About the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X175
Twin rods exit both covers of this stainless round-body mini cylinder, yielding equal thrust in both directions while actively resisting rotation. The MICD40X175 pushes and pulls with 527.8 N at 0.5 MPa, guided by a Ø16 mm piston rod and M12x1.25 male threads. A needle-set variable air cushion at each end soaks up end-of-stroke shock for fast, shock-sensitive moves.
The stainless steel barrel and rod resist mild corrosion and washdown environments. Because the rod occupies both faces, the 1/4" port drives the pull-side area equally both ways. This non-magnet SKU cannot host a position switch; add the -S variant to enable CMSG, DMSG or EMSG sensors.

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 MICD40X175 Is Used
High-Speed Divertor Gate
Equal 527.8 N thrust both ways rapidly flips a divertor flap, while the twin rods resist torsional twist and the air cushions absorb the 175 mm stroke impact.
Heavy Carton Lid Press
Closes large cartons at speed; the adjustable cushions decelerate the platen smoothly at stroke end to prevent crushing, with the back rod free to trip an external stop.
Guided Package Stopper
Holds back heavy boxes on a gravity conveyor. The double-rod build resists side loads from skewed parcels, and the stainless body handles damp packing zones.
Is the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X175 the Right Cylinder?
Size both ways by comparing equal-both-ways thrust: the smaller Ø32 bore yields 345.6 N at 0.5 MPa, while the Ø40 here provides 527.8 N. There is no larger MICD bore, so for loads beyond this step up to an external profile format. The double-rod plus adjustable cushion combo fits fast, guided, shock-sensitive moves. Plan a safe working load around 317 N (60% of the 0.5 MPa force) or roughly 26.9 kg vertical lift with a 2:1 margin.
Mount using LB foot, FA flange or TC trunnion brackets, or CA, U, R and CM back covers; the SDB pivot block is not offered on this double-rod variant. The cushion only decelerates near stroke end and never acts as a lock, so fit an external rod lock or pilot check valve to hold a load on air loss. This SKU lacks a magnet, so it cannot take a sensor.
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 MICD40X175 FAQ
Because a rod exits both ends, force is equal both ways using the pull-side area. It generates 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 1/4" port drives this equal bidirectional thrust.
No. The adjustable air cushion only decelerates near stroke end and never locks the load; use an external rod lock or pilot check valve to prevent drift on air loss. Also, this specific SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors without upgrading to the -S variant.
