About the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X20
Twin rods exit both covers of this stainless-steel round-body mini cylinder, yielding equal thrust in both directions while resisting rotation during fast moves. The MICD40X20 delivers 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa, with a 1/4 inch port and a robust M12x1.25 male rod thread.
Adjustable needle air cushions at both ends soak up end-of-stroke shock at speeds up to 800 mm/s. Because this SKU lacks the -S magnet, it cannot host CMSG or DMSG sensors; choose the -S variant if you need position detection.

| Stroke | 20 mm |
| 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 MICD40X20 Is Used
Short-Stroke Clamping
Uses the equal 738.9 N both-ways thrust to clamp parts securely on the extend and retract, with the 20 mm stroke minimizing cycle time.
High-Speed Diverting
Twin rods prevent twisting during rapid lane shifts, while the adjustable air cushions absorb the shock of sudden stops at 800 mm/s.
Compact Push-Off
Moves roughly 27 kg each way with a 2:1 vertical lift margin, leveraging the stainless build for mildly corrosive washdown environments.
Is the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X20 the Right Cylinder?
For lighter loads, the MICD32X75S bore provides 345.6 N at 0.5 MPa, while this 40 mm bore is the largest available in the series with no larger standard option. The double-rod and cushion combination is ideal for short 20 mm strokes requiring precise, shock-free reversal.
Note that the air cushion only decelerates near the stroke end and does not act as a brake; add an external rod lock or pilot check valve to hold a load on air loss. Mount via LB foot, FA flange, or TC trunnion, as the SDB pivot block is not offered on double-rod units.
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 MICD40X20 FAQ
The MICD40X20 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 inch port.
No, this specific SKU lacks a magnet and cannot host CMSG, DMSG, or EMSG sensors; you must select the -S variant for sensing. The adjustable air cushions at both ends only decelerate the piston near stroke end and do not lock or hold the load.
