About the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X200
Engineered for heavy-duty guided motion, this round-body stainless steel mini cylinder uses a through-rod design that exits both covers. Because the piston sees the rod-side area on each face, the MICD40X200 generates an equal 527.8 N of thrust at 0.5 MPa in both directions. The adjustable air cushion at each end soaks up end-of-stroke shock, allowing safe operation at speeds up to 800 mm/s without slamming the covers.
The stainless steel barrel and rod resist mild corrosion and washdown environments. Featuring a 40 mm bore, a 200 mm stroke, and a 1/4" port, this riveted construction unit provides a safe working load of roughly 317 N, or a vertical lift of about 26.9 kg with a 2:1 margin. Note that this base SKU lacks a magnet and cannot host position sensors; adding the -S option enables CMSG, DMSG, or EMSG switches.

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 MICD40X200 Is Used
Pallet Diverter Gate
Uses the equal 527.8 N force both ways to push heavy pallets smoothly onto a side lane, while the twin rod prevents twist during the 200 mm transfer.
Carton Flap Folder
Closes heavy corrugated flaps at high speed; the adjustable air cushions absorb the end-of-stroke impact to protect the packaging mechanics.
Vertical Lift Stopper
Acts as a 200 mm stroke stop gate for totes, relying on the stainless build for damp warehouse settings and the twin rods to halt rotation.
Is the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X200 the Right Cylinder?
When sizing this 40 mm bore unit, consider stepping down to the MICD32, which yields 345.6 N at 0.5 MPa for lighter loads, as there is no larger standard bore in this mini cylinder family. The double-rod layout is optimal when you need equal force both ways and resistance to rotation, while the needle-set air cushions are essential for fast, shock-sensitive moves. Mounting options include LB foot, FA flange, and TC trunnion, plus CA, U, R, or CM back covers, but the SDB pivot block is not offered on this double-rod variant.
Remember that the air cushion only decelerates the piston near the stroke end; it does not function as a lock or brake. If your application must hold a vertical load during air loss, install an external rod lock or a pilot-operated check valve, because the piston will drift otherwise.
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 MICD40X200 FAQ
The double-rod design provides equal force both ways: 527.8 N at 0.5 MPa, 738.9 N at 0.7 MPa, and a maximum theoretical output of 107.6 kgf at 1.0 MPa. It uses a 1/4" port and a 16 mm rod.
No, this specific SKU lacks a magnet and cannot take a sensor. You must select the -S variant to use CMSG, DMSG, or EMSG switches. The adjustable air cushions at both ends only decelerate the load and do not lock or hold position on air loss.
