About the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X225
Twin rods exit both ends of this stainless round-body mini cylinder, yielding equal 527.8 N force in both directions at 0.5 MPa while naturally resisting rotation. An adjustable air cushion at each end soaks up end-of-stroke shock during fast 225 mm moves. The stainless barrel and rod resist mild corrosion and washdown, and the 1/4 inch port feeds the Ø16 mm piston rod.
Because a rod occupies each side, thrust is identical extending and retracting. For vertical lifting, the 0.5 MPa output safely moves about 26.9 kg each way with a 2:1 margin. Note this base SKU lacks a magnet, so it cannot take CMSG, DMSG or EMSG sensors without specifying the -S option.

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 MICD40X225 Is Used
Carton Transfer Pusher
Pushes heavy cartons across a belt at 800 mm/s using equal 527.8 N force both ways, while the twin rods prevent twist and the cushions absorb the stop shock.
Vertical Lift Gate
Lifts a 26 kg material gate through 225 mm of travel, relying on the balanced double-rod thrust and adjustable air cushions to prevent slamming at the top.
Heavy Flap Folder
Folds thick packaging flaps rapidly without bounce, using the non-rotating twin rods and end cushions to decelerate the 527.8 N stroke smoothly.
Is the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X225 the Right Cylinder?
At 0.5 MPa this 40 mm bore yields 527.8 N both ways; stepping down to the MICD32 drops that to 345.6 N, while no larger MICD bore exists. Choose this double-rod plus adjustable cushion setup when you need guided, non-rotating motion with shock absorption at high speed. The cushion only decelerates near the stroke end and is not a lock, so add an external rod lock or pilot check valve to hold a load on air loss.
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 available on this double-rod variant. Remember that this specific SKU has no magnet, meaning position sensing is impossible unless you select the -S version.
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 MICD40X225 FAQ
Because a rod exits both ends, force is equal both ways. It provides 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.
No, this base SKU lacks a magnet and cannot accept CMSG, DMSG or EMSG sensors. You must specify the -S option for sensing. It features a 1/4 inch port, an M12x1.25 rod thread, and adjustable air cushions at both ends that decelerate the load but do not lock it.
