Airtac MI8~12 Stainless Steel Mini Cylinder MI8X200SU
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI8X200SU is a genuine double acting round-body mini air cylinder with a Ø8mm bore and 200mm 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 MI8X200SU
Generating 25.1 N of push force at 0.5 MPa, this Ø8 mm bore actuator is built for light-duty automation. The 200 mm travel distance exceeds the 150 mm standard limit for this size, making it a non-standard, made-to-order unit. Its stainless-steel round barrel and piston rod shrug off mild corrosion, giving it a real edge over painted-steel alternatives in damp or washdown environments. A 90-degree U back cover keeps the M5x0.8 port orientation tidy for tight routing.
Because the piston only pushes with roughly 25 Newtons, plan for a safe working load of about 15 N to ensure reliable cycling. In vertical lifting scenarios, that equates to hoisting roughly 1.3 kg with a 2:1 safety margin. The integrated -S magnet supports CMSG, DMSG and EMSG switches for position sensing, while fixed TPU bumper pads absorb the impact at stroke ends without acting as an adjustable cushion.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X200SU Is Used
Lab Sample Dispensing
Uses the 25.1 N push force to accurately actuate tiny fluid valves, with the stainless build resisting chemical splashes during testing routines.
PCB Component Pusher
Employs the 200 mm non-standard stroke to clear delicate circuit boards on a conveyor, relying on the U cover for compact 90-degree mounting.
Micro-Clamp Actuation
Leverages the 1.3 kg vertical lift capacity to raise and lower small electronic parts, using the -S magnet to trigger DMSG sensors for precise positioning.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X200SU the Right Cylinder?
If the 25.1 N push at 0.5 MPa proves insufficient, stepping up to the Ø10 bore yields 39.3 N; there is no smaller AirTAC MI option below 8 mm. When sizing this 200 mm travel, note that it is a non-standard length requiring special order. For side-load resilience on such a long, slender 4 mm rod, ensure rigid guiding to prevent rod bending. The U-style rear cover and ISO 6432 mounting dimensions allow straightforward integration into standard mini-cylinder clevises.
Remember that this double-acting cylinder will drift if air pressure drops or the valve is centred—the TPU bumpers only decelerate the stroke end and do not function as a locking brake. To suspend a load safely mid-stroke, fit 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 MI8X200SU FAQ
This Ø8 mm bore cylinder features an M5x0.8 port and a 4 mm rod. It generates 25.1 N push and 18.8 N pull at 0.5 MPa, or 35.2 N push and 26.4 N pull at 0.7 MPa. The theoretical maximum force is 5.1 kgf at 1.0 MPa.
Yes, the Ø8 bore uses the ISO 6432 mounting interface, so it drops into standard mini-cylinder brackets and clevises. The -S suffix indicates a built-in magnet for CMSG, DMSG or EMSG electronic switches, and the rear U cover provides a 90-degree port orientation.
