About the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X30CA
Delivering 25.1 N of push force at 0.5 MPa, the AirTAC MI8X30CA 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 a real edge over painted steel in damp or washdown-prone environments. The riveted construction keeps the unit light, while fixed TPU bumper pads absorb the impact at stroke end. This CA back-cover version features a rear pivot/clevis mount for articulated linkages.
Because the 8 mm bore uses an M5x0.8 port and an M4x0.7 male rod thread, it integrates seamlessly into miniature pneumatic setups. Operating at 0.15-1.0 MPa, it conforms to ISO 6432 mounting dimensions for straightforward bracket matching. Plan for roughly 15 N of actual work at 0.5 MPa to ensure reliable operation, which translates to lifting about 1.3 kg vertically with a 2:1 safety margin. Note that this specific SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X30CA Is Used
Micro-Clamp Actuation
Drives small assembly tooling grippers, using the 25.1 N output to hold light plastic or thin-metal components during a precise machining or joining process.
Lab Dispenser Routing
Pivots fluid nozzle brackets via the CA clevis in compact laboratory automation, where the stainless body withstands occasional chemical splashes.
Small Part Ejection
Pushes delicate electronics parts out of test fixtures, relying on the fixed TPU pads to soften the 30 mm stroke end without damaging components.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X30CA the Right Cylinder?
When sizing this 8 mm bore, stepping up to the Ø10 variant raises the push force to 39.3 N at 0.5 MPa if your payload exceeds the safe 15 N working load. As the smallest available MI option, there is no smaller bore to drop down to for lighter duties. The 30 mm stroke is well within the 150 mm standard maximum, keeping the rod rigid and minimizing side-load bending. Remember that a plain cylinder drifts when air is lost or a valve is centered; the TPU bumpers only decelerate the stroke end and act as neither a lock nor a brake. For suspended loads, specify 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 MI8X30CA FAQ
This double-acting cylinder 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. It uses an M5x0.8 air port and features a Ø4 mm piston rod with an M4x0.7 male thread.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG or EMSG switches. You would need the -S variant for position sensing. It does, however, use standard ISO 6432 mounting dimensions and includes a CA rear pivot cover for clevis attachment.
