Airtac MI8~12 Stainless Steel Mini Cylinder MI12X5SU
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI12X5SU is a genuine double acting round-body mini air cylinder with a Ø12mm bore and 5mm stroke, M5×0.8 air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X5SU
Delivering 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles short 5 mm clamping movements with precision. The Ø12 mm bore uses an M5x0.8 port and a Ø6 mm piston rod. Its stainless barrel and rod resist mild corrosion, giving it an edge over painted alternatives in damp environments. The riveted construction keeps the body compact, while fixed TPU bumper pads absorb the impact at the stroke ends.
Because it includes a piston magnet (-S), you can mount CMSG, DMSG or EMSG switches for position sensing. In real-world use, plan for a safe working load of about 34 N at 0.5 MPa. For vertical lifting, this translates to safely raising roughly 2.9 kg with a 2:1 margin. The U back cover provides a 90-degree port orientation, simplifying hose routing in tight machinery.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X5SU Is Used
Micro-Clamping Jaws
Ideal for small pneumatic grippers needing a 5 mm pinch action to hold delicate electronic components during PCB routing.
Ejector Pins
Provides a short 34 N safe push to eject lightweight plastic moulded parts from a fixture without marking the surface.
Sensor Actuation
The 5 mm travel trips mechanical limit switches or small pneumatic valves in densely packed packaging machinery.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X5SU the Right Cylinder?
For a 5 mm stroke, this model provides rapid end-of-travel clamping without taking up much axial room. If your task needs less force, the Ø10 bore provides 39.3 N of push at 0.5 MPa; stepping up to the Ø16 bore yields 100.5 N. This SKU features the -S magnet for sensors and a U rear cover for 90-degree mounting. Remember that a plain cylinder drifts if air pressure drops, as the TPU pads only decelerate the stroke end rather than locking the load. Use a pilot-operated check valve if you must hold a vertical load safely.
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 MI12X5SU FAQ
This Ø12 mm bore cylinder features an M5x0.8 port and generates 56.5 N push / 42.4 N pull at 0.5 MPa, and 79.1 N push / 59.4 N pull at 0.7 MPa. The theoretical maximum force is 11.5 kgf at 1.0 MPa.
Yes, the -S suffix means it has a built-in magnet for CMSG, DMSG or EMSG switches. However, it does not hold position on air loss; the piston drifts and the fixed TPU bumpers only decelerate the stroke end. You need an external rod lock for holding.
