About the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X125SCA
Delivering 25.1 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles precise light-duty tasks. The Ø8 mm bore operates on an M5x0.8 port, while the 125 mm stroke utilizes a CA pivot clevis for articulated rear mounting. Its stainless barrel and rod resist mild corrosion, outperforming painted alternatives in damp environments.
Conforming to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets. The integrated piston magnet (-S) supports CMSG, DMSG, or EMSG switches for position sensing. Plan for roughly 15 N of actual work at 0.5 MPa, which means it lifts about 1.3 kg vertically with a 2:1 safety margin. Fixed TPU bumper pads absorb stroke-end impact without adjustable cushioning.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X125SCA Is Used
Micro-Dispense Dosing
Actuates a micro-valve for adhesive dosing on small electronic PCBs, utilizing the 25.1 N push force to meter precise fluid volumes.
Light-Part Sorting Gate
Pivots a lightweight aluminum deflector gate via the CA clevis to sort small plastic housings on a high-speed packaging line.
Lab Sample Ejector
Pushes small vials out of a testing carousel, where the stainless construction holds up against occasional chemical splashes during washdown.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X125SCA the Right Cylinder?
As the smallest available bore in the series, the MI8X125SCA offers the most compact footprint. If your application requires more power, stepping up to the Ø10 bore increases push force to 39.3 N at 0.5 MPa. The 125 mm stroke approaches the 150 mm maximum for this size, so ensure adequate rod support to prevent side-loading and bending on the 4 mm rod.
Because this is a double-acting cylinder, air drives both extension and retraction. Note that the TPU bumpers only decelerate the stroke end; they do not function as a brake. If the air supply drops, the piston will drift, so add an external rod lock or pilot check valve for suspended loads. The CA rear clevis pairs with LB foot, FA flange, or TC trunnion front options.
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 MI8X125SCA FAQ
At 0.5 MPa, this Ø8 mm bore cylinder provides 25.1 N of push force and 18.8 N of pull force. At 0.7 MPa, push increases to 35.2 N and pull to 26.4 N. The theoretical maximum force is 5.1 kgf at 1.0 MPa. The air port is M5x0.8.
No, the fixed TPU bumper pads only decelerate the piston near the stroke end and do not act as a locking brake. If air is lost or the valve is centered, the piston will drift. For vertical loads, you must install an external rod lock or a pilot-operated check valve.
