About the Airtac MIC Cushioned Mini Cylinder MIC25X45SU
Tame high-speed end-of-stroke impacts with the AirTAC MIC25X45SU, a double-acting round-body mini cylinder built with a stainless-steel barrel and rod for mild washdown resistance. It conforms to the ISO 6432 mounting interface for Ø25 bores, dropping cleanly into standard mini-cylinder brackets and clevises. The integrated -S piston magnet supports CMSG, DMSG and EMSG position switches.
At 0.5 MPa this 25 mm bore generates 245.3 N of push force and 206.1 N of pull, yielding a safe working load around 147 N or a vertical lift of roughly 12.5 kg with a 2:1 margin. A needle-set adjustable air cushion at both ends absorbs kinetic energy to protect your payload, while the U-type 90-degree rear cover simplifies port and mounting orientation in compact cells.

Where the Airtac MIC Cushioned Mini Cylinder MIC25X45SU Is Used
Package Diverting
Pushes light cartons at high cycle rates where the adjustable air cushion prevents harsh slams that could damage packaging.
Small Press Ejection
Ejects stamped parts using the 245.3 N push force, relying on the cushion to absorb shock during rapid retraction.
Vertical Lift Gates
Lifts roughly 12.5 kg access doors with a 2:1 safety margin, using the U-type cover for clean 90-degree mounting.
Is the Airtac MIC Cushioned Mini Cylinder MIC25X45SU the Right Cylinder?
Size this 25 mm bore against the adjacent MIC options: step down to the MIC20 for 157.0 N push at 0.5 MPa, or step up to the MIC32 for 402.2 N when you need heavier thrust. The adjustable air cushion is essential here when cycling at high speeds or moving a heavy load, as it decelerates the piston smoothly without relying on a fixed bumper.
Remember that the cushion only slows the stroke near the end and does not lock the rod; if the air supply drops, the piston will drift, so fit an external rod lock or pilot check valve for suspended loads. The -S magnet enables CMSG/DMSG/EMSG sensors, and the 1/8" port matches the standard 25 mm bore specification.
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 MIC25X45SU FAQ
This double-acting cylinder uses a 1/8" port and a 10 mm rod. It generates 245.3 N push and 206.1 N pull at 0.5 MPa, or 343.4 N push and 288.5 N pull at 0.7 MPa. The theoretical maximum force is 50 kgf at 1.0 MPa.
The -S suffix means it has a built-in magnet for CMSG, DMSG or EMSG switches. The adjustable air cushion only decelerates the piston near stroke end to reduce shock; it is not a brake, so the rod will drift on air loss unless you add an external rod lock.
