Airtac MI16-20 Stainless Steel Mini Cylinder MI20X25CA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X25CA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 25mm 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 MI20X25CA
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" 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. Built to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets.
The riveted construction keeps the unit light, while fixed TPU bumper pads decelerate the piston at stroke ends. Plan for a safe working load of about 94 N, which easily lifts an 8 kg part vertically with a 2:1 margin. This specific SKU lacks a magnet, so it cannot accept CMSG, DMSG or EMSG position switches without upgrading to the -S variant.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X25CA Is Used
Pivot Arm Actuation
The short 25 mm stroke and rear CA clevis make it ideal for rotating a small sorting flap or pivot arm on a packaging line.
Product Diversion
Provides the 157 N push needed to deflect lightweight cartons on a conveyor belt without overwhelming the mechanism.
Damp Environment Ejection
Stainless steel construction allows safe use in humid washdown zones for ejecting small containers from a filling station.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X25CA the Right Cylinder?
When sizing this actuator, the Ø16 bore below offers 100.5 N of push at 0.5 MPa, whereas the Ø25 bore above steps up to 245.3 N. This 20 mm model hits a solid middle ground for 157 N tasks. The rear CA pivot cover suits articulated clevis mounts, complementing LB foot, FA flange and TC trunnion options. Because this SKU has no -S suffix, it cannot host a magnetic sensor. If air pressure drops, the piston will drift; the bumpers only soften the end of travel rather than locking the load, so add an external rod lock or pilot check valve if you need to hold position.
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 MI20X25CA FAQ
At 0.5 MPa it pushes with 157 N and pulls with 131.9 N. At 0.7 MPa the push is 219.8 N and the pull is 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa. The air port size is 1/8".
Yes, the Ø20 mm body conforms to ISO 6432 mounting dimensions, fitting standard brackets. The rear CA cover provides a pivot point. However, this SKU lacks a magnet, so you cannot mount CMSG, DMSG or EMSG switches on it; you need the -S variant for sensing.
