About the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X25
Built as a round-body stainless-steel mini cylinder, the MICD40X25 uses a double-acting through-rod to deliver 527.8 N of thrust at 0.5 MPa in both directions. The twin-rod architecture resists rotation and allows the rear rod to trip external stops, while adjustable air cushions at both covers soak up high-speed end-of-stroke shock. Its stainless barrel and piston rod withstand mild washdown environments.
Featuring a 40 mm bore and a 25 mm stroke, this unit pushes a safe working load of roughly 317 N. It moves about 26.9 kg vertically each way with a 2:1 safety margin. The 1/4" port feeds the air supply, and because this SKU lacks the -S magnet, 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 | Force (both ways) |
|---|---|
| 0.5 MPa | 528 N |
| 0.7 MPa | 739 N |
| Max (@1.0 MPa) | 108 kgf |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).

Where the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X25 Is Used
Product Diverting
Equal 527.8 N force extends and retracts a diverting blade on a packaging line, while the twin rod prevents twist during fast 30-800 mm/s strokes.
Short-Stroke Clamping
Holds a 317 N safe working load against a machining fixture. The adjustable air cushion gently decelerates the 25 mm stroke to protect part finishes.
Vertical Lift Stop
Lifts a 26.9 kg payload with a 2:1 margin. The through-rod design allows the rear extension to actuate a secondary mechanical stop simultaneously.
Is the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X25 the Right Cylinder?
When sizing both ways, stepping down to the MICD32 yields 345.6 N at 0.5 MPa, while no larger MICD bore exists above 40 mm. Choose this double-rod plus cushion combination when you need equal force both ways and shock absorption for rapid 30-800 mm/s cycling. Note that the air cushion only decelerates the piston near stroke end; it does not lock the load. Use an external rod lock or pilot check valve to prevent drift on air loss.
Mounting options include LB foot, FA flange and TC trunnion brackets, as well as CA, U, R and CM back covers. The SDB pivot block is not offered on this double-rod variant. If your application requires position sensing, select the -S magnet version to enable CMSG, DMSG or EMSG 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 MICD Air Cushion Double Rod Mini Cylinder MICD40X25 FAQ
The MICD40X25 provides equal force both ways: 527.8 N at 0.5 MPa, 738.9 N at 0.7 MPa, and a maximum theoretical force of 107.6 kgf at 1.0 MPa. It uses a 1/4" air port.
The adjustable air cushion only decelerates the piston near the stroke end; it is not a brake, so the load drifts on air loss. Use an external rod lock for holding. Also, this SKU lacks a magnet, so it cannot take CMSG, DMSG or EMSG sensors without the -S option.
