About the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X125SCA
Delivering 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles compact automation with ease. The Ø12 mm bore uses an M5×0.8 air port and a Ø6 mm piston rod with an M6×1.0 male thread. Its round-body, riveted construction pairs a stainless barrel and rod to resist mild corrosion in damp or washdown environments better than painted alternatives.
Conforming to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises. The built-in -S magnet supports CMSG, DMSG and EMSG position switches. Plan for a safe working load of roughly 34 N, which means it can lift about 2.9 kg vertically with a 2:1 safety margin. Fixed TPU bumper pads absorb stroke-end impact without adding bulk.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X125SCA Is Used
Electronic Component Sorting
Pushes small PCBs or connectors down a testing lane using a safe 34 N working load, while the CA clevis accommodates slight misalignment.
Pouch Flap Folding
Extends 125 mm to tuck packaging flaps on a filling line, relying on the stainless body to endure humid packing environments.
Lab Sample Diverting
Pivots to route vials into inspection chutes, using the integrated magnet to trigger DMSG reed sensors for precise handoff timing.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X125SCA the Right Cylinder?
When sizing this 125 mm stroke unit, consider the neighbouring bores: the smaller Ø10 generates 39.3 N push at 0.5 MPa, while the larger Ø16 provides 100.5 N. The 125 mm length is well within the 250 mm maximum standard stroke for this bore, but at full extension the Ø6 rod is susceptible to bending if subjected to excessive side loads. The CA rear pivot cover is ideal for clevis mounting, and the -S magnet allows seamless sensor integration.
Note that air pressure alone will not maintain this cylinder's position if the valve is centred or supply is lost; the piston will drift. The fixed TPU pads only decelerate the stroke end rather than acting as a brake. To suspend a load securely, install an external rod lock or a pilot-operated check valve.
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 MI12X125SCA 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 pressure is lost or the valve is centred. The fixed TPU bumper pads only decelerate the stroke end and do not function as a locking brake. Use an external pilot check valve to hold a suspended load.
