About the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X25SCA
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 riveted barrel and Ø6 mm rod shrug off mild corrosion, making it superior to painted alternatives in damp processing areas. Its built-in magnet (-S) directly supports CMSG, DMSG and EMSG switches for exact position detection.
Designed around the ISO 6432 mounting interface, the body drops seamlessly into standard mini-cylinder brackets and clevises. The M5x0.8 port feeds air to extend and retract the rod, while fixed TPU bumper pads absorb end-of-stroke impact. For practical sizing, plan for roughly 34 N of usable work at 0.5 MPa, which translates to safely lifting about 2.9 kg vertically against gravity.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X25SCA Is Used
Electronic Component Sorting
Pushes small PCBs or microchips into testing fixtures using a reliable 56.5 N force, where the stainless body prevents corrosion from flux residues.
Packaging Diverter Arm
Actuates a lightweight routing gate along a conveyor line, with the CA clevis allowing the pivoting motion needed to redirect small cartons.
Lab Sample Ejection
Ejects vials from a testing carousel; the 25 mm stroke and integrated magnet provide precise position confirmation via DMSG reed switches.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X25SCA the Right Cylinder?
When sizing this 12 mm bore, compare it against its neighbours: a 10 mm bore yields 39.3 N of push at 0.5 MPa, whereas stepping up to a 16 mm bore provides 100.5 N. This positions the 25 mm stroke unit perfectly for tight, low-force positioning tasks. The included CA back cover supplies a rear pivot point for clevis mounting, and the integrated magnet enables solid state sensing.
Remember that a standard double-acting cylinder drifts if air pressure drops or the valve is centred, as the TPU bumpers only decelerate the stroke end rather than locking the load. To suspend a vertical weight safely, incorporate 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 MI12X25SCA FAQ
This 12 mm bore cylinder features an M5x0.8 air port and a Ø6 mm rod. It generates 56.5 N push and 42.4 N pull at 0.5 MPa, increasing to 79.1 N push and 59.4 N pull at 0.7 MPa. The theoretical maximum force is 11.5 kgf at 1.0 MPa.
It uses a CA rear pivot cover for clevis mounting and conforms to ISO 6432 dimensions. The fixed TPU bumpers only decelerate the piston near the stroke end; they do not act as a brake. If air is lost, the rod will drift, so an external rod lock or pilot check valve is required to hold a suspended load.
