About the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X75S
Twin rods exit both covers of this stainless round-body mini cylinder, yielding identical thrust in extend and retract while resisting rotation. As a double-acting actuator with a 40 mm bore and 75 mm stroke, it generates 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa each way. Needle-adjustable air cushions at both ends soak up high-speed end-of-stroke shock, making the unit ideal for guided, fast moves. The stainless barrel and rod resist mild corrosion and washdown environments.
With a 1/4" port and an M12x1.25 male rod thread, this variant includes a built-in piston magnet (-S) for CMSG, DMSG, or EMSG switches. Operating pressure spans 0.15 to 1.0 MPa. Based on the 0.5 MPa output, expect a safe working load around 317 N, or a vertical lift of about 26.9 kg with a 2:1 margin. Note that the cushion only decelerates the piston near stroke end; it does not lock or hold the load on air loss.

| Acting type | Double acting, double rod + cushion |
| 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 MICD40X75S Is Used
Package Diverting
Handles 26.9 kg cartons at speed on a sorting line, using the twin rods to resist twist during lateral pushes while cushions absorb end impact.
Press Ejection
Ejects stamped parts with 317 N of safe working force, relying on equal thrust both ways to retract the part cleanly without shock damage.
Guided Stopping
Acts as a high-speed stopper for pallets, where the through-rod backs a hard stop and the adjustable cushion decelerates the load smoothly.
Is the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X75S the Right Cylinder?
For tasks needing less push, the smaller MICD32 bore provides 345.6 N at 0.5 MPa, while this 40 mm bore is the largest available in the series with no larger option. Choose this double-rod configuration with adjustable cushions when a fast, guided, shock-sensitive move is required. Mount using LB foot, FA flange, or TC trunnion brackets, as the SDB pivot block is not offered on double-rod variants. The -S magnet enables position sensing with CMSG, DMSG, or EMSG switches. To prevent drift on air loss, install an external rod lock or pilot check valve.
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 MICD40X75S FAQ
It provides equal force both ways at 527.8 N @0.5 MPa and 738.9 N @0.7 MPa, with a theoretical maximum of 107.6 kgf. The air port is 1/4".
No, the piston will drift on air loss. The adjustable air cushion only decelerates the piston near stroke end and acts as neither a lock nor a brake. Use an external rod lock for holding.
