About the Airtac MIC Cushioned Mini Cylinder MIC40X20SU
Delivering 628.3 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavy-duty automation in compact spaces. The stainless-steel barrel and rod resist mild corrosion and washdown environments. A needle-set variable air cushion at both ends absorbs high-speed end-of-stroke shock, protecting your payload and reducing noise. It features a 1/4" port, a 16 mm piston rod, and a U-style 90-degree rear cover for flexible mounting orientation.
With a theoretical maximum of 128.1 kgf at 1.0 MPa, the unit provides a safe working load of roughly 377 N. This translates to lifting about 32 kg vertically with a 2:1 safety margin. The built-in -S piston magnet enables position sensing with CMSG, DMSG, or EMSG switches.

Where the Airtac MIC Cushioned Mini Cylinder MIC40X20SU Is Used
Heavy Package Diverting
Pushes dense cartons at high speed on a sorting line, using the adjustable cushion to halt the 628 N stroke smoothly without smashing the load.
Case Packing Arms
Drives a folding arm on a packaging machine where the stainless build withstands washdown, while the U cover allows a 90-degree port orientation.
Pallet Stopper Gate
Acts as a heavy pallet stop gate, relying on the 32 kg vertical lift capacity and the end cushions to absorb the kinetic energy of arriving loads.
Is the Airtac MIC Cushioned Mini Cylinder MIC40X20SU the Right Cylinder?
For lighter duties, stepping down to the MIC32 bore drops the 0.5 MPa push force to 402.2 N; there is no larger MIC bore above 40 mm. Choose this 40 mm model when moving heavier masses at high speeds where the adjustable air cushion is essential to prevent impact damage. The cushion only decelerates the piston near the stroke end, so it does not function as a brake. To prevent drift on air loss, add an external rod lock or pilot-operated check valve. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion.
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 MIC Cushioned Mini Cylinder MIC40X20SU FAQ
This 40 mm bore cylinder has a 1/4" port and a 16 mm rod. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical maximum of 128.1 kgf at 1.0 MPa.
Yes, the -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG switches. The adjustable air cushion only decelerates the piston near stroke end to reduce shock; it is not a brake. You need an external rod lock or pilot check valve to hold a load on air loss.
