCM Is Used
Heavy-Duty Stamping
Supplies the high impact force needed to seat or stamp solid metal components in automated press lines.
Pallet Diverter
Pushes heavy loaded pallets onto secondary packaging tracks using its 32 kg vertical-lift equivalent capacity.
Beef Processing Gate
Actuates heavy stainless-steel washdown gates in food plants, relying on the corrosion-resistant rod and barrel.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI40X10SCM the Right Cylinder?
As the largest available bore, the MI40 sits at the top of the range with no larger standard size; if 628.3 N at 0.5 MPa is excessive, step down to the Ø32 bore which provides 402.2 N of push force. The short 10 mm stroke minimizes rod-bending risks and side-load stress, making it ideal for high-force clamping rather than long reach. Remember that venting the air supply or centering the valve will cause the piston to drift, as the TPU bumpers only soften the end-of-stroke impact and do not function as a locking brake; incorporate a pilot-operated check valve if you must hold a load securely in place.
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 MI40X10SCM FAQ
This double-acting cylinder uses a 1/4" port and generates 628.3 N push / 527.8 N pull at 0.5 MPa, and 879.6 N push / 738.9 N pull at 0.7 MPa. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
Yes to the sensor: the -S suffix means it has a piston magnet ready for CMSG, DMSG, or EMSG switches. However, there is no adjustable air cushion; it relies solely on fixed TPU bumper pads to decelerate the stroke end.
