About the Airtac MI25~40 Stainless Steel Mini Cylinder MI40X10CM
Delivering 628.3 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavy-duty tasks in tight spaces. The stainless-steel barrel and rod shrug off mild corrosion, making it superior to painted alternatives in damp or washdown environments. With a 1/4 inch port and a 16 mm rod, it is built for robust operation.
For practical sizing, plan for about 377 N of real work at 0.5 MPa, which safely lifts roughly 32 kg vertically with a 2:1 margin. The 10 mm stroke and CM round end cover excel at short, powerful clamping. Fixed TPU bumper pads absorb the stroke-end impact, though this SKU lacks a magnet and cannot host CMSG, DMSG, or EMSG sensors.

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 MI40X10CM Is Used
Heavy-Duty Stamping
Provides intense 628.3 N impact force for marking or forming thick metal plates over a very short 10 mm travel distance.
Industrial Clamping
Secures heavy timber or steel workpieces on machining centers, using its robust 16 mm rod to resist deflection during aggressive milling.
Short-Stroke Ejection
Punches dense molded parts out of injection molds quickly, leveraging the high force output within a compact machinery footprint.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI40X10CM the Right Cylinder?
As the largest bore in the MI family, there is no larger standard size to step up to; if 628.3 N at 0.5 MPa is insufficient, you must explore external amplification. Stepping down to the Ø32 bore drops the push force to 402.2 N. Because this plain cylinder drifts when air is lost or a valve is centered, add an external rod lock or pilot check valve for suspended loads. The fixed TPU bumpers only decelerate the impact, so they never function as a braking lock.
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 MI40X10CM FAQ
This 40 mm bore cylinder features a 1/4 inch port and a 16 mm rod. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical maximum of 128.1 kgf at 1.0 MPa.
No, this specific SKU lacks a magnet and cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. It features a CM round end cover and fixed TPU bumper pads for stroke-end deceleration.
