About the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X200S
Twin guide rods exit both covers of this stainless round-body mini cylinder, yielding identical thrust in both directions while resisting rotation during fast moves. The MICD40X200S generates 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa, using a 1/4 inch port and a 16 mm piston rod with an M12x1.25 male thread. Needle-adjustable air cushions at each end soak up end-of-stroke shock across the 200 mm travel at speeds of 30-800 mm/s.
The stainless steel barrel and rod construction resists mild corrosion and washdown environments. Because the rod occupies both faces, the effective area is identical on extension and retraction. With a 0.5 MPa supply, the safe working load is roughly 317 N, which moves about 26.9 kg vertically each way with a 2:1 safety margin. The built-in magnet (-S) supports CMSG, DMSG and EMSG position 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 MICD40X200S Is Used
Dual-Stop Conveyor Diverter
Uses the twin rods to push and retract packages with equal 527.8 N force, while the cushions absorb shock from rapid 200 mm strokes.
Vertical Film Roll Lift
Raises and lowers a 26 kg roll smoothly with a 2:1 margin at 0.5 MPa, relying on the through-rod to prevent load twisting.
Guided Stamping Press
Drives a light stamping tool at high speed, using the adjustable end cushions to prevent impact damage at the 200 mm travel limits.
Is the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X200S the Right Cylinder?
When sizing this 40 mm bore, dropping down to the MICD32 provides 345.6 N at 0.5 MPa if your load is lighter, while no larger bore exists in this series for heavier demands. The through-rod and adjustable cushion combination is ideal for fast, guided, shock-sensitive moves, and the 200 mm stroke sits well within the 500 mm maximum standard. Choose LB foot, FA flange or TC trunnion mounts, as the SDB pivot block is not offered on double-rod variants.
Remember that the air cushion only decelerates the piston near the stroke end; it does not function as a lock or brake. If air pressure drops, the piston will drift. For applications requiring a held load on air loss, install an external rod lock or a pilot-operated check valve.
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 MICD40X200S FAQ
It delivers equal force both ways because a rod exits both ends: 527.8 N at 0.5 MPa, 738.9 N at 0.7 MPa, and a maximum theoretical 107.6 kgf at 1.0 MPa. The air port size is 1/4 inch.
No, the piston will drift on air loss. The adjustable air cushions only decelerate the piston near the stroke ends to reduce shock; they do not act as a brake. Use an external rod lock or pilot check valve to hold a load.
