About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X30SCATC
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles short 30 mm strokes with precision. The riveted barrel and rod resist mild corrosion, making it superior to painted alternatives in damp environments. It uses the ISO 6432 mounting interface, dropping easily into standard mini-cylinder brackets.
Equipped with a 1/8" air port and an M8x1.25 male rod thread, it integrates seamlessly into existing pneumatic setups. The built-in -S magnet supports CMSG, DMSG and EMSG sensors for position detection. Fixed TPU bumper pads absorb end-of-stroke impact, while the TC trunnion and CA pivot cover supply flexible mounting. Plan for roughly 94 N of actual work at 0.5 MPa, which safely lifts about 8 kg vertically.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X30SCATC Is Used
Package Diverting Gate
Actuates a short-stroke routing flap on a packaging conveyor, utilizing the 157 N push force to redirect light cardboard cartons efficiently.
Component Clamping Jig
Secures aluminum housings during a CNC drilling operation, where the 8 kg vertical lift capacity provides ample holding pressure for the fixture.
Bin Lid Automation
Pivots a stainless-steel access hatch on a material hopper using the CA clevis, with the -S magnet confirming lid closure for the safety logic.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X30SCATC the Right Cylinder?
When sizing this 20 mm bore, stepping down to the Ø16 variant lowers the output to 100.5 N push at 0.5 MPa, whereas moving up to the Ø25 bore increases it to 245.3 N. This model includes a TC trunnion and a CA rear pivot cover, so ensure your mechanical layout accommodates these specific attachment styles. The -S magnet is essential if your control system requires CMSG, DMSG or EMSG position switches.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the fixed TPU pads only decelerate the stroke end rather than locking the rod. To suspend a load securely during an outage, install an external rod lock or a pilot-operated check valve. For the 30 mm stroke, side-load stress on the 8 mm rod is minimal, but always verify alignment to prevent 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 MI16-20 Stainless Steel Mini Cylinder MI20X30SCATC FAQ
This 20 mm bore cylinder features a 1/8" air port and an M8x1.25 male rod thread. It generates 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum force of 32 kgf at 1.0 MPa.
No, the fixed TPU bumper pads only decelerate the piston near the stroke end and do not act as a brake. If air is lost or the valve is centered, the rod will drift; use an external rod lock or pilot check valve to maintain vertical position. The included -S magnet works with CMSG, DMSG and EMSG sensors for end-of-stroke confirmation.
