About the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X125CA
Delivering 25.1 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles compact automation tasks with precision. The riveted round-body construction pairs a corrosion-resistant barrel and rod with a CA pivot clevis, making it highly suitable for damp or washdown environments where painted steel degrades. Because the stroke runs to 125 mm within an 8 mm bore, plan for a safe working load of roughly 15 N rather than the absolute maximum. This translates to lifting about 1.3 kg vertically with a 2:1 safety margin, ensuring the slender 4 mm rod is not over-stressed. Air connects via an M5x0.8 port, and the body conforms to ISO 6432 mounting dimensions for straightforward bracket integration.
This SKU is built without a magnet, so it cannot host CMSG, DMSG, or EMSG reed switches for position sensing. Fixed TPU bumper pads absorb impact energy at the stroke extremes, decelerating the piston smoothly without the adjustable resistance found in the MIC variant. The unit operates efficiently between 30 and 800 mm/s, providing fast cycling for light-duty machinery.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X125CA Is Used
Gripper Actuation
Drives small pneumatic grippers in electronics assembly, using its 25.1 N push force to manipulate lightweight components without damaging them.
Lab Sample Diverting
Pivots on its CA clevis to swing diverter gates in clinical analyzers, benefiting from the stainless build during frequent chemical wipe-downs.
Small Part Ejection
Pushes molded plastic parts out of testing fixtures, utilizing the 125 mm stroke to clear the tooling area completely before the next cycle.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X125CA the Right Cylinder?
When sizing this 8 mm bore, stepping up to the MI12X125 provides a substantial increase to 56.5 N of push force at 0.5 MPa if your mechanism stalls. As the smallest available AirTAC mini cylinder, there is no smaller adjacent option, making this the baseline for minimal footprint tasks. The CA rear clevis allows pivoting articulation, which helps accommodate slight misalignments along the 125 mm travel. Remember that the fixed TPU bumpers only soften end-of-stroke impacts; they do not function as a brake. If the mechanism must hold a vertical load when air pressure drops, install an external pilot-operated check valve or a dedicated rod lock, as the piston will drift otherwise. For position feedback, specify the -S magnet version to enable sensor tracks.
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 MI8X125CA FAQ
At 0.5 MPa, it provides 25.1 N of push and 18.8 N of pull. At 0.7 MPa, push increases to 35.2 N and pull to 26.4 N. The theoretical maximum force is 5.1 kgf at 1.0 MPa. The air port is M5x0.8.
No, this specific SKU lacks the internal magnet required for switches. You must select the -S variant to use CMSG, DMSG, or EMSG sensors. The unit relies on fixed TPU bumper pads for end-of-stroke deceleration.
