Airtac MI8~12 Stainless Steel Mini Cylinder MI12X50SCALB
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI12X50SCALB is a genuine double acting round-body mini air cylinder with a Ø12mm 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 MI12X50SCALB
Delivering 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles light-duty positioning with reliability. The riveted round-body construction pairs a corrosion-resistant barrel and Ø6 mm rod, making it well-suited for damp or washdown environments where painted alternatives degrade. Because it follows ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises.
Air enters through an M5×0.8 port to drive the piston across the 50 mm stroke, while fixed TPU bumper pads absorb end-of-travel impacts. The built-in -S magnet supports CMSG, DMSG and EMSG position switches. For practical sizing, plan for roughly 34 N of actual work at 0.5 MPa; vertically, it lifts about 2.9 kg with a 2:1 safety margin.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X50SCALB Is Used
Small Part Ejection
Pushes lightweight plastic mouldings out of an injection press chute using a safe 34 N working load at 0.5 MPa.
Lab Dispenser Actuation
Stainless construction withstands chemical splashes while accurately stroking 50 mm to press a fluid pump head.
Package Diverting
Deploys a lightweight routing flap on a packaging line, using the LB foot mount to secure the diverter mechanism.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X50SCALB the Right Cylinder?
When sizing this 12 mm bore, stepping down to an Ø8 unit drops the 0.5 MPa push force to 25.1 N, whereas moving up to a Ø16 bore increases it to 100.5 N. This SKU includes an LB foot mount for rigid base anchoring and a CA rear pivot cover for clevis attachments. The -S magnet enables electronic or reed sensor tracking along the body.
If air pressure drops or the directional valve centres, the piston drifts and cannot sustain a load; the TPU bumpers only soften the stroke end rather than locking the rod. For suspended loads that must hold position, add an external rod lock or a pilot-operated check valve. On this 50 mm stroke, keep the rod guided to prevent side-loading and premature seal wear.
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 MI12X50SCALB FAQ
At 0.5 MPa it provides 56.5 N push and 42.4 N pull. At 0.7 MPa it provides 79.1 N push and 59.4 N pull. The theoretical maximum force is 11.5 kgf at 1.0 MPa. The air port is M5×0.8.
No, the piston will drift if air is lost or the valve is centred. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. Use an external rod lock or pilot check valve to hold suspended loads.
