About the Airtac MIC Cushioned Mini Cylinder MIC40X300SU
With a 628.3 N push at 0.5 MPa, this 40 round-body mini cylinder handles substantial loads in tight spaces. The stainless-steel barrel and rod shrug off mild corrosion, making it a fit for washdown areas where plated cylinders might rust.
The adjustable air cushion at both ends is the defining feature - a needle valve lets you tune deceleration to kill end-of-stroke shock at high speed. That translates to quieter operation and less wear on your tooling. The built-in magnet (-S) accepts CMSG, DMSG, or EMSG switches for position sensing. Port is 1/4" PT or G.

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 | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
| Max (@1.0 MPa) | 128 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MIC Cushioned Mini Cylinder MIC40X300SU Is Used
High-Speed Pick-and-Place
The 628.3 N push at 0.5 MPa handles parts up to about 32 kg with margin. Adjustable cushions tame the impact at both ends, protecting grippers and fragile components during rapid cycling.
Carton Ejection
Push 879.6 N at 0.7 MPa to shove packed cartons off a conveyor. The needle-set cushion prevents the load from slamming at stroke end, reducing noise and box damage.
Washdown Zone Actuation
Stainless barrel and rod resist mild corrosion from cleaning agents. The 1/4" port and U back cover simplify plumbing in tight machine frames where hoses route at 90 degrees.
Is the Airtac MIC Cushioned Mini Cylinder MIC40X300SU the Right Cylinder?
This 40 mm bore delivers 628.3 N push and 527.8 N pull at 0.5 MPa - roughly 32 kg of vertical lift with a 2:1 safety margin. If you need less force, the 32 MIC produces 402.2 N push at the same pressure; there is no larger MIC bore, so step up to a different series for more thrust.
The cushion really earns its keep on high-speed cycles or when moving fragile loads - dial the needle to ease into the stroke end. Remember, the cushion only decelerates; it won't hold a load if air pressure drops. For vertical applications where drift is dangerous, add an external rod lock or pilot check valve. The U back cover gives you 90-degree port orientation for tight plumbing. With the -S magnet, you can mount CMSG, DMSG, or EMSG switches for reliable position feedback.
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 MIC40X300SU FAQ
At 0.5 MPa, push is 628.3 N and pull is 527.8 N. At 0.7 MPa, push rises to 879.6 N and pull to 738.9 N. Theoretical maximum thrust is 128.1 kgf at 1.0 MPa. Safe working load is about 377 N (60% of the 0.5 MPa push figure).
A needle valve at each end meters exhaust air to decelerate the piston smoothly near stroke end - reducing shock and noise at high speed. It only slows the piston; it does not lock or hold a load. If air pressure drops, the piston drifts. For load holding, use an external rod lock or pilot check valve.
