About the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X225S
Built with a stainless steel round barrel and twin rods exiting both covers, this Ø40 mm double-acting cylinder generates 527.8 N of thrust at 0.5 MPa and 738.9 N at 0.7 MPa. Because the piston rod occupies each side, the push and pull forces are perfectly equal. The integrated adjustable air cushions at both ends soak up high-speed end-of-stroke shock, while the 1/4" air port supplies ample flow for its 30-800 mm/s speed range.
The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG position switches. For sizing, a safe working load is roughly 317 N (about 60% of the 0.5 MPa figure), which translates to moving about 26.9 kg vertically each way with a 2:1 safety margin. Note that the cushion only decelerates the load near the stroke end; it does not function as a brake, so an external rod lock is required to hold position on air loss.

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 MICD40X225S Is Used
High-Speed Diverting
Equal 527.8 N thrust in both directions drives a diverting arm across a conveyor, while the twin rods resist torsional loads during rapid reversals.
Carton Pushing
The adjustable air cushions gently decelerate the 225 mm stroke when pushing heavy cartons, preventing harsh impacts that could damage packaging.
Vertical Lift Stop
Safely lifts or lowers a 26.9 kg fixture with a 2:1 margin, using the back rod to trip a CMSG sensor and confirm position in automated racks.
Is the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X225S the Right Cylinder?
If 527.8 N at 0.5 MPa is excessive, the smaller Ø32 mm MICD variant provides 345.6 N; conversely, there is no larger bore in this series, making this Ø40 mm model the maximum force option available. The double-rod layout is ideal when you need equal force both ways and resistance to rotation, while the needle-set air cushions are essential for fast, shock-sensitive moves over this 225 mm stroke.
Mounting options include LB foot, FA flange, and TC trunnion (the SDB pivot block is not offered on this double-rod variant). Position sensing is fully enabled by the factory-installed -S magnet, allowing direct fitment of CMSG, DMSG, or EMSG switches without further modification.
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 MICD40X225S FAQ
It features a 1/4" air port and delivers equal force both ways due to the double-rod design: 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, the adjustable air cushion only decelerates the piston near the end of stroke and does not act as a lock. You must use an external rod lock or pilot check valve to hold a load. The -S magnet enables CMSG/DMSG/EMSG sensors for position tracking.
