About the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X65CA
Generating 25.1 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles light-duty positioning with a 65 mm stroke. The Ø8 mm round-body design features a riveted construction with a CA rear pivot cover, integrating smoothly into clevis mounts. Its stainless barrel and rod resist mild corrosion, outperforming painted alternatives in damp environments.
The integrated fixed TPU bumper pads decelerate the piston at stroke ends without adjustable cushioning. Operating on a 0.15-1.0 MPa pressure range, the M5x0.8 port supplies air efficiently. Plan for roughly 15 N of actual work at 0.5 MPa, which means it can safely lift about 1.3 kg vertically in a 2:1 margin setup.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X65CA Is Used
Micro-Dispenser Actuation
Drives a 1.3 kg adhesive valve head in a packaging line, utilizing the 65 mm stroke to retract the nozzle cleanly between cycles.
Lab Sample Diverting
Pivots a small test-tube routing gate via the CA clevis, relying on the 25.1 N thrust to redirect light plastic carriers.
Small Parts Ejection
Pushes lightweight foam inserts out of a forming die, where the stainless build withstands occasional washdown exposure.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X65CA the Right Cylinder?
When sizing this 8 mm bore, stepping up to the MI12X65 increases push force to 56.5 N at 0.5 MPa for heavier resistance, while the MI8 remains the smallest available AirTAC option for ultra-compact spaces. The CA pivot mount is ideal for articulating mechanisms, but remember the fixed bumpers only soften stroke ends; if air pressure drops, the piston drifts and cannot hold position. To lock a suspended load, add an external rod lock or pilot check valve.
This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG sensors for position feedback. If your application requires end-of-stroke detection, select the -S variant instead.
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 MI8X65CA FAQ
This double-acting cylinder delivers 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 features an M5x0.8 port, a 4 mm rod, and operates at speeds of 30-800 mm/s.
This SKU does not include a magnet, so CMSG, DMSG, or EMSG switches cannot be used. The CA back cover provides a rear pivot point for clevis mounting. It uses standard ISO 6432 mounting dimensions for easy bracket interchange, and fixed TPU bumpers absorb end-of-stroke impact.
