About the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X220SCA
Delivering 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation tasks with ease. The Ø12 mm bore uses an M5x0.8 air port and a male M6x1.0 rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted-steel minis in damp or washdown environments. Fixed TPU bumper pads soften the impact at stroke ends, while the riveted body stays light and space-efficient.
Because it carries the -S suffix, this unit includes a built-in piston magnet for CMSG, DMSG, or EMSG switches. For practical sizing, plan for roughly 34 N of real work at 0.5 MPa, which means it lifts about 2.9 kg vertically with a 2:1 safety margin. The CA back cover provides a pivot clevis mount, and the body conforms to ISO 6432 mounting dimensions for straightforward bracket integration.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X220SCA Is Used
PCB Depaneling Router
Pushes a 220 mm carriage to separate routed circuit boards, using the 2.9 kg vertical lift capacity to handle light tooling fixtures safely.
Sorting Diverter Gate
Actuates a lightweight aluminum flap to route small plastic parts on a belt line, relying on the CA clevis to handle pivot stress.
Flow-Wrap Film Guide
Adjusts a packaging film tensioner bar in damp food-packing zones where the stainless steel barrel prevents mild corrosion.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X220SCA the Right Cylinder?
When sizing this 56.5 N (at 0.5 MPa) unit, stepping down to the Ø8 bore drops output to 25.1 N, while moving up to the Ø16 bore increases it to 100.5 N. The 220 mm stroke is well within the 250 mm standard limit for this bore, but at that length you should minimize side-loading to prevent rod bending. The CA rear clevis helps absorb angular misalignment during the stroke.
This SKU includes the -S magnet for position sensing, but a plain MI cannot hold its load if air pressure drops or the valve is centered—the piston will drift. The TPU bumpers only decelerate the stroke end rather than acting as a brake. To lock a load in place, install an external rod lock or a pilot-operated 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 MI12X220SCA FAQ
At 0.5 MPa it provides 56.5 N push and 42.4 N pull. At 0.7 MPa it provides 79.1 N push and 59.4 N pull. The theoretical maximum force is 11.5 kgf at 1.0 MPa. The air port is M5x0.8.
No, the piston drifts on air loss and the fixed TPU bumper pads only decelerate the stroke end without locking the load; use an external rod lock or pilot check valve for holding. It includes a magnet for CMSG/DMSG/EMSG sensors and uses standard ISO 6432 mounting dimensions.
