About the Airtac MIC Cushioned Mini Cylinder MIC40X225SU
Delivering 628.3 N of push force at 0.5 MPa, the AirTAC MIC40X225SU is a robust double-acting round-body mini cylinder built for demanding motion tasks. It features a stainless-steel barrel and piston rod that resist mild corrosion and washdown environments. A 1/4" port feeds the 16 mm rod, and the U-style back cover provides a 90-degree mounting orientation for tight machinery layouts.
The defining feature of this 40 mm bore unit is the adjustable air cushion at both ends. By turning a needle valve, you tune the deceleration to absorb end-of-stroke shock at speeds up to 800 mm/s, protecting the load and reducing noise versus a fixed bumper. Factoring a 2:1 safety margin, it lifts about 32 kg vertically, giving a safe working load of roughly 377 N.

Where the Airtac MIC Cushioned Mini Cylinder MIC40X225SU Is Used
Heavy Carton Diversion
Swiftly deflects heavy packaged goods on a high-speed sorting line, using the adjustable cushion to prevent harsh slams when shifting the 32 kg load.
Vertical Flap Folding
Drives carton flaps downward rapidly on a packing machine, relying on the needle-set cushion to soften the end stop and protect the packaging mechanics.
Component Pressing
Applies a steady 628.3 N push to seat bearings or pins into housings, with the stainless build enduring light coolant splash in a machining cell.
Is the Airtac MIC Cushioned Mini Cylinder MIC40X225SU the Right Cylinder?
When sizing this 40 mm bore actuator, compare it against the adjacent MIC32 option, which yields 402.2 N of push force at 0.5 MPa. Since the MIC40 is the largest available bore in this series, moving beyond 628.3 N requires switching to a different cylinder family entirely. Select this model when driving heavier masses at high cycling speeds where the adjustable cushion can be finely tuned to prevent harsh impacts.
Remember that the air cushion only decelerates the piston near the stroke end; it does not function as a brake. If your application must hold a load vertically during a loss of air pressure, add an external rod lock or pilot-operated check valve. This SKU includes the -S magnet for position sensing with CMSG, DMSG, or EMSG switches, and accepts LB foot, FA flange, SDB pivot, or TC trunnion mounts.
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 MIC40X225SU FAQ
This 40 mm bore cylinder features 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 force of 128.1 kgf at 1.0 MPa.
No, the adjustable air cushion only decelerates the piston near the stroke end and acts purely as a shock absorber, never as a lock. To prevent drift on a vertical load during air loss, install an external rod lock or pilot check valve. The built-in -S magnet supports CMSG, DMSG, and EMSG sensors.
