About the Airtac MIC Cushioned Mini Cylinder MIC40X25CM
Delivering 628.3 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavy duty cycles in tight spaces. The stainless-steel barrel and rod shrug off mild corrosion and washdown environments. A needle-set adjustable air cushion at both ends absorbs high-speed end-of-stroke shock, protecting your payload and cutting noise better than a fixed bumper.
With a 40 mm bore and 25 mm stroke, the CM round rear cover keeps the 1/4" port orientation clean for compact routing. It yields a safe working load of roughly 377 N, meaning it lifts about 32 kg vertically with a 2:1 safety margin. Note this SKU lacks the -S magnet, so it 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 MIC Cushioned Mini Cylinder MIC40X25CM Is Used
Heavy Clamp Press
Uses the 628.3 N push force to secure metal parts, while the adjustable cushion decelerates the 40 mm piston to prevent marking the workpiece.
Package Divert Arm
Swings heavy cartons at speed; the stainless build resists warehouse dust and the needle valve tunes the end stop to eliminate bang.
Vertical Flap Folder
Drives a 25 mm stroke to fold thick cardboard, lifting about 32 kg safely with the 2:1 margin while the CM cover eases rear mounting.
Is the Airtac MIC Cushioned Mini Cylinder MIC40X25CM the Right Cylinder?
If 628.3 N push at 0.5 MPa is too much, step down to the MIC32 bore which provides 402.2 N; there is no larger MIC bore above 40 mm. The adjustable cushion is essential when driving heavy loads at high speed, as it only decelerates the piston near the stroke end without acting as a brake. For vertical loads, remember the piston will drift on air loss—install an external rod lock or pilot check valve to hold position. Mount via LB foot, FA flange, SDB pivot, or TC trunnion.
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 MIC Cushioned Mini Cylinder MIC40X25CM FAQ
This 40 mm bore cylinder has a 1/4" port, a 16 mm rod with an M12x1.25 male thread, and a 25 mm stroke. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, or 879.6 N push and 738.9 N pull at 0.7 MPa. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for position sensing. The adjustable air cushion and stainless steel construction are present, but the cushion only decelerates the load and will not lock the rod in place.
