About the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X175S
Twin rods exit both covers of this stainless round-body mini cylinder, yielding equal 527.8 N force at 0.5 MPa on extension and retraction while preventing rotation. An adjustable air cushion at each end soaks up end-of-stroke shock, making the unit suited for fast, guided moves. The 40 mm bore uses a 1/4" port and a 16 mm piston rod with an M12x1.25 male thread.
Because the -S suffix includes a piston magnet, you can mount CMSG, DMSG or EMSG switches for position sensing. The stainless steel barrel and rod resist mild corrosion and washdown. For sizing, a safe working load is about 317 N, which means it can vertically lift roughly 26.9 kg with a 2:1 safety margin. Note that the cushion only decelerates the piston near the stroke end; it does not lock or hold 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 MICD40X175S Is Used
Package Diverting
Equal force both ways and twin rods make this 40 mm bore cylinder ideal for rapidly diverting heavy cartons on a conveyor without rotational deflection.
Pallet Stopper
The adjustable air cushions absorb the end-of-stroke impact when stopping pallets, while the 527.8 N force handles substantial loads at 0.5 MPa.
Guided Clamping
Stainless construction and a through-rod design provide stable, corrosion-resistant clamping on automated machining lines where a back rod trips a remote switch.
Is the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X175S the Right Cylinder?
If you need less push, the smaller MICD32 bore provides 345.6 N at 0.5 MPa; this 40 mm bore is the largest available in the series, so no larger MICD option exists. Choose this double-rod and adjustable-cushion combination when your application demands high-speed travel with shock absorption and resistance to twisting. You can mount it using LB foot, FA flange or TC trunnion brackets, but the SDB pivot block is not offered on this double-rod variant.
The built-in magnet enables CMSG, DMSG or EMSG sensors for precise switching. Remember that a standard cylinder drifts when air pressure drops, so install an external rod lock or pilot check valve if you must hold a load vertically during a power loss.
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 MICD40X175S FAQ
Force is equal both ways because a rod exits both ends. 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.
No, the piston will drift on air loss. The adjustable air cushions only decelerate the piston near the stroke end and do not act as a lock. Use an external rod lock or pilot check valve to hold loads.
