About the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X150SCALB
Generating 25.1 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles precise 150 mm linear movements. The riveted round-body construction pairs a corrosion-resistant barrel and piston rod, performing reliably in damp or washdown environments where painted alternatives degrade. An integrated piston magnet allows direct mounting of CMSG, DMSG or EMSG sensors for position confirmation.
Operating at the maximum standard stroke limit for an 8 mm bore, it provides a safe working load of about 15 N, which translates to lifting roughly 1.3 kg vertically with a 2:1 safety margin. The M5x0.8 port supplies air to both extend and retract the 4 mm rod. Fixed TPU bumper pads absorb end-of-stroke impact, and the ISO 6432 mounting dimensions ensure compatibility with standard mini-cylinder brackets.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X150SCALB Is Used
Micro-Clamp Actuation
Drives small pneumatic clamps in electronics assembly fixtures, utilizing the 25.1 N push force to secure delicate PCBs without causing structural damage.
Lab Dispenser Positioning
Moves lightweight fluid dispensing nozzles across a 150 mm range in automated laboratory equipment, benefiting from the stainless build during chemical wipe-downs.
Small Part Ejection
Pushes miniature plastic components out of molding machines, using the integrated magnet and DMSG sensor to confirm ejection before the mold closes.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X150SCALB the Right Cylinder?
Choosing this 8 mm bore makes sense when a 150 mm stroke is required at the lower end of the AirTAC range, as there is no smaller standard MI size. If an application demands greater thrust, stepping up to the 10 mm bore raises the push force to 39.3 N at 0.5 MPa. Because this unit reaches the maximum standard stroke for its size, verify rod support to avoid side-loading and bending on the 4 mm rod. The included LB foot bracket secures the body, while the CA rear pivot cover offers alternate clevis mounting.
This configuration includes the -S magnet for switch sensing, but remember a standard cylinder drifts if air pressure drops or the valve is centred. The TPU bumpers only decelerate the stroke end rather than locking the load. To hold a vertical position securely, add an external rod lock or a pilot-operated check valve to the 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 MI8X150SCALB FAQ
At 0.5 MPa, the push force is 25.1 N and the pull force is 18.8 N. 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. The air port is M5x0.8.
No, the piston will drift if air pressure drops or the directional valve is centred. The fixed TPU bumper pads only decelerate the rod near the stroke end and do not function as a brake. Use an external rod lock or pilot check valve for load holding.
