Airtac MI8~12 Stainless Steel Mini Cylinder MI8X35CA
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI8X35CA is a genuine double acting round-body mini air cylinder with a Ø8mm bore and 35mm 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 MI8X35CA
Generating 25.1 N of push force at 0.5 MPa, this compact stainless-steel mini cylinder handles light-duty actuation with ease. The Ø8 mm bore uses an M5x0.8 air port and an M4x0.7 male rod thread, operating smoothly across a 30-800 mm/s speed range. Its riveted round-body construction shrinks the footprint while resisting mild corrosion in damp environments.
Because the 35 mm stroke is short, fixed TPU bumper pads adequately soften the impact at both ends without requiring adjustable cushioning. For practical sizing, plan for a real work load of about 15 N, which lets you lift a 1.3 kg part vertically with a safe 2:1 margin. This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG or EMSG position switches.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X35CA Is Used
Gripper Jaw Actuation
Provides the 15 N safe working force needed to open and close delicate pneumatic gripper jaws on small robotic pick-and-place handlers.
Lab Dispenser Valve
Taps the 35 mm stroke to push a metering valve for low-viscosity fluids, benefiting from the stainless build during washdown cycles.
Micro-Clamp Mechanism
Secures tiny electronic components during soldering, using the CA clevis to pivot the clamping arm precisely into place.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X35CA the Right Cylinder?
As the smallest bore in the MI family, there is no smaller option if 25.1 N at 0.5 MPa proves insufficient; stepping up to the Ø10 bore provides 39.3 N of push force. The built-in CA rear pivot cover suits clevis mounting for pivoting linkages. Remember that the TPU bumpers only decelerate the stroke end; if air pressure drops, the piston drifts, so fit an external pilot check valve to suspend a vertical load.
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 MI8X35CA FAQ
At 0.5 MPa it provides 25.1 N push and 18.8 N pull; at 0.7 MPa it yields 35.2 N push and 26.4 N pull, with a theoretical maximum of 5.1 kgf at 1.0 MPa. The air port is M5x0.8.
This SKU lacks the -S magnet, so it cannot accept CMSG, DMSG or EMSG switches. It does conform to ISO 6432 mounting dimensions for Ø8, dropping into standard mini-cylinder brackets, and features a CA pivot clevis.
