Airtac MI16-20 Stainless Steel Mini Cylinder MI20X70CA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X70CA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 70mm 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 MI20X70CA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 70 mm stroke with a CA pivot clevis. The riveted barrel and Ø8 mm rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Because it follows ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets.
Plan for roughly 94 N of actual work at 0.5 MPa, which equates to lifting about 8 kg vertically with a safe 2:1 margin. The 1/8" port feeds air to extend and retract the rod, while fixed TPU bumper pads absorb the impact at stroke end. Note that this specific SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors without switching to an -S variant.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X70CA Is Used
Package Diverter Gate
Pivots a sorting flap on a packaging line using the CA clevis, applying 157 N at 0.5 MPa to push cardboard cartons onto a secondary belt.
Lab Sample Ejector
Ejects processed fluid samples from a test station over a 70 mm travel, where the stainless build resists chemical mist and mild washdown.
Tote Pusher Arm
Shoves lightweight plastic totes into a loading chute, safely managing the 8 kg vertical lift equivalent without overloading the rod.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X70CA the Right Cylinder?
When sizing this 20 mm bore, the smaller Ø16 generates 100.5 N of push at 0.5 MPa, whereas stepping up to the Ø25 yields 245.3 N, letting you tune the force to the exact payload. The included CA rear clevis is ideal for pivot mounting, complemented by available LB foot, FA flange or TC trunnion options. Since this model has no -S suffix, magnetic position sensing is not supported.
Keep in mind that the fixed TPU bumpers only decelerate the piston near the end of travel; they do not act as a brake. If your application must hold a vertical load when air pressure drops or the valve is centered, you will need an external rod lock or a pilot-operated check valve to prevent drift.
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 MI20X70CA FAQ
This 20 mm bore cylinder uses 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 force of 32 kgf at 1.0 MPa.
No, because this SKU lacks the internal magnet. To use CMSG, DMSG or EMSG switches, you must specify the -S variant. This version relies on fixed TPU bumper pads to decelerate the stroke end and conforms to ISO 6432 mounting dimensions.
