About the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X30S
Built as a round-body stainless steel mini cylinder, the MICD40X30S uses a double-acting through-rod to deliver identical thrust in both directions. Because a Ø16 mm rod exits both covers, the effective area is equal on extension and retraction, yielding 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa. The 1/4" port feeds air to drive the piston at 30-800 mm/s, while the M12x1.25 male rod thread provides a sturdy attachment point.
Adjustable air cushions at both ends soak up end-of-stroke shock during these fast 30 mm moves. The stainless barrel and rod resist mild corrosion and washdown environments. With the built-in -S magnet, you can track position using CMSG, DMSG or EMSG switches. For sizing, a safe working load is roughly 317 N (about 60% of the 0.5 MPa force), which translates to lifting around 26.9 kg vertically with a 2:1 safety margin.

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 MICD40X30S Is Used
High-Speed Diverter
Equal 527.8 N force both ways swiftly pushes heavy cartons off a belt, while the twin rods prevent twist and the adjustable cushions absorb the rapid 30 mm stroke impact.
Guided Vertical Lift
Lifts roughly 26.9 kg of raw materials up and down with consistent force, using the through-rod to keep the payload stable and cushions to soften the landing.
Stamping Ejector
Ejects formed metal parts from a press with 738.9 N at 0.7 MPa, relying on the stainless build for mild corrosion resistance and the double-rod for precise linear ejection.
Is the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X30S the Right Cylinder?
Choose this 40 mm bore when you need substantial equal-both-ways force that a smaller MICD32 (345.6 N at 0.5 MPa) cannot provide; note that 40 mm is the largest bore in this series, so for higher loads you must switch to a different cylinder family. The double-rod plus adjustable cushion combination is ideal when you need high-speed actuation without slamming, and the twin rods resist rotation for guided payloads.
Remember that the air cushion only decelerates the piston near the stroke end—it does not lock or hold the load. If air pressure drops, the piston will drift, so fit an external rod lock or pilot check valve for suspended loads. Mount using LB foot, FA flange or TC trunnion brackets (the SDB pivot block is not offered on this double-rod variant). The -S magnet is already included for switch mounting.
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 MICD40X30S FAQ
It generates 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa, with a maximum theoretical force of 107.6 kgf at 1.0 MPa. Because it is a double-rod cylinder, this force is identical in both directions. The air port is 1/4".
No, the adjustable air cushions only decelerate the piston at stroke end; they do not act as a brake or lock, so the piston will drift if air is lost. The -S magnet is built-in, allowing you to mount CMSG, DMSG or EMSG switches for position sensing.
