Airtac MI16-20 Stainless Steel Mini Cylinder MI20X35U
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X35U 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 MI20X35U
Delivering 157 N of push force at 0.5 MPa, the AirTAC MI20X35U is a compact double-acting round-body mini cylinder built for demanding environments. Its stainless-steel barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown areas. The riveted construction keeps the unit light, while fixed TPU bumper pads absorb impact energy at the stroke extremes. Because this specific SKU lacks the -S magnet suffix, it cannot accept CMSG, DMSG, or EMSG position switches.
With a 20 mm bore and 35 mm stroke, this model uses a 1/8" air port and an M8x1.25 male rod thread. It conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets. For practical sizing, plan for roughly 94 N of actual work at 0.5 MPa, which means it can comfortably lift about 8 kg vertically with a 2:1 safety margin. The U suffix indicates a 90-degree rear cover, orienting the port neatly for tight machinery layouts.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X35U Is Used
Package Diverters
Provides the 157 N push force needed to actuate lightweight routing gates on packaging conveyors, withstanding humid packing-room environments.
Lab Dispensing Heads
Handles precise 35 mm strokes for chemical dosing heads, where the stainless body prevents mild corrosion from accidental solvent splashes.
Textile Guiders
Drives yarn guide mechanisms at speeds up to 800 mm/s, relying on the 90-degree U cover to keep the 1/8" port neatly out of the way.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X35U the Right Cylinder?
When sizing this 20 mm bore, compare it against its neighbors: the smaller MI16 generates 100.5 N of push, while the larger MI25 provides 245.3 N at 0.5 MPa. If your application needs true position holding on air loss, note that a plain cylinder drifts when the valve centers—the TPU bumpers only decelerate the stroke end, so you must add an external rod lock or pilot check valve for secure load holding. The 35 mm stroke is short enough to minimize rod bending, but always verify side-load alignment to prevent premature seal wear. To add sensing later, you must switch to the -S magnet 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 MI20X35U FAQ
This double-acting cylinder pushes with 157 N and pulls with 131.9 N at 0.5 MPa. At 0.7 MPa, push increases to 219.8 N and pull to 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa. It features a 1/8" air port and an 8 mm piston rod.
Yes, the 20 mm bore uses the ISO 6432 mounting interface, so it fits standard mini-cylinder clevises and foot brackets directly. However, because this SKU lacks the -S magnet, it cannot support CMSG, DMSG, or EMSG magnetic switches without changing to a magnetized variant.
