About the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X50SCA
Delivering 25.1 N of push force at 0.5 MPa, this AirTAC MI8X50SCA mini cylinder is built for compact automation. The riveted stainless-steel barrel and Ø4 mm rod shrug off mild washdown and damp environments where painted bodies fail. Its ISO 6432 mounting interface lets you drop it straight into standard mini-cylinder brackets and clevises.
The integrated -S piston magnet supports CMSG, DMSG and EMSG switches for position sensing. Fixed TPU bumper pads absorb stroke-end impact across the 50 mm travel. Plan for roughly 15 N of actual work at 0.5 MPa, which means it lifts about 1.3 kg vertically with a 2:1 safety margin.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X50SCA Is Used
Micro-Clamp Actuation
Drives tiny pneumatic clamps in electronics assembly fixtures, using its 15 N safe working load to hold delicate PCBs without crushing them.
Light-Part Ejection
Pushes small plastic or stamped metal parts out of a die, relying on the 25.1 N push force at 0.5 MPa to clear the tooling reliably.
Lab Dispenser Routing
Pivots fluid nozzle brackets via the CA clevis, with the stainless build resisting chemical mist in analytical diagnostic machines.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X50SCA the Right Cylinder?
As the smallest bore in the MI family, the Ø8 steps up to the Ø12 (56.5 N push @0.5 MPa) when you need more force. The CA rear pivot cover on this SKU suits articulated or pivoting rod-end linkages. For position feedback, the internal magnet pairs directly with reed or electronic sensors.
Air pressure alone will not hold this cylinder's position if the valve is centred or air is lost; the piston drifts and the TPU pads only decelerate the end of stroke. Fit an external pilot check valve or rod lock if your mechanism must resist gravity. Keep side-loads minimal on this 50 mm stroke to avoid bending the Ø4 mm rod.
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 MI8X50SCA FAQ
It generates 25.1 N push and 18.8 N pull at 0.5 MPa, and 35.2 N push / 26.4 N pull at 0.7 MPa. The theoretical maximum force is 5.1 kgf at 1.0 MPa. The air port is M5x0.8.
It uses fixed TPU bumper pads to decelerate the stroke end, not an adjustable air cushion. Because this SKU includes the -S magnet, you can mount CMSG, DMSG or EMSG switches for position detection.
