About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X125SCATC
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles 125 mm strokes with ease. The riveted barrel and rod shrug off mild corrosion, making it superior to painted alternatives in damp environments. It includes a built-in magnet for position sensing.
Featuring a 1/8" port and an M8x1.25 male rod thread, the unit relies on fixed TPU bumper pads to decelerate the stroke end. For real-world sizing, plan for a safe working load of about 94 N, which means it lifts roughly 8 kg vertically with a 2:1 margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X125SCATC Is Used
Bottling Line Diverter
Routes plastic containers on a washdown conveyor using the 125 mm stroke and stainless build to resist moisture.
Carton Flap Folder
Folds small cardboard flaps during case packing, utilizing the 157 N push force to crease light materials cleanly.
Textile Loom Tensioner
Adjusts yarn guides dynamically, relying on the TC trunnion to absorb side-play during high-speed weaving.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X125SCATC the Right Cylinder?
This Ø20 bore provides 157 N push at 0.5 MPa, sitting neatly between the Ø16 (100.5 N) and the Ø25 (245.3 N) options. The included TC trunnion mount pairs with the CA pivot back cover to handle angular alignment, while the -S magnet supports CMSG, DMSG, or EMSG switches.
Remember that the TPU bumpers only soften impact; they do not function as a brake. If air pressure drops, the piston will drift, so add an external rod lock or pilot check valve to suspend loads safely.
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 MI16-20 Stainless Steel Mini Cylinder MI20X125SCATC FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N. At 0.7 MPa it pushes 219.8 N and pulls 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa, and the air port is 1/8".
No, the fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. If air is lost, the piston drifts, so you must use an external rod lock or pilot check valve to hold a load.
