Airtac MI16-20 Stainless Steel Mini Cylinder MI20X25SCA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X25SCA 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 MI20X25SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles short 25 mm strokes with precision. The integrated piston magnet allows direct mounting of CMSG, DMSG or EMSG reed switches for end-of-stroke confirmation. Its 1/8" port feeds the bore efficiently, while the fixed TPU bumper pads absorb the impact at stroke extremes without requiring manual adjustment.
Because the Ø20 mm body follows ISO 6432 mounting dimensions, it drops seamlessly into standard mini-cylinder brackets and clevises. The stainless barrel and rod resist mild corrosion, making it superior to painted alternatives in damp or washdown environments. For practical sizing, plan for roughly 94 N of usable work at 0.5 MPa, which means it can comfortably lift an 8 kg part vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X25SCA Is Used
Gate Diverter Arms
Actuates short-stroke sorting flaps on packaging conveyors, using the 157 N push force to redirect small cartons reliably.
Product Reject Pushers
Ejects misaligned items from a moving belt, where the 25 mm stroke and CA pivot mount accommodate slight angular misalignment.
Pallet Stopper Pins
Deploys a short 25 mm stop block to halt pallets at a workstation, benefiting from the stainless build in humid warehouse environments.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X25SCA the Right Cylinder?
When sizing this actuator, compare it against its neighbours: a Ø16 bore provides 100.5 N of push at 0.5 MPa, while stepping up to a Ø25 yields 245.3 N. This Ø20 model sits perfectly in the middle for moderate push tasks. The CA rear pivot cover is ideal for applications requiring angular alignment during the stroke extension.
Note that the fixed bumpers only decelerate the piston near the end of travel; they do not function as a brake. If your system loses air or the valve is centred, the rod will drift, so add an external pilot check valve or rod lock to hold a suspended load securely. Position detection requires the built-in -S magnet, as standard non-magnet versions cannot accept sensors.
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 MI20X25SCA FAQ
At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it delivers 219.8 N push and 184.7 N pull. The theoretical maximum force is 32 kgf at 1.0 MPa. The air port size is 1/8".
No, the fixed TPU bumper pads only decelerate the piston at the stroke end and do not act as a lock. If air is lost, the rod will drift. For vertical loads, install an external rod lock or pilot-operated check valve.
