About the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X15S
Twin extending rods and adjustable air cushions define this stainless-steel round-body mini cylinder, delivering 527.8 N of equal force in both directions at 0.5 MPa. The through-rod design resists rotation and allows the back rod to trip a stop or switch, while the needle valves soak up end-of-stroke shock during fast 30-800 mm/s cycles. Its 1/4" port feeds the 40 mm bore, which carries a 16 mm rod with an M12x1.25 male thread.
Because a rod exits both covers, the piston uses the pull-side area on each face, meaning thrust is identical whether extending or retracting (738.9 N at 0.7 MPa). The -S suffix adds a piston magnet for CMSG, DMSG or EMSG switches. For sizing, expect a safe working load of roughly 317 N, or a vertical lift of about 26.9 kg with a 2:1 margin. Note that the cushion only decelerates near the stroke end and does not lock the load 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 MICD40X15S Is Used
Short-Stroke Clamping
Ideal for locking heavy parts in a fixture using the 15 mm stroke, where the twin rods prevent rotation and the cushions absorb the sudden stop.
High-Speed Diverter
Pushes items across a belt with 527.8 N of equal thrust both ways, while the adjustable air cushions prevent end-of-stroke banging during rapid cycling.
Washdown Sealing Press
The stainless steel construction handles mild washdown as it presses cartons, using the back rod to trip a position switch without extra sensors.
Is the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X15S the Right Cylinder?
If 527.8 N at 0.5 MPa is excessive, the next size down is the 32 mm bore delivering 345.6 N; there is no larger standard MICD bore above 40 mm. This double-rod plus cushion combination is ideal when you need guided, fast, shock-sensitive moves within a 15 mm stroke. The stainless barrel and rod withstand mild washdown environments.
Mount using LB foot, FA flange or TC trunnion brackets, as the SDB pivot block is not offered on this double-rod variant. The included magnet supports CMSG, DMSG and EMSG sensors. Remember that the air cushion only decelerates the piston near the stroke end; to hold a load vertically on air loss, fit an external rod lock or pilot 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 MICD40X15S FAQ
Force is equal both ways because a rod exits each end: 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 40 mm bore uses a 1/4" air port and a 16 mm rod.
No, the piston will drift on air loss. The adjustable air cushions at both ends only decelerate the piston near the 15 mm stroke limits; they do not act as a brake. Use an external rod lock or pilot check valve for load holding.
