About the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X40S
Twin rods exit both covers of this stainless round-body mini cylinder, yielding equal 527.8 N force in both directions at 0.5 MPa while naturally resisting rotation. A needle-adjustable air cushion at each end soaks up end-of-stroke shock, making the build ideal for fast, guided moves. The stainless barrel and M12x1.25 rod resist mild corrosion and washdown.
Featuring a 1/4" port and a built-in magnet, this double-acting actuator supports CMSG, DMSG and EMSG sensors for mid-stroke positioning. Derived from the 0.5 MPa rating, expect a safe working load of about 317 N, which translates to lifting roughly 26.9 kg vertically with a 2:1 safety margin.

| Port size | 1/4" |
| Rod thread | M12×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |

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 MICD40X40S Is Used
Carton Diverting
Equal 527.8 N force both ways lets a twin-rod arm push and retract diverters at high speed, while the adjustable cushion absorbs the shock of stopping the 40 mm stroke.
Filler Head Lift
The stainless build handles washdown, and the twin rods keep the lifting platform from twisting as it moves roughly 26.9 kg of filling equipment vertically.
Parts Ejection
A back rod trips a CMSG sensor to confirm ejection while the front rod pushes parts out, with the needle cushion gently slowing the rapid 527.8 N strike.
Is the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X40S the Right Cylinder?
If 527.8 N is excessive, step down to the MICD32 bore providing 345.6 N at 0.5 MPa; as the largest in the series, no larger standard AirTAC round-body mini exists above Ø40. Choose this double-rod plus cushion combination when a fast 40 mm stroke demands precise anti-rotation guidance and gentle end-of-stroke deceleration.
Mount using LB foot, FA flange or TC trunnion brackets, noting the SDB pivot block is not offered on this twin-rod variant. Because the air cushion only decelerates and does not brake, add an external rod lock or pilot check valve if the load must hold position on air loss.
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 MICD40X40S FAQ
Because a rod exits both ends, force is equal both ways: 527.8 N at 0.5 MPa, 738.9 N at 0.7 MPa, and a maximum theoretical 107.6 kgf at 1.0 MPa. It uses a 1/4" port.
No, the adjustable air cushion only decelerates the piston near the stroke end; it is not a lock or brake. The piston will drift on air loss, so use an external rod lock for holding. The -S magnet enables position sensing.
