About the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X120CA
Delivering 25.1 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles compact automation tasks with a 120 mm stroke. The Ø8 mm round-body barrel and Ø4 mm piston rod are built from stainless steel, resisting mild corrosion and washdowns better than painted alternatives. Riveted construction keeps the envelope small, while fixed TPU bumper pads absorb the impact at stroke ends.
Operating at 30-800 mm/s on an M5x0.8 port, it integrates easily using the ISO 6432 mounting dimensions. Plan for roughly 15 N of actual work at 0.5 MPa to ensure reliable cycling. This translates to lifting about 1.3 kg vertically with a 2:1 safety margin. The rear CA pivot clevis suits articulated mechanisms, though note this SKU lacks a magnet for position sensing.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X120CA Is Used
Lightweight Pick-and-Place
Moves small electronic components on a pivoting arm, utilising the CA clevis to maintain alignment during the 120 mm extension.
Lab Dispenser Actuation
Drives a micro-valve for chemical dosing where the stainless body resists humid environments and mild chemical splashes.
Small Part Ejection
Pushes lightweight plastic mouldings out of a fixture, comfortably handling the 15 N safe working load at 0.5 MPa.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X120CA the Right Cylinder?
When sizing this Ø8 bore, stepping up to the Ø12 bore increases push force to 56.5 N at 0.5 MPa for heavier duties, while there is no smaller AirTAC MI option below 8 mm. The 120 mm stroke is well within the 150 mm standard maximum, keeping the rod bending risk low. Because this is a plain double-acting cylinder, the piston will drift if air pressure drops or the valve is centred; the bumpers only decelerate the end of travel and do not act as a brake. For suspended or gravity-loaded applications, install an external pilot check valve or rod lock. To add CMSG, DMSG or EMSG reed switches, select the -S magnet variant instead of this base model.
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 MI8X120CA FAQ
This Ø8 mm bore cylinder features an M5x0.8 port and a Ø4 mm rod. It generates 25.1 N push and 18.8 N pull at 0.5 MPa, 35.2 N push and 26.4 N pull at 0.7 MPa, with a theoretical maximum force of 5.1 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so CMSG, DMSG or EMSG switches cannot be used. You must select the -S variant (with magnet) to enable magnetic sensing. It uses the ISO 6432 mounting interface and includes a CA rear pivot clevis.
