Airtac MI8~12 Stainless Steel Mini Cylinder MI10X50U
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI10X50U is a genuine double acting round-body mini air cylinder with a Ø10mm bore and 50mm stroke, M5×0.8 air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MI8~12 Stainless Steel Mini Cylinder MI10X50U
Delivering 39.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles light actuation with precision. The riveted barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp processing areas. Its 50 mm stroke operates at 30-800 mm/s, and the integrated fixed TPU bumper pads quietly absorb end-of-travel impacts without requiring manual adjustment.
Because the thrust is modest, plan for a safe working load of about 24 N rather than the absolute maximum. This translates to lifting roughly 2 kg vertically with a sensible 2:1 safety margin. The U-type back cover provides a 90-degree port orientation for tight routing, and the M5x0.8 air port keeps the pneumatic footprint minimal. Note that this specific SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors without upgrading to an -S variant.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI10X50U Is Used
PCB Ejector Pins
Provides the exact 39.3 N push at 0.5 MPa needed to gently pop bare circuit boards from test fixtures without marring the surface.
Small Parts Diverter
Uses the 90-degree U cover to mount cleanly above a belt, stroking 50 mm to push lightweight plastic caps into a secondary packaging lane.
Lab Sample Ejection
The stainless build withstands daily wipe-downs and mild cleaning chemicals in laboratory automation, safely ejecting 2 kg sample trays.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI10X50U the Right Cylinder?
When sizing this 10 mm bore, compare it directly against its neighbours: the smaller Ø8 generates 25.1 N of push at 0.5 MPa, while the larger Ø12 provides 56.5 N. Choose this model when your payload sits comfortably under that 24 N safe working threshold. The 50 mm stroke is well within the 200 mm maximum standard limit, keeping the rod highly resistant to bending. The ISO 6432 mounting interface ensures it drops directly into standard mini-cylinder brackets and clevises.
Remember that a standard double-acting cylinder like this will drift if air pressure drops or the valve is centred. The fixed bumpers only decelerate the piston near the stroke end; they do not act as a brake. If your application requires the rod to stay firmly in place under load during an air loss event, you must 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 MI10X50U FAQ
This 10 mm bore cylinder generates 39.3 N push and 33 N pull at 0.5 MPa, increasing to 55 N push and 46.1 N pull at 0.7 MPa, with a theoretical maximum of 8 kgf at 1.0 MPa. It uses an M5x0.8 pneumatic port and features a male M4x0.7 rod thread.
No, this specific SKU does not include a piston magnet, so it cannot accept CMSG, DMSG or EMSG switches. You would need the -S magnet variant for position sensing. It uses the ISO 6432 mounting interface for standard brackets and relies on fixed TPU bumper pads for end-of-stroke deceleration.
