Airtac MI16-20 Stainless Steel Mini Cylinder MI20X80U
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X80U is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 80mm 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 MI20X80U
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles an 80 mm stroke with a 1/8" port. The riveted barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp washdown zones. Its fixed TPU bumper pads absorb stroke-end impact without needing adjustment.
Because the 157 N rating leaves a safety margin, plan for roughly 94 N of actual work at 0.5 MPa. This translates to lifting about 8 kg vertically with a 2:1 safety factor. The rear U cover mounts at 90 degrees for compact lateral port routing, while the Ø20 body uses the standard ISO 6432 mounting interface to fit common mini brackets.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X80U Is Used
Package Diverter Gate
Actuates a routing flap on a packaging conveyor, using the 157 N push force to redirect small cartons at high speed.
Film Roll Tensioner
Maintains wrapping tension on a packaging line, where the stainless build withstands humid cleaning environments.
Component Ejector
Pushes machined plastic parts out of a mold cavity, relying on the 90-degree U cover to keep airlines tight against the machine frame.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X80U the Right Cylinder?
When sizing this 80 mm stroke model, verify your load against the 131.9 N pull force at 0.5 MPa. If you need less power, the Ø16 bore provides 100.5 N push; stepping up to the Ø25 yields 245.3 N. For this 80 mm length, keep side-load forces minimal to avoid bending the Ø8 rod. The U-style rear cover simplifies spatial constraints by orienting the air supply at 90 degrees.
This SKU lacks the -S magnet, so it cannot accept CMSG, DMSG or EMSG position switches. If sensing is required, select an -S variant. Remember that venting the air causes the piston to drift, as the TPU pads only decelerate the stroke end rather than locking the load.
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 MI20X80U FAQ
This double-acting cylinder uses a 1/8" port and generates 157 N push / 131.9 N pull at 0.5 MPa, and 219.8 N push / 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa.
No, this specific SKU lacks a piston magnet, so it cannot accept CMSG, DMSG or EMSG switches. You must order an -S variant for sensing. The cylinder uses the ISO 6432 mounting interface and fixed TPU bumper pads for deceleration.
