About the Airtac MIC Cushioned Mini Cylinder MIC25X400CM
With 400 mm of travel and a 25 mm bore, this round-body stainless mini cylinder delivers 245.3 N of push force at 0.5 MPa - enough for moderate automation tasks. Its defining feature is the adjustable air cushion at both ends, which lets you fine-tune deceleration via a needle valve, eliminating end-of-stroke shock and noise even at speeds up to 800 mm/s.
The stainless-steel barrel and piston rod offer mild corrosion resistance, making it suitable for humid or washdown environments. It uses the ISO 6432 mini-cylinder mounting interface, so it drops into standard brackets and clevises. The CM back cover provides a round end style. With a 1/8" port and M10x1.25 rod thread, it integrates easily into existing pneumatic circuits.

Where the Airtac MIC Cushioned Mini Cylinder MIC25X400CM Is Used
High-Speed Pick-and-Place
Move lightweight parts at up to 800 mm/s in assembly cells. The adjustable cushion prevents jarring stops, protecting both the payload and the machine frame.
Packaging Line Pushers
Push cartons or pouches into position with 245.3 N force. The stainless build withstands occasional washdowns, and the cushion reduces noise in continuous operation.
Clamping Fixtures
Apply consistent clamping pressure in jigs and fixtures. The 400 mm stroke suits long-travel clamps, while the needle-set cushion gives a controlled, non-impact engagement.
Is the Airtac MIC Cushioned Mini Cylinder MIC25X400CM the Right Cylinder?
For applications requiring moderate force, the MIC25X400CM provides 245.3 N push and 206.1 N pull at 0.5 MPa. If you need less force, the MIC20 bore delivers 157.0 N push at the same pressure; for more power, step up to the MIC32 with 402.2 N push. The adjustable cushion is essential when moving loads at high speed or when shock-sensitive components are involved.
Note that this cylinder does not hold its position on air loss - the piston drifts. For load holding, use an external rod lock or pilot-operated check valve. This SKU has no magnet (-S), so it cannot accept CMSG, DMSG, or EMSG switches. Choose the -S variant if position sensing is required. Mounting options include LB foot, FA flange, SDB pivot-block, 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 MIC25X400CM FAQ
At 0.5 MPa, push is 245.3 N and pull is 206.1 N. At 0.7 MPa, push rises to 343.4 N and pull to 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa. Safe working load is approximately 147 N, and it can lift about 12.5 kg vertically with a 2:1 safety margin.
The MIC25X400CM has a needle-adjustable air cushion at both ends that decelerates the piston near stroke end, reducing shock and noise at high speeds. It is not a lock or brake - the cylinder cannot hold a load on air loss. For position holding, add an external rod lock or pilot-operated check valve. This SKU lacks the -S magnet, so magnetic sensors cannot be mounted on it.
