About the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X15U
Generating 25.1 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles tiny actuation jobs with precision. The Ø8 mm bore uses an M5x0.8 port and a 4 mm rod. Its stainless barrel and rod resist mild corrosion, offering a real advantage over painted alternatives in damp environments. The riveted construction keeps the body compact, while fixed TPU bumper pads absorb impact at the stroke ends.
For practical sizing, plan for about 15 N of actual work at 0.5 MPa, which safely lifts roughly 1.3 kg vertically. This SKU features a U-type back cover for 90-degree mounting orientation. Because it lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG sensors.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X15U Is Used
Micro Ejector Pins
Provides the 15 N safe working force needed to actuate tiny ejection pins in compact injection mould tooling.
Lab Dispenser Diverter
The stainless build survives mildly humid lab environments while routing small fluid lines via a 90-degree pivot.
PCB Clamp Release
Delivers precise 1.3 kg vertical lift to hold and release delicate printed circuit boards during automated testing.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X15U the Right Cylinder?
If 25.1 N at 0.5 MPa is insufficient, step up to the Ø10 bore (39.3 N push); if you need less force, the Ø8 is the smallest available MI option. This U-cover model mounts at 90 degrees, but you can also use LB foot, FA flange, SDB pivot or TC trunnion brackets. Remember that a plain cylinder drifts when air is lost or a valve is centred; the bumper pads only decelerate the stroke end and do not act as a lock. For a held load, specify an external rod lock or pilot check valve.
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 MI8X15U FAQ
This Ø8 mm bore cylinder features an M5x0.8 port. It generates 25.1 N push and 18.8 N pull at 0.5 MPa, 35.2 N push and 26.4 N pull at 0.7 MPa, with a theoretical maximum of 5.1 kgf at 1.0 MPa.
No, this specific SKU lacks a magnet and cannot accept CMSG, DMSG or EMSG switches. You must order the -S variant for position sensing. It uses standard ISO 6432 mounting dimensions and fixed TPU bumper pads.
