Airtac MI16-20 Stainless Steel Mini Cylinder MI20X225CA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X225CA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 225mm 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 MI20X225CA
Delivering 157 N of push force at 0.5 MPa, the AirTAC MI20X225CA is a double-acting round-body mini cylinder built for demanding automation. Its stainless-steel barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. The 225 mm stroke is well within the 500 mm maximum for this bore, making it highly versatile. Because it lacks the -S suffix, this specific SKU cannot accept magnetic position switches.
For practical sizing, plan for about 94 N of real work at 0.5 MPa, which safely lifts an 8 kg mass vertically with a 2:1 margin. The riveted construction keeps the body compact, while fixed TPU bumper pads absorb the impact at stroke extremes. Air connects via a 1/8 inch port, and the rear CA clevis equips the cylinder for pivot mounting.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X225CA Is Used
Package Diverter Gate
Pivots a sorting flap on a packaging line using the CA clevis, relying on the 157 N push force to redirect cartons at high speeds.
Textile Loom Tensioner
Adjusts yarn tension arms in humid textile facilities where the stainless-steel barrel prevents mild corrosion and maintains smooth movement.
Bin Lid Actuator
Lifts an 8 kg hopper lid vertically through a 225 mm arc, safely operating within the 2:1 load margin at 0.5 MPa.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X225CA the Right Cylinder?
When sizing this 20 mm bore, compare it directly with its neighbours: a 16 mm bore generates 100.5 N of push at 0.5 MPa, while stepping up to a 25 mm bore yields 245.3 N. Choose the 20 mm when you need to move roughly 8 kg vertically or apply around 94 N of working force. The 225 mm stroke provides ample travel but requires attention to side loading; ensure your front mounting guides the load to prevent rod bending over that distance.
The CA rear pivot cover is ideal for articulating mechanisms, but remember that standard double-acting operation means the piston will drift if air pressure drops. The fixed TPU bumpers only decelerate the end of stroke and do not act as a brake. To hold a load securely during an air loss event, install an external rod lock or a pilot-operated check valve. Since this SKU has no internal magnet, adding CMSG, DMSG or EMSG sensors is impossible without switching to the -S variant.
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 MI20X225CA FAQ
At 0.5 MPa this 20 mm bore cylinder provides 157 N of push and 131.9 N of pull. At 0.7 MPa it provides 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 inch.
Yes, the 20 mm bore uses the ISO 6432 mounting interface, so it drops directly into standard mini-cylinder brackets and clevises. However, because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG magnetic switches.
