Airtac MI16-20 Stainless Steel Mini Cylinder MI20X35SCM
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X35SCM is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 35mm 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 MI20X35SCM
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation with ease. The riveted Ø20 mm barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Its 1/8" port feeds the 30-800 mm/s speed range, while fixed TPU bumper pads absorb the impact at stroke ends.
Because the piston pushes with 157 N, you can plan for roughly 94 N of actual work at 0.5 MPa. That same force translates to lifting about 8 kg vertically with a 2:1 safety margin. The built-in magnet (-S) supports CMSG, DMSG and EMSG switches, and the CM round end cover tailors the rear mounting orientation for tight spaces.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X35SCM Is Used
Diverter Gate Actuation
Snaps a sorting flap on a packaging line using 157 N of push force, with the stainless build surviving humid washdown environments.
Small Press Ejection
Kicks lightweight stamped parts out of a die area using the 35 mm stroke, relying on the fixed TPU pads to halt the rod smoothly.
Carton Lid Closing
Swings a hinged lid down on packed boxes, lifting roughly 8 kg vertically while the CM round cover allows compact rear pivoting.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X35SCM the Right Cylinder?
If 157 N is too much, step down to the Ø16 bore which supplies 100.5 N at 0.5 MPa; if you need more muscle, the Ø25 bore pushes 245.3 N. This SKU includes the -S magnet for position sensing, plus a CM round rear cover. Remember that a standard cylinder drifts if air pressure drops or the valve centres—the fixed TPU pads only soften the stroke end, so add an external rod lock or pilot check valve to hold a suspended load. With a 35 mm stroke, side-load stress on the Ø8 mm rod is minimal, but keep the load aligned to prevent premature wear.
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 MI20X35SCM FAQ
At 0.5 MPa it pushes 157 N and pulls 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. Air connects via a 1/8" port, and the male rod thread is M8x1.25.
Yes, the Ø20 mm body uses the ISO 6432 mounting interface, so it drops into standard mini-cylinder brackets and clevises. Because this model includes the -S magnet, you can mount CMSG, DMSG or EMSG reed and electronic switches directly for position detection.
