About the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X100SU
Delivering 25.1 N of push force at 0.5 MPa, the AirTAC MI8X100SU is a compact double-acting round-body mini cylinder built for tight spaces. Its stainless-steel barrel and Ø4 mm rod shrug off mild corrosion, giving it a real edge over painted steel in damp or washdown-prone environments. The 100 mm stroke operates within the 150 mm standard limit for this bore, moving at 30-800 mm/s.
Because the 25.1 N rating is theoretical, plan for a safe working load of about 15 N of actual work at 0.5 MPa. That translates to lifting roughly a 1.3 kg part vertically with a 2:1 safety margin. This SKU includes the -S piston magnet for CMSG, DMSG or EMSG position sensing, and features a U-style 90-degree rear cover for flexible mounting via the ISO 6432 interface.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X100SU Is Used
Micro-Clamp Actuation
Provides 15 N of safe clamping force for securing small electronic components or thin plastic films during high-speed automated assembly.
Lab Dispenser Positioning
Moves a 100 mm stroke to dip or lift small fluid nozzles in diagnostic machines, where the stainless build resists chemical splashes.
Light Part Ejection
Pushes delicate moulded parts weighing under 1.3 kg out of a machining zone without marring the surface, using the fixed TPU bumpers to prevent impact damage.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X100SU the Right Cylinder?
When sizing this 8 mm bore, consider stepping up to the MI12X100 if your application exceeds the 15 N safe working load, as the 12 mm bore provides 56.5 N of push at 0.5 MPa. Since 8 mm is the smallest available MI bore, there is no smaller option for lighter duties. Air enters via an M5x0.8 port, and the male rod features an M4x0.7 thread.
Remember that a standard double-acting cylinder like this will drift if air pressure drops or the valve is centered, as the fixed TPU bumper pads only soften the stroke-end impact rather than locking the rod. For vertical loads that must remain suspended during air loss, add an external pilot-operated check valve or a dedicated rod lock.
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 MI8X100SU FAQ
The 8 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. It uses an M5x0.8 air port and an M4x0.7 male rod thread.
Yes, the -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG or EMSG reed or electronic switches directly to the cylinder body. The U back cover provides a 90-degree mounting interface for standard ISO 6432 mini-cylinder clevis brackets.
