About the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X75SU
Delivering 25.1 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles compact automation tasks with ease. The Ø8 mm bore uses an M5x0.8 air port and an M4x0.7 male rod thread over its 75 mm stroke. Its round-body, riveted construction pairs a stainless barrel and rod to resist mild corrosion and washdowns better than painted alternatives. The built-in magnet (-S) directly supports CMSG, DMSG, and EMSG position switches.
For practical sizing, plan for about 15 N of real work at 0.5 MPa, which safely lifts roughly 1.3 kg vertically with a 2:1 margin. The U back cover provides a 90-degree port orientation for tight spaces, while fixed TPU bumper pads absorb end-of-stroke impacts. It operates at 30-800 mm/s and conforms to ISO 6432 mounting dimensions for easy bracket integration.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X75SU Is Used
Micro-Dispenser Dosing
Actuates a tiny valve for adhesive dosing, using the 75 mm stroke to retract the nozzle cleanly between cycles without stressing the lightweight fixture.
Lab Sample Ejection
Pushes small specimen trays out of a testing carousel, where the stainless body withstands daily chemical wipe-downs and the 15 N safe working load easily moves the trays.
PCB Clamp Release
Cycles a delicate holding arm in an electronics assembly machine, relying on the 90-degree U cover port to keep the pneumatic tubing neatly tucked away.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X75SU the Right Cylinder?
As the smallest available AirTAC mini cylinder, the Ø8 bore leaves no smaller MI option if the 25.1 N push at 0.5 MPa proves insufficient; stepping up to the Ø10 bore raises that push to 39.3 N. The 75 mm stroke is well within the 150 mm standard maximum, keeping the rod bending risk low. Because the U cover orients the M5x0.8 port at 90 degrees, verify your manifold clearance before routing air lines.
Remember that fixed TPU bumpers only decelerate the stroke end; they do not lock the piston. If your process drops air or centres the valve, the rod will drift. To hold a vertical load securely, add an external rod lock or a pilot-operated check valve to the circuit.
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 MI8~12 Stainless Steel Mini Cylinder MI8X75SU FAQ
At 0.5 MPa it provides 25.1 N push and 18.8 N pull; at 0.7 MPa it provides 35.2 N push and 26.4 N pull. The theoretical maximum force is 5.1 kgf at 1.0 MPa. The air port is M5x0.8.
Yes, the -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG switches. However, it does not hold position if air is lost; the fixed TPU bumpers only decelerate the stroke end. Use a pilot check valve for load holding.
