Airtac MI16-20 Stainless Steel Mini Cylinder MI20X120SCA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X120SCA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 120mm stroke, 1/8" 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 MI16-20 Stainless Steel Mini Cylinder MI20X120SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles robust linear tasks. The riveted barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. Its 120 mm stroke operates at 30-800 mm/s, decelerating cleanly at the ends via fixed TPU bumper pads.
Conforming to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises. The built-in piston magnet allows CMSG, DMSG or EMSG switches to track position, while the 1/8" port feeds air efficiently. For practical sizing, plan for roughly 94 N of actual work at 0.5 MPa, which translates to lifting about 8 kg vertically with a safe 2:1 margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X120SCA Is Used
Package Diverter Gate
Pushes light cardboard cartons on a packaging line using its 120 mm stroke, relying on the stainless body to withstand humid packing-room washdowns.
Small Press Ejection
Provides a reliable 157 N push at 0.5 MPa to knock stamped small metal parts out of a die, absorbing end-of-stroke impact with fixed TPU pads.
Pallet Labelling Arm
Swings via its CA pivot clevis to press an applicator head against pallets, lifting around 8 kg of tooling vertically with a safe 2:1 margin.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X120SCA the Right Cylinder?
When sizing this 20 mm bore, compare it against its neighbours: a 16 mm bore yields 100.5 N push at 0.5 MPa, while stepping up to a 25 mm bore provides 245.3 N. This model includes a CA rear pivot cover for clevis mounting and a built-in magnet for sensors. If your mechanism requires the rod to stay put during air loss or valve centring, note that the piston will drift; add an external rod lock or pilot check valve for secure load holding. For the 120 mm stroke, ensure the front mount aligns the rod to prevent side-load bending.
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 MI20X120SCA FAQ
At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it yields 219.8 N push and 184.7 N pull, with a theoretical max of 32 kgf at 1.0 MPa. The air port is 1/8" and the male rod thread is M8x1.25.
No, a standard double-acting cylinder drifts when 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. You must fit an external rod lock or pilot-operated check valve to hold a load safely.
