About the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X90CA
Delivering 25.1 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation tasks with ease. The Ø8 mm bore features an M5x0.8 port and a 90 mm stroke, utilizing a CA rear pivot cover for clevis mounting. Its riveted stainless barrel and rod resist mild corrosion, outperforming painted alternatives in damp environments. The body conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets.
Because the rod extends and retracts via air pressure, you can plan for roughly 15 N of actual work at 0.5 MPa. This equates to lifting about 1.3 kg vertically with a safe 2:1 margin. Fixed TPU bumper pads absorb stroke-end impact, though this SKU lacks a magnet and cannot support CMSG, DMSG, or EMSG sensors.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X90CA Is Used
Micro-Clip Insertion
Pushes small wire clips into PCB assemblies using the 25.1 N output, with the CA clevis allowing the body to pivot and absorb minor alignment shifts.
Lab Dispenser Actuation
Drives a tiny pump head for chemical dosing where the stainless steel construction prevents mild corrosion from ambient fumes.
Small Part Ejection
Kicks lightweight plastic moulded parts out of a machining zone, lifting components under 1.3 kg safely at 0.5 MPa.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X90CA the Right Cylinder?
When sizing this 8 mm bore, note that it is the smallest available in the MI series, providing 18.8 N pull at 0.5 MPa. If your application requires more power, the next size up is the Ø12 bore, which outputs 56.5 N push at 0.5 MPa. The 90 mm stroke is well within the 150 mm standard maximum, keeping the unit compact. For pivoting loads, the built-in CA clevis is ideal, but remember that a standard cylinder drifts if air pressure is lost; add an external rod lock or pilot check valve if you need to hold a load securely.
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 MI8X90CA FAQ
At 0.5 MPa it provides 25.1 N push and 18.8 N pull. At 0.7 MPa it provides 35.2 N push and 26.4 N pull. The theoretical maximum force is 5.1 kgf at 1.0 MPa. The air port is M5x0.8.
No, this specific SKU does not include a magnet, so it cannot support CMSG, DMSG, or EMSG switches. You would need the -S variant for sensor compatibility. It uses fixed TPU bumper pads for end-of-stroke deceleration, not an adjustable air cushion.
