About the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X80SU
Delivering 25.1 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact actuation with ease. The Ø8 mm bore features an M5x0.8 port and an 80 mm stroke, utilizing a built-in piston magnet for CMSG, DMSG, or EMSG switches. Its stainless barrel and rod resist mild corrosion, making it superior to painted alternatives in damp environments.
Designed with a 90-degree U back cover, it fits into tight spaces while offering practical output. Plan for roughly 15 N of actual work at 0.5 MPa, which translates to lifting about 1.3 kg vertically with a safe 2:1 margin. Fixed TPU bumper pads absorb end-of-stroke impacts, ensuring smooth operation across the 30-800 mm/s speed range.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X80SU Is Used
Pick-and-Place Ejection
Provides the 15 N working force needed to push small molded plastic parts out of an injection mold tool on a 80 mm stroke.
Package Diverting
Actuates a lightweight routing flap on a conveyor belt, using its stainless build to withstand humid packing facility washdowns.
Lab Sample Handling
Shifts small vials 80 mm between testing stations, benefiting from the 1.3 kg vertical lift capacity and CMSG sensor integration.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X80SU the Right Cylinder?
When sizing this actuator, consider the next bore up: the Ø10 MI generates 39.3 N of push at 0.5 MPa if your load exceeds the 15 N practical working threshold. As the smallest available MI bore, there is no smaller option. The 80 mm stroke is well within the 150 mm maximum standard stroke, keeping the assembly compact.
This SKU includes the -S magnet for position sensing and the U 90-degree back cover for flexible mounting. Remember that venting the air supply causes the piston to drift, as the fixed TPU bumpers only decelerate the stroke end rather than locking the rod. Use a pilot-operated check valve if you need to hold a load vertically.
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 MI8X80SU FAQ
The Ø8 mm bore provides a push force of 25.1 N and a pull force of 18.8 N at 0.5 MPa. At 0.7 MPa, push is 35.2 N and pull is 26.4 N. The theoretical maximum force is 5.1 kgf at 1.0 MPa. The air port is M5x0.8.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper pads only decelerate the stroke end; they do not act as a brake. An external rod lock or pilot check valve is required for load holding.
