About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X20SUTC
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation with ease. The Ø20 mm bore uses a 1/8 inch port and an M8x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments.
The built-in piston magnet supports CMSG, DMSG and EMSG switches for position sensing. Plan for roughly 94 N of actual work at 0.5 MPa, which means it can safely lift about 8 kg vertically with a 2:1 margin. Fixed TPU bumper pads absorb the stroke-end impact, while the ISO 6432 mounting interface ensures compatibility with standard brackets.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X20SUTC Is Used
Package Diverter Gate
Pivots a lightweight routing flap on a packaging line using its 157 N push force and TC trunnion mount to handle repetitive 20 mm strokes.
Small Parts Clamp
Secures aluminum brackets during a light machining operation, utilizing the 8 kg vertical lift capacity and built-in magnet for stroke confirmation.
Lab Dispenser Actuator
Drives a 20 mm dosing stroke for fluid dispensing where the stainless body withstands occasional chemical splashes and wipe-downs.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X20SUTC the Right Cylinder?
When sizing this 20 mm bore, the smaller Ø16 generates 100.5 N of push at 0.5 MPa, whereas stepping up to the Ø25 yields 245.3 N. This model includes a U-type 90-degree rear cover and a TC trunnion mount for pivoting frames. Because it lacks an external rod lock, the piston will drift if air pressure drops, so add a pilot check valve if you need to suspend a load safely. The 20 mm stroke keeps the rod short, minimizing side-load bending risks.
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 MI20X20SUTC FAQ
This Ø20 mm cylinder features a 1/8 inch 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 of 32 kgf at 1.0 MPa.
No, the piston will drift if air pressure is lost. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. For holding a suspended load, install an external rod lock or a pilot-operated check valve.
