About the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X125
Twin piston rods exit both covers on this stainless-steel round-body mini cylinder, ensuring equal force in both directions and resisting rotation. The adjustable air cushion at each end soaks up high-speed end-of-stroke shock, making it ideal for guided, shock-sensitive moves. This 40 mm bore unit delivers 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa, with a 1/4 inch port and M12x1.25 male rod thread.
Built with a stainless barrel and rod for mild corrosion and washdown resistance, it operates at 30-800 mm/s. Because a rod occupies both faces, the pull-side area dictates the thrust. For lifting tasks, expect a safe working load of about 317 N, which translates to moving roughly 26.9 kg vertically each way with a 2:1 safety margin. Note this non-magnetic SKU cannot take a sensor; the -S variant is required for CMSG, DMSG or EMSG 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 MICD40X125 Is Used
Pallet Transfer Stopper
Halts heavy pallets on a conveyor using the 527.8 N bidirectional force, while the twin rods resist side loads and the adjustable cushion absorbs the impact.
Vertical Lift Gate
Raises and lowers a 26 kg guided gate at speed. The equal both-ways thrust keeps motion smooth, and the needle-set cushion prevents slamming at stroke end.
Carton Flap Folder
Folds heavy packaging flaps simultaneously from both sides. The stainless build handles washdown, and the double-rod design ensures the flaps meet perfectly without twisting.
Is the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X125 the Right Cylinder?
When sizing both ways, the smaller MICD32 bore yields 345.6 N at 0.5 MPa, while the MICD40 is the largest available in this cushioned series. Choose this 40 mm model when your application demands the maximum 527.8 N thrust both ways alongside shock absorption. The twin-rod layout prevents twisting, but remember the air cushion only decelerates near stroke end and does not lock the load. If air pressure drops, the piston will drift. Use an external rod lock or pilot check valve for position holding.
Mounting options include LB foot, FA flange and TC trunnion blocks; the SDB pivot block is not offered on this double-rod variant. Back covers available are CA, U, R and CM. Since this specific SKU lacks the -S magnet, it cannot support magnetic 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 MICD40X125 FAQ
The force is equal both ways because a rod exits both ends. It provides 527.8 N at 0.5 MPa, 738.9 N at 0.7 MPa, and a maximum theoretical force of 107.6 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet and cannot take a switch. You must order the -S variant to use CMSG, DMSG or EMSG sensors. The adjustable air cushion at both ends only decelerates the load and does not act as a lock.
