About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X30SU
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 features a 1/8" 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 settings. The riveted construction keeps the body light, while fixed TPU bumper pads absorb the impact at stroke extremes.
Equipped with a piston magnet, this unit supports CMSG, DMSG, and EMSG reed or electronic switches for position sensing. It conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets and clevises. For practical sizing, plan for a safe working load of roughly 94 N, which means it can lift about 8 kg vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X30SU Is Used
Package Diverter Gate
Actuates a short-stroke flap to sort small to medium parcels on a packaging line, utilising the 157 N push force to overcome guide friction.
Textile Loom Tensioner
Maintains precise yarn tension in a humid manufacturing environment, relying on the stainless steel rod to resist mild corrosion.
Small Component Ejector
Kicks machined plastic parts out of a moulding area using the 30 mm stroke, with the 90-degree U cover allowing a compact side-mount footprint.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X30SU the Right Cylinder?
When sizing this 30 mm stroke actuator, compare it against adjacent bores: the smaller Ø16 generates 100.5 N of push at 0.5 MPa, while the larger Ø25 provides 245.3 N. Choose the Ø20 when your application demands that middle-ground force. The U suffix denotes a 90-degree rear cover, altering your port orientation and pivot geometry for tight layouts. Because the -S magnet is present, you can directly mount position sensors.
Remember that a standard double-acting cylinder drifts if air pressure drops or the valve is centred, as the TPU bumpers only decelerate the end-of-stroke impact rather than locking the rod. To suspend a load safely during an air loss event, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 MI20X30SU FAQ
This Ø20 mm bore cylinder features a 1/8" 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 or the valve is centred. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. To hold a vertical load, you must add an external rod lock or pilot check valve.
