About the Airtac MIC Cushioned Mini Cylinder MIC40X50CM
The adjustable air cushion at both ends is what sets the MIC40X50CM apart from a standard bumper mini cylinder. A needle valve on each end cap lets you dial in the deceleration, turning high-speed end-of-stroke impacts into smooth stops that protect your tooling and cut noise. This 40 mm bore unit delivers 628.3 N of push force at 0.5 MPa, making it a solid choice for medium-duty automation tasks.
Its stainless-steel round body and piston rod shrug off mild corrosion and washdown splashes, which suits food-adjacent or humid production areas. The CM back cover provides a clean, rounded rear end that simplifies mounting orientation. With a safe working load of about 377 N (roughly 60% of the 0.5 MPa push force), you can confidently drive moderate loads without oversizing. Air connection is a 1/4" port, standard for this bore class.

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 MIC40X50CM Is Used
Packaging Line Stop Gates
Use the MIC40X50CM to operate a stop gate on a conveyor. The 628.3 N push force at 0.5 MPa easily lifts a 32 kg gate, while the adjustable cushion prevents the gate from jarring the product at the end of each cycle.
Press Platen Cushioning
In a small pneumatic press, this cylinder's 879.6 N push at 0.7 MPa provides the pressing force. The needle-adjustable cushion at both ends lets you tune the return stroke to avoid hammering the frame, extending machine life.
Vertical Lift Assist
For a lifting application, the MIC40X50CM can raise about 32 kg vertically with a 2:1 safety margin. The cushion absorbs the shock when the lift reaches its top stop, reducing noise and protecting the load from sudden deceleration.
Is the Airtac MIC Cushioned Mini Cylinder MIC40X50CM the Right Cylinder?
When sizing, compare the MIC40X50CM's 628.3 N push force against your actual load. If you need less than 500 N of force, the MIC32X75S with its 402.2 N push at 0.5 MPa might save space and cost. There is no larger bore in the MIC cushion series, so if you need more than 879.6 N at 0.7 MPa, you would need to step up to a different cylinder family. The adjustable cushion becomes essential when you're running at speeds above 300 mm/s or moving heavier loads that can slam at the end of stroke.
Remember, this cylinder does not hold its position if air pressure drops-the piston will drift. For a load that must stay put, you'll need an external rod lock or a pilot-operated check valve. This SKU has no magnetic piston, so it cannot accept CMSG, DMSG, or EMSG sensors; choose the -S version if you need position sensing. The CM back cover and 1/4" ports are fixed, but you can select from LB foot, FA flange, SDB pivot-block, 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 MIC40X50CM FAQ
At 0.5 MPa, the push force is 628.3 N and the pull force is 527.8 N. At 0.7 MPa, push is 879.6 N and pull is 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa. The safe working load is approximately 377 N, which is 60% of the 0.5 MPa push force.
The air cushion uses a needle valve at each end to control the exhaust flow near stroke end, decelerating the piston smoothly. It is not a lock or brake. This specific model (without -S) has no magnetic piston, so it cannot use CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing.
