About the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X80SUTC
Generating 25.1 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles precise light-duty actuation. The Ø8 mm bore uses an M5x0.8 port and an 80 mm stroke, relying on fixed TPU bumper pads to decelerate the piston at stroke ends. Its stainless barrel and rod naturally resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. The riveted construction keeps the body compact, and the built-in magnet (-S) supports CMSG, DMSG, or EMSG switches for position sensing.
Because the raw 25.1 N rating leaves little room for friction losses, plan for a safe working load of about 15 N at 0.5 MPa. Vertically, this translates to lifting roughly 1.3 kg with a 2:1 safety margin, letting you match the cylinder to real part weights. The rear U cover provides a 90-degree port orientation, while the included TC trunnion mounting simplifies pivot installations. Furthermore, its ISO 6432 mounting dimensions mean it drops directly into standard mini-cylinder brackets and clevises.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X80SUTC Is Used
Micro-Clamp Actuation
Drives small electronic component clamps on PCB assembly lines, utilizing the 25.1 N push force to secure delicate parts without causing damage.
Lab Dispenser Positioning
Moves lightweight fluid dispenser nozzles in laboratory automation, where the stainless build resists chemical exposure and the 80 mm stroke provides exact linear travel.
Small Part Ejection
Ejects tiny molded plastic parts from testing fixtures, taking advantage of the TC trunnion mount to accommodate the angular ejection path.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X80SUTC the Right Cylinder?
When sizing this 8 mm bore actuator, the next step up is the Ø12 bore, which significantly increases push force to 56.5 N at 0.5 MPa if your load exceeds the 15 N safe working threshold. As the smallest available MI bore, there is no smaller standard option, making this the choice for strictly minimal force applications. The 80 mm stroke is well within the 150 mm standard maximum for this size, though the extended length means you should watch for rod-bending side loads. The TC trunnion pairs with the U back cover for flexible pivoting, and the -S magnet enables CMSG, DMSG, or EMSG sensors.
Remember that a standard double-acting cylinder drifts when air is lost or the valve is centered, as the TPU bumpers only soften the stroke end and act as neither a lock nor a brake. If your application must hold a vertical load securely during a pressure drop, incorporate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
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 MI8X80SUTC FAQ
This double-acting cylinder features an M5x0.8 port and generates a push force of 25.1 N and a pull force of 18.8 N at 0.5 MPa. At 0.7 MPa, the push increases to 35.2 N and the pull to 26.4 N. The theoretical maximum force is 5.1 kgf at 1.0 MPa.
The fixed TPU bumper pads only decelerate the piston at the stroke end and do not function as a lock or brake; the cylinder will drift if air is lost, so an external rod lock or pilot check valve is required for holding. Because this model includes the -S magnet, it fully supports CMSG, DMSG, and EMSG reed or electronic switches for position detection.
