About the Airtac MIC Cushioned Mini Cylinder MIC25X90SU
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless steel round-body mini cylinder handles demanding 90 mm stroke tasks. 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 your payload and reducing noise far better than a fixed rubber bumper.
Built with a stainless barrel and rod, it resists mild corrosion and washdown environments. It uses the standard ISO 6432 mounting interface for Ø25 bores, dropping easily into existing mini-cylinder brackets. This SKU includes a piston magnet (-S) for CMSG, DMSG or EMSG position sensing, and features a U-style 90-degree rear cover. With a 1/8" port and M10x1.25 male rod thread, it lifts about 12.5 kg vertically with a 2:1 safety margin.

Where the Airtac MIC Cushioned Mini Cylinder MIC25X90SU Is Used
Package Diverting
Uses the 245 N push force to deflect medium-weight cartons on a high-speed line, relying on the tuned air cushion to stop the 90 mm stroke smoothly without slamming.
Filler Head Actuation
Drives a vertical filling nozzle up and down, where the stainless build resists washdown and the adjustable cushion prevents liquid splashing at rapid stroke ends.
Small Part Ejection
Pushes assembled components out of a jig at 800 mm/s, using the needle valve to decelerate the load gently before it hits the end cap.
Is the Airtac MIC Cushioned Mini Cylinder MIC25X90SU the Right Cylinder?
When sizing this 90 mm stroke unit, consider the force curve. Stepping down to the MIC20 gives 157 N push at 0.5 MPa, while moving up to the MIC32 provides 402 N if you need heavier thrust. Choose this Ø25 bore when your payload approaches the 147 N safe working load threshold and cycle speeds are high enough that the adjustable needle cushion genuinely matters. The U-style back cover simplifies 90-degree mounting orientations.
Remember that the air cushion only decelerates the piston near the stroke end; it does not act as a brake or lock. If air pressure drops, the piston will drift, so fit an external rod lock or pilot-operated check valve to hold a suspended load. Because this model carries the -S suffix, you can directly mount CMSG, DMSG or EMSG sensors for precise switching.
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 MIC25X90SU FAQ
This double-acting cylinder has a 1/8" port and generates 245.3 N push and 206.1 N pull at 0.5 MPa. At 0.7 MPa it provides 343.4 N push and 288.5 N pull. The theoretical maximum force is 50 kgf at 1.0 MPa.
Yes, 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. The cylinder will drift on air loss, so use an external rod lock to hold a load.
