About the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X150
Twin guiding rods and adjustable air cushions define the AirTAC MICD40X150, a stainless round-body mini cylinder built for fast, shock-sensitive moves. Because a rod exits both covers, the working area is identical in both directions, yielding an equal force of 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa. The 1/4" port feeds the 16 mm rod to deliver this thrust smoothly across a 150 mm stroke.
The stainless steel barrel and piston rod resist mild corrosion and washdown environments. For practical sizing, a safe working load is roughly 317 N (about 60% of the 0.5 MPa figure), which translates to a vertical lift capacity of about 26.9 kg with a 2:1 safety margin. Note this base SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors without upgrading to the -S variant.

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 MICD40X150 Is Used
Diverting Heavy Cartons
Equal 527.8 N force both ways makes the twin rods ideal for pushing weighted boxes off a high-speed belt without rotational drift.
Pallet Stopper Arm
The adjustable air cushion absorbs the impact of a moving pallet hitting the stop, while the 150 mm stroke clears the conveyor path.
Guided Lift Gate
Lifts roughly 26.9 kg vertically with a 2:1 margin; the dual rods prevent the gate from binding under off-center loads.
Is the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X150 the Right Cylinder?
When sizing this 40 mm bore, stepping down to the MICD32 cuts the 0.5 MPa force to 345.6 N, while no larger MICD bore exists if you need more than 527.8 N. Choose this double-rod plus cushion configuration when a load requires anti-rotation guidance and rapid cycling that would otherwise slam harshly into the end caps. The needle-set air cushions decelerate the piston near stroke end but do not lock or hold the load; if position holding on air loss is required, fit an external rod lock or pilot check valve.
Mounting options include LB foot, FA flange and TC trunnion, while back covers offer CA, U, R or CM configurations. The SDB pivot block is not available on this double-rod variant. Additionally, because this specific SKU is non-magnetic, it cannot support position sensing.
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 MICD40X150 FAQ
It generates 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa, with a maximum theoretical force of 107.6 kgf at 1.0 MPa. Because it is a double-rod cylinder, this force is identical in both directions. The air port is 1/4".
No, this base SKU does not include a magnet and cannot accept CMSG, DMSG or EMSG switches. You must select the -S variant for sensing. The adjustable air cushions at both ends only decelerate the piston near stroke end and do not function as a lock or brake.
