About the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X50SCASDB
Delivering 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact actuation with precision. The Ø12 mm bore uses an M5x0.8 air port and a Ø6 mm piston rod with an M6x1.0 male thread. Built-in fixed TPU bumper pads decelerate the piston at stroke ends, while the riveted stainless construction resists mild corrosion in damp environments.
Because it carries an internal magnet, this -S variant supports CMSG, DMSG and EMSG position switches. For real-world sizing, plan for a safe working load of about 34 N at 0.5 MPa. This equates to lifting roughly 2.9 kg vertically with a 2:1 safety margin, letting you match the cylinder directly to your part weights.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X50SCASDB Is Used
Small Part Ejection
Uses the 56.5 N push force to knock lightweight plastic mouldings off an injection press conveyor without damaging the part surface.
Guidance Diverter
Pivots via the CA clevis and SDB block to push a mechanical gate, routing small electronic components down the correct machining track.
Lab Sample Handling
The stainless steel barrel withstands wipe-down chemicals in laboratory automation while the 50 mm stroke moves sample trays precisely.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X50SCASDB the Right Cylinder?
When sizing this 12 mm bore, compare it against the smaller Ø8 bore (25.1 N push @0.5 MPa) for lighter tasks, or step up to the Ø16 bore (100.5 N push @0.5 MPa) if you need significantly more thrust. This SKU includes a CA rear pivot clevis and an SDB pivot-block for articulated mounting. Note that a standard cylinder drifts if air pressure drops or the valve is centered; the bumpers only soften the stroke end rather than locking the rod, so add an external rod lock or pilot check valve for held loads.
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 MI12X50SCASDB FAQ
This 12 mm bore cylinder features an M5x0.8 port and generates 56.5 N push / 42.4 N pull at 0.5 MPa, and 79.1 N push / 59.4 N pull at 0.7 MPa. The theoretical maximum force is 11.5 kgf at 1.0 MPa.
Yes, the -S suffix means it has a built-in magnet for CMSG, DMSG or EMSG switches. It uses standard ISO 6432 mounting dimensions, includes a CA rear clevis cover, and is paired with an SDB pivot-block for articulated installations.
