Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100R
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100R is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 100mm 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 MI20X100R
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 100 mm stroke with a 1/8" air port. The riveted barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown zones. Its fixed TPU bumper pads absorb stroke-end impact without needing adjustment.
Because it conforms to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises. Plan for roughly 94 N of actual work at 0.5 MPa, or expect it to lift about 8 kg vertically with a safe 2:1 margin. Note this SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100R Is Used
Package Diverter Gate
Pushes light cardboard cartons on a washdown packaging line, using the 100 mm stroke to swing a diverter arm without risking corrosion from damp environments.
Textile Loom Tensioner
Maintains thread tension by extending a guide roller, relying on the 131.9 N pull force at 0.5 MPa to counteract fiber drag in a humid production room.
Lab Sample Ejector
Ejects plastic test tubes from a centrifuge carousel, where the stainless body resists chemical splashes and the 8 kg vertical lift margin easily clears the rack.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100R the Right Cylinder?
If 157 N of push is too much, step down to the Ø16 bore which provides 100.5 N at 0.5 MPa; if you need more power, the Ø25 bore offers 245.3 N. This 100 mm stroke is well within the 500 mm maximum, but long rods invite side-load bending, so keep the load guided. The R back cover features an axial-in port orientation for tidy plumbing.
Remember that venting the air causes the piston to drift, as the TPU pads only decelerate the end of travel rather than locking the load. To hold a vertical position securely, install an external rod lock or a pilot-operated check valve. Since this specific unit has no -S magnet, position sensing is impossible without switching to the magnet-equipped 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 MI20X100R FAQ
The 1/8" ported Ø20 bore generates 157 N push and 131.9 N pull at 0.5 MPa, or 219.8 N push and 184.7 N pull at 0.7 MPa. Its theoretical maximum force is 32 kgf at 1.0 MPa.
Yes, it uses standard ISO 6432 mounting dimensions for easy bracket integration. However, because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG sensors; you must select the magnet-equipped version for position detection.
