About the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X50SU
Delivering 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation with ease. The Ø12 mm bore uses an M5x0.8 air port and an M6x1.0 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. The built-in piston magnet (-S) allows direct mounting of CMSG, DMSG or EMSG switches for position sensing.
For practical sizing, plan for roughly 34 N of real work at 0.5 MPa, which safely lifts about 2.9 kg vertically with a 2:1 margin. The U-style back cover provides a 90-degree port orientation for tight routing. Fixed TPU bumper pads decelerate the piston at stroke end to absorb impact, while the rolled riveted body keeps the unit compact and light.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X50SU Is Used
Electronic Component Sorting
Uses the 56.5 N push force to deflect small PCBs or resistors on a test fixture, relying on the compact 12 mm round body to fit dense conveyor layouts.
Lightweight Parts Ejection
Ejects small plastic moulded parts from a tool, where the 2.9 kg vertical lift capacity easily clears lightweight sprues without stressing the tooling.
Lab Dispenser Actuation
Drives a micro-pump or valve in a damp laboratory setting, benefiting from the stainless-steel construction and 90-degree U back cover for neat tubing runs.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X50SU the Right Cylinder?
When sizing this 12 mm bore, compare it against its neighbours: the smaller Ø8 mm generates 25.1 N of push, whereas the larger Ø16 mm provides 100.5 N at 0.5 MPa. If your application loses air or the valve is centred, the piston will drift, as the TPU bumpers only soften the stroke end rather than locking the load; use an external rod lock or pilot check valve for secure holding. The -S magnet matches CMSG/DMSG/EMSG sensors, and the 50 mm stroke avoids the rod-bending side-load risks seen in longer 250 mm travels.
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 MI12X50SU FAQ
This double-acting cylinder pushes 56.5 N and pulls 42.4 N at 0.5 MPa. At 0.7 MPa, it pushes 79.1 N and pulls 59.4 N. The theoretical maximum force is 11.5 kgf at 1.0 MPa. It features an M5x0.8 air port and a 6 mm piston rod.
Yes, the Ø12 mm bore uses the ISO 6432 mini-cylinder mounting interface, so it drops into standard brackets and clevises. The included -S magnet supports CMSG, DMSG and EMSG switches. Fixed TPU bumpers decelerate the stroke end, but it is not an adjustable air cushion.
