About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X30U
Generating 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles short 30 mm strokes with efficiency. The riveted construction and 1/8" port keep the unit compact while resisting mild corrosion in damp environments. Fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning.
For practical sizing, plan for a working load of roughly 94 N, which equates to lifting about 8 kg vertically with a safe 2:1 margin. This SKU lacks the -S magnet, meaning it cannot host CMSG, DMSG or EMSG sensors for position feedback. The U back cover provides a 90-degree port and mounting orientation for tight spaces.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X30U Is Used
Package Deflector
Pushes lightweight cardboard cartons on a packaging line using a quick 30 mm stroke, leveraging the 157 N push force to divert items without damaging them.
Clamp Actuator
Secures small aluminium brackets in a milling fixture, applying a safe working load of 94 N to hold the part firmly against cutting vibrations.
Bin Gate Trigger
Opens and closes a small hopper flap for parts sorting, utilizing the 90-degree U cover to mount flush against the machine frame in tight quarters.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X30U the Right Cylinder?
When sizing this 20 mm bore, the smaller MI16 yields 100.5 N of push at 0.5 MPa, whereas stepping up to the MI25 provides 245.3 N. If your application requires position detection, select the MI20X30U-S instead, as this base model cannot accept magnetic switches. The 30 mm stroke is well within the 500 mm maximum, keeping rod bending stress minimal.
Because the U-type rear cover sets a fixed 90-degree orientation, ensure your bracket aligns with this geometry. Remember that venting air or centering the valve causes the piston to drift; the bumpers only decelerate the end of travel. To suspend a load securely during air loss, install an external pilot check valve or rod lock.
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 MI20X30U FAQ
This 20 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, this specific SKU does not include a magnet. You must choose the -S variant to use CMSG, DMSG or EMSG switches. Additionally, the stainless build meets ISO 6432 mounting dimensions for standard brackets, and fixed TPU bumpers handle end deceleration.
