About the Airtac MIC Cushioned Mini Cylinder MIC25X115SU
Built for shock-sensitive automation, this stainless-steel round-body mini cylinder delivers 245.3 N of push force at 0.5 MPa. The defining trait of the MIC line is its variable air cushion at both ends. By turning a needle valve, you tune the end-of-stroke deceleration to absorb kinetic energy at high speeds, protecting the load and lowering noise far better than a fixed rubber bumper. The Ø25 bore uses a 1/8" port and an M10x1.25 male rod thread.
The stainless barrel and piston rod shrug off mild corrosion and washdown environments. Because the bore falls in the Ø16 to Ø25 range, it conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets and clevises. This specific SKU includes the -S piston magnet for position sensing and a U-type back cover that presents the port at 90 degrees for tight layouts. In practical terms, it yields a safe working load of roughly 147 N, lifting about 12.5 kg vertically with a 2:1 safety margin.

Where the Airtac MIC Cushioned Mini Cylinder MIC25X115SU Is Used
Package Diverting
Handles 12.5 kg cartons at high speed on a sorting line, using the needle cushion to stop the stroke smoothly without jarring the conveyor belt.
Component Seating
Presses lightweight bearings into housings on an automated assembly line, relying on the 245.3 N push force and ISO 6432 mounting for easy integration.
Vertical Lift Gates
Raises and lowers access flaps in washdown zones where the stainless build resists mild corrosion and the U cover keeps ports compact.
Is the Airtac MIC Cushioned Mini Cylinder MIC25X115SU the Right Cylinder?
If 245.3 N of push at 0.5 MPa is too much, step down to the MIC20, which provides 157.0 N; if you need more muscle, the MIC32 offers 402.2 N. The adjustable cushion matters most when driving heavy loads at high speeds up to 800 mm/s, preventing harsh impacts. Remember that the cushion only decelerates the piston near the stroke end—it does not lock the rod. If the machine loses air, the piston drifts, so fit an external rod lock or pilot check valve to hold a suspended load. This model carries the -S magnet for CMSG, DMSG, or EMSG switches, and the U back cover simplifies plumbing in confined spaces.
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 MIC25X115SU FAQ
This double-acting cylinder uses a 1/8" port and an M10x1.25 male rod thread. 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 the pull is 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa.
It features a needle-adjustable air cushion at both ends that decelerates the piston near the stroke end to cut shock, but it is not a brake. Because this model includes the -S magnet, you can mount CMSG, DMSG, or EMSG switches for position detection.
