Airtac MIC Cushioned Mini Cylinder MIC25X350SU
The AirTAC Airtac MIC Cushioned Mini Cylinder MIC25X350SU is a genuine double acting + cushion round-body mini air cylinder with a Ø25mm bore and 350mm 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 MIC25X350SU
High-speed automation demands smooth stops, and the AirTAC MIC25X350SU delivers exactly that via needle-adjustable air cushions at both ends. This double-acting, round-body stainless steel mini cylinder pairs a 25 mm bore with a 350 mm stroke, yielding 245.3 N of push force and 206.1 N of pull force at 0.5 MPa. Its stainless barrel and rod shrug off mild corrosion and washdown environments, while the 1/8" port and M10x1.25 male rod thread simplify integration.
Built to the ISO 6432 mounting interface, it drops directly into standard mini-cylinder brackets and clevises. The U-style 90-degree rear cover provides flexible port and mounting orientation. With a safe working load around 147 N, it lifts about 12.5 kg vertically with a 2:1 safety margin. The integrated -S piston magnet supports CMSG, DMSG, and EMSG position switches.

Where the Airtac MIC Cushioned Mini Cylinder MIC25X350SU Is Used
Package Diverting
Routes parcels at high speed on a sorting line, using the adjustable cushions to stop the 350 mm stroke gently without jarring the conveyor frame.
Light Pressing
Applies a steady 245.3 N clamping force to seat small electronic components, relying on the stainless build for mild corrosion resistance.
Vertical Lift Stops
Raises lightweight tote bins up to 12.5 kg, with the U-style rear cover easing mounting while the cushions soften the top end impact.
Is the Airtac MIC Cushioned Mini Cylinder MIC25X350SU the Right Cylinder?
If your payload is lighter, the smaller MIC20 bore drops thrust to 157 N at 0.5 MPa, whereas stepping up to the MIC32 raises it to 402 N for heavier moving masses. Choose this 25 mm bore when driving moderate loads at high cycle rates where the adjustable end cushions can be tuned to absorb kinetic energy and protect the mechanism. For position feedback, specify the -S magnet variant to mount CMSG, DMSG, or EMSG sensors.
Remember that the air cushion only decelerates the piston near the stroke end; it is not a brake. If air pressure drops, the piston will drift and cannot hold a load. To prevent vertical dropping or unintended movement, install an external rod lock or a pilot-operated check valve alongside the cylinder.
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 MIC25X350SU FAQ
This double-acting cylinder uses a 1/8" port. At 0.5 MPa it pushes with 245.3 N and pulls with 206.1 N. At 0.7 MPa the push is 343.4 N and pull is 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa.
No. The adjustable air cushion only decelerates the piston near the end of the stroke and acts purely as a shock absorber, never as a brake. If air is lost, the piston will drift. You must add an external rod lock or pilot check valve to hold a vertical load.
