About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X300SCA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 300 mm stroke with a Ø10 mm piston rod. The riveted barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Its 1/8" port feeds air to extend and retract the rod, while fixed TPU bumper pads absorb the impact at stroke ends.
Thanks to the built-in -S piston magnet, you can mount CMSG, DMSG or EMSG switches for position sensing. Operating at 0.15-1.0 MPa, the unit yields a practical safe working load of roughly 147 N. In vertical lift setups, it lifts about 12.5 kg with a 2:1 safety margin. The CA rear cover provides a pivot clevis for articulated mounting.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X300SCA Is Used
Package Diverting Gate
Swings a sorting flap on a packaging line using the CA pivot mount, relying on the 245.3 N push force to redirect heavy cartons at high speed.
Pallet Load Pusher
Strokes 300 mm to index goods off a roller conveyor, where the stainless build resists humidity and the fixed TPU pads absorb the end-of-stroke impact.
Textile Loom Tensioner
Modulates yarn tension via a DMSG sensor on the magnet piston, moving 12.5 kg of guide mass vertically with a safe 2:1 lift margin.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X300SCA the Right Cylinder?
When sizing this 25 mm bore, the smaller Ø20 generates 157 N of push at 0.5 MPa, whereas stepping up to the non-ISO Ø32 yields 402 N. If air pressure drops or the valve centres, this cylinder cannot hold position and the piston will drift; the bumpers only decelerate the end of travel. For suspended loads, specify an external rod lock or pilot check valve.
The CA pivot back cover suits articulated joints, and you can pair it with LB foot, FA flange, SDB pivot or TC trunnion brackets. The -S magnet enables CMSG/DMSG/EMSG sensors. At 300 mm of travel, mind the rod-bending side loads—keep the guide alignment tight to prevent rod wear.
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 MI25~40 Stainless Steel Mini Cylinder MI25X300SCA FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N. At 0.7 MPa it pushes 343.4 N and pulls 288.5 N. The theoretical max force is 50 kgf at 1.0 MPa. It uses a 1/8" air port and a Ø10 mm rod with an M10x1.25 male thread.
No, it uses fixed TPU bumper pads that decelerate the piston at the stroke ends. It is not an adjustable air cushion variant like the MIC. It conforms to ISO 6432 mounting dimensions for standard mini brackets, and the -S magnet allows CMSG, DMSG or EMSG sensors.
