About the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X15SCA
Delivering 25.1 N of push force at 0.5 MPa, the AirTAC MI8X15SCA 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 it a real edge over painted alternatives in damp or washdown environments. The riveted construction keeps the body light, while fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning.
Equipped with a built-in magnet (-S), this unit supports CMSG, DMSG and EMSG reed or electronic switches for position sensing. The CA rear pivot cover allows clevis mounting, and the M5x0.8 port matches the Ø8 bore standard. For practical sizing, plan for a safe working load of roughly 15 N (about 60% of the 0.5 MPa rating), which translates to lifting around 1.3 kg vertically with a 2:1 safety margin.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X15SCA Is Used
Micro-Clamp Actuation
Drives small gripper fingers on electronic PCB assembly handlers, utilizing the 15 mm stroke to secure delicate components without overtravel.
Lab Dispenser Pinching
Actuates a pinch valve on automated fluid dispensing lines, where the stainless build resists chemical mist and the 1.3 kg vertical lift capacity is ample.
Small Part Ejection
Pushes lightweight plastic moulded parts out of a sub-1.5 N fixture, relying on the CA clevis to accommodate slight angular misalignment during ejection.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X15SCA the Right Cylinder?
Choosing this 8 mm bore means you are at the smallest end of the MI family, so if the 25.1 N push at 0.5 MPa is insufficient, the next step up is the Ø10 bore providing 39.3 N. The 15 mm stroke is very short, minimizing rod bending risks, but always ensure the load is axially aligned to prevent side-loading wear. Because the base MI uses fixed TPU bumpers rather than an adjustable cushion, it decelerates smoothly but cannot be tuned for high-speed impacts.
The CA back cover provides a pivot point for clevis mounting, and the -S magnet enables standard sensor tracks. Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered; the bumper only softens the end of travel and acts as neither a brake nor a lock. To suspend a load securely during an outage, integrate an external rod lock or a pilot-operated check valve into your circuit.
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 MI8X15SCA FAQ
This Ø8 mm bore cylinder features an M5x0.8 port and a Ø4 mm rod. It generates 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.
Yes, the Ø8 bore utilizes standard ISO 6432 mounting dimensions, allowing it to drop into common mini-cylinder brackets and clevises. Additionally, the -S designation means it has a built-in piston magnet ready for CMSG, DMSG, or EMSG switches.
