About the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X250SCALB
Delivering 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 250 mm stroke with ease. The Ø12 mm bore operates on an M5x0.8 port, while the integrated piston magnet allows direct mounting of CMSG, DMSG, or EMSG sensors for position detection. Its riveted stainless barrel and rod naturally resist mild corrosion, offering a distinct advantage over painted alternatives in damp or washdown environments.
Because it adheres to ISO 6432 mounting dimensions, this unit drops seamlessly into standard mini-cylinder brackets and clevises. Fixed TPU bumper pads absorb the impact at stroke extremes, smoothly decelerating the piston without the complexity of adjustable cushioning. For practical sizing, plan for a safe working load of about 34 N, which lets you lift roughly 2.9 kg vertically with a safe 2:1 margin.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X250SCALB Is Used
Textile Loom Yarn Guide
Shifts a yarn guide carriage across a 250 mm path, utilizing the 56.5 N push force and stainless build to withstand humid textile manufacturing environments.
Small Carton Flap Folder
Employs the CA clevis to pivot a folding arm, tucking packaging flaps on a compact filling line where the 2.9 kg vertical lift capacity easily handles light cardboard.
Lab Sample Dispenser
Actuates a 250 mm dispensing nozzle over multiple test tubes, relying on the integrated -S magnet and DMSG switches for precise fluid volume routing.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X250SCALB the Right Cylinder?
Choosing this 250 mm stroke configuration means verifying side-load risks, as longer rods are more susceptible to bending under off-center forces. If your task requires less energy, the smaller Ø10 bore generates 39.3 N of push at 0.5 MPa; conversely, stepping up to the Ø16 bore yields 100.5 N for heavier cycles. The included LB foot mount combined with the CA rear clevis provides flexible anchoring options for your frame.
Remember that standard double-acting cylinders drift when air pressure drops or the valve is centered, as the fixed bumpers only soften the end-of-stroke impact and act as no brake. To suspend a load securely during an outage, integrate an external rod lock or a pilot-operated check valve into your pneumatic 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 MI12X250SCALB FAQ
This Ø12 mm bore cylinder features an M5x0.8 port and a male M6x1.0 rod thread. It generates a push force of 56.5 N and a pull force of 42.4 N at 0.5 MPa. At 0.7 MPa, push increases to 79.1 N and pull to 59.4 N. The theoretical maximum force is 11.5 kgf at 1.0 MPa.
No, the fixed TPU bumper pads only decelerate the piston near the stroke end and do not function as a locking brake. If air is lost or the valve is centered, the rod will drift. To maintain a vertical load safely, you must add an external rod lock or a pilot-operated check valve.
