About the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X100SCA
Delivering 25.1 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles compact actuation with a 100 mm stroke. The Ø8 mm round-body barrel and Ø4 mm piston rod are riveted and rolled, offering mild corrosion resistance that outlasts painted aluminium in damp or washdown settings. Because this SKU includes the -S magnet, it directly supports CMSG, DMSG and EMSG reed or electronic switches for position sensing.
Air extends and retracts the rod through an M5x0.8 port, while fixed TPU bumper pads absorb the impact at each stroke end. For practical sizing, plan for roughly 15 N of real work at 0.5 MPa, which translates to lifting about 1.3 kg vertically with a 2:1 safety margin. The built-in CA rear pivot clevis simplifies angular mounting, and the body conforms to ISO 6432 mini-cylinder mounting dimensions for standard bracket interchangeability.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X100SCA Is Used
Micro-Clamp Actuation
Drives small pneumatic clamps in PCB routing machines, using the 25.1 N push force to secure delicate panels during milling.
Lab Dispenser Positioning
Moves a 100 mm dispensing nozzle in automated fluid-fill stations, relying on the stainless body to resist mild chemical splashes.
Lightweight Part Ejection
Pushes tiny moulded plastic parts out of a machining fixture, lifting components under 1.3 kg via the CA pivot clevis.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X100SCA the Right Cylinder?
When sizing this 8 mm bore, stepping up to the Ø10 bore raises the 0.5 MPa push force to 39.3 N, whereas the Ø8 is the smallest available AirTAC MI option. The 100 mm stroke is well within the 150 mm standard limit for this bore, though at full extension the slender Ø4 mm rod is vulnerable to side-loading, so keep the load guided and axial. The included -S magnet enables CMSG, DMSG and EMSG sensors without modification.
Remember that a standard double-acting cylinder drifts if air pressure drops or the valve is centred; the TPU bumpers only decelerate the stroke end and do not act as a brake. To suspend a load safely during an air loss event, fit 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 MI8X100SCA FAQ
This double-acting cylinder uses an M5x0.8 port and generates 25.1 N push / 18.8 N pull at 0.5 MPa, and 35.2 N push / 26.4 N pull at 0.7 MPa. Its theoretical maximum force is 5.1 kgf at 1.0 MPa.
Yes, the -S suffix denotes a built-in piston magnet compatible with CMSG, DMSG and EMSG switches. It uses fixed TPU bumper pads to decelerate at the stroke end, but for adjustable air cushioning you would need the MIC variant.
