Airtac MIC Cushioned Mini Cylinder MIC25X225SU
The AirTAC Airtac MIC Cushioned Mini Cylinder MIC25X225SU is a genuine double acting + cushion round-body mini air cylinder with a Ø25mm bore and 225mm 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 MIC25X225SU
Delivering 245.3 N of push force at 0.5 MPa, the AirTAC MIC25X225SU is a double-acting, round-body stainless steel mini cylinder built for a 225 mm stroke. The stainless barrel and piston rod supply mild corrosion resistance for washdown environments, while the U-style back cover provides a 90-degree port and mounting orientation. Because this is a 25 mm bore, it conforms to the ISO 6432 mini-cylinder mounting interface, dropping directly into standard mini brackets and clevises.
The defining feature of the MIC series is the adjustable air cushion at both ends. By turning a needle valve, you tune the end-of-stroke deceleration to absorb high-speed shock, protecting the load and reducing noise far better than a fixed rubber bumper. In practical terms, this cylinder handles a safe working load of about 147 N (roughly 60% of its 0.5 MPa push rating) and lifts about 12.5 kg vertically with a 2:1 safety margin. It includes a built-in piston magnet (-S) for position sensing.

Where the Airtac MIC Cushioned Mini Cylinder MIC25X225SU Is Used
Package Diverting
Uses the 245.3 N push force at 0.5 MPa to deflect medium-weight cartons on a high-speed sorting line, relying on the adjustable cushion to prevent harsh slams at the 225 mm stroke end.
Vertical Lift Gates
Raises access gates or light barriers weighing up to 12.5 kg, where the stainless build resists humidity and the needle-set cushion softens the rapid descent.
Film Roll Tensioning
Maintains precise tension on packaging webs, using the 206.1 N pull force and the 90-degree U back cover to fit neatly into a compact machine frame.
Is the Airtac MIC Cushioned Mini Cylinder MIC25X225SU the Right Cylinder?
When sizing this 25 mm bore, stepping down to the MIC20 drops the 0.5 MPa push force to 157 N, while stepping up to the MIC32 raises it to 402 N. Choose this 225 mm stroke model when moving loads at high speeds where the adjustable air cushion is required to prevent harsh end-of-stroke impacts. The 1/8" port matches the standard 25 mm bore sizing.
Remember that the air cushion only decelerates the piston near the stroke end; it does not function as a lock or brake. If air pressure drops, the piston will drift, so fit an external rod lock or pilot-operated check valve if you need to hold a load vertically. The -S magnet allows CMSG, DMSG, or EMSG switches for sensing, and you can mount it via LB foot, FA flange, SDB pivot, or 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 MIC25X225SU FAQ
This 25 mm bore cylinder features a 1/8" port and an M10x1.25 male rod thread. At 0.5 MPa it provides 245.3 N of push force and 206.1 N of pull force. At 0.7 MPa, push increases to 343.4 N and pull to 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 stroke; it is not a brake and will not hold a load if air pressure is lost. You will need an external rod lock or pilot check valve for holding. Because this SKU includes the -S magnet, you can mount CMSG, DMSG, or EMSG switches for position sensing.
