Airtac MIC Cushioned Mini Cylinder MIC25X400CA
The AirTAC Airtac MIC Cushioned Mini Cylinder MIC25X400CA is a genuine double acting + cushion round-body mini air cylinder with a Ø25mm bore and 400mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MIC Cushioned Mini Cylinder MIC25X400CA
Handling a 400 mm stroke with a 245.3 N push force at 0.5 MPa, the AirTAC MIC25X400CA is a double-acting round-body mini cylinder built from stainless steel. The CA rear pivot cover simplifies clevis mounting for articulated loads, and the 1/8" port drives the 10 mm rod.
Unlike a fixed-bumper unit, this model features an adjustable air cushion at both ends. Turning the cushion needle lets you tune end-of-stroke deceleration to cut shock and noise at high speeds. The stainless barrel and rod shrug off mild washdown corrosion. With a 245.3 N push force, it provides a safe working load of about 147 N, lifting roughly 12.5 kg vertically with a 2:1 margin. Note that this specific SKU lacks a magnet, so it cannot host CMSG or DMSG sensors.

Where the Airtac MIC Cushioned Mini Cylinder MIC25X400CA Is Used
Pivoted Parts Ejection
Uses the CA clevis cover to swing and eject 12 kg formed parts from a press over the 400 mm travel, relying on tuned cushions to stop the swing smoothly.
High-Speed Diverting
Pushes packages across a belt at 800 mm/s; the adjustable air cushions absorb the kinetic energy of the 245 N thrust to prevent end-cap damage.
Washdown Gate Actuation
Stainless construction resists mild moisture in a dispatch area, moving a sorting gate through 400 mm while the needle valves dial in a soft landing.
Is the Airtac MIC Cushioned Mini Cylinder MIC25X400CA the Right Cylinder?
For lighter duty, the MIC20X400CA pushes 157 N at 0.5 MPa, whereas stepping up to the MIC32X400CA yields 402 N if your load exceeds 245 N. The adjustable cushion proves essential when moving heavier masses at high velocities, as it prevents harsh end-of-stroke impacts. Because this is a non-magnetized unit, position sensing is unavailable; order the -S variant to enable CMSG or EMSG switches. Remember that the air cushion only decelerates the piston near stroke end and does not lock the rod. To prevent drift on air loss, fit an external rod lock or pilot check valve.
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 MIC25X400CA FAQ
This 25 mm bore cylinder uses a 1/8" port and an M10x1.25 male rod thread. It generates a push force of 245.3 N and a pull force of 206.1 N at 0.5 MPa. At 0.7 MPa, push is 343.4 N and pull is 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so CMSG, DMSG, or EMSG switches cannot be used. You would need the -S variant for position sensing. The adjustable air cushion at both ends functions solely to decelerate the load, not to hold it in place.
