Airtac MI16-20 Stainless Steel Mini Cylinder MI20X190CA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X190CA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 190mm 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 MI20X190CA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 190 mm stroke with a CA pivot clevis. The riveted barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Because the bore is Ø20, it conforms to ISO 6432 mounting dimensions, dropping smoothly into standard mini-cylinder brackets.
Fixed TPU bumper pads absorb the impact at stroke ends, decelerating the motion without offering adjustable cushioning. Plan for roughly 94 N of actual work at 0.5 MPa to maintain a safe margin, which translates to lifting about 8 kg vertically. Note that this specific SKU lacks the -S magnet, so it cannot host CMSG, DMSG or EMSG sensors.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X190CA Is Used
Package Diverter Gate
Actuates a routing flap on a packaging line, using the 190 mm stroke to shift cardboard cartons into a secondary lane with reliable 157 N push force.
Lab Sample Ejection
Ejects processed sample trays from a damp testing chamber, where the stainless-steel barrel prevents mild corrosion from repeated humidity exposure.
Textile Loom Tensioner
Pivots via the CA clevis to maintain tension on fabric threads, absorbing stroke-end impact with fixed TPU pads during rapid cycling.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X190CA the Right Cylinder?
If 157 N of push is too much, the Ø16 bore steps down to 100.5 N at 0.5 MPa; if you need more muscle, the Ø25 jumps up to 245.3 N. The 190 mm stroke is well within the 500 mm maximum for this bore, but at that length you should watch out for side loads and rod bending to avoid premature seal wear. The CA rear pivot cover is ideal for clevis mounting, and you can also use LB foot, FA flange, SDB pivot-block or TC trunnion fixtures.
Remember that the fixed bumpers only soften the end of travel; they do not act as a brake. If power or air is lost, the piston will drift. To lock a load in place, you must add an external rod lock or a pilot-operated check valve. For position feedback, you would need the -S magnet version to accept switches.
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 MI20X190CA FAQ
This 20 mm bore cylinder uses a 1/8" air port and an M8x1.25 male rod thread. At 0.5 MPa it pushes with 157 N and pulls with 131.9 N. At 0.7 MPa it pushes 219.8 N and pulls 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa.
Yes, the Ø20 bore uses the ISO 6432 mounting interface, so it fits standard mini-cylinder clevises and brackets. However, because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG sensors. You would need the magnet-equipped variant for position sensing.
