Airtac MI16-20 Stainless Steel Mini Cylinder MI20X150R
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X150R is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 150mm 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 MI20X150R
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 150 mm stroke with a rugged riveted construction. The Ø20 mm bore uses a 1/8" port and an M8x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. The rear R cover configures the air supply axially inline with the body.
Because the 157 N rating leaves a margin for friction, plan for roughly 94 N of actual work at 0.5 MPa. In vertical lifting tasks, this translates to hoisting about 8 kg safely with a 2:1 factor. Fixed TPU bumper pads absorb the impact at stroke extremes, and the standard ISO 6432 mounting interface lets you drop this unit straight into common mini-cylinder brackets.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X150R Is Used
Package Diverter Gate
Pushes lightweight cardboard cartons on a packaging line using 157 N of thrust, with the rear R cover keeping the airline neatly out of the way.
Lab Sample Ejection
Ejects plastic test tubes from a testing carousel over a 150 mm travel, where the stainless rod shrugs off occasional chemical splashes.
Textile Yarn Guide
Shifts a yarn guide arm across a weaving machine, relying on the fixed TPU pads to soften the 30-800 mm/s stroke ends without scuffing the thread.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X150R the Right Cylinder?
When sizing this unit, the smaller Ø16 bore yields 100.5 N of push at 0.5 MPa, while the larger Ø25 bore jumps to 245.3 N, helping you bracket your exact force needs. The 150 mm stroke is well within the 500 mm maximum, but at this length you should watch for side loads to prevent rod bending. The R back cover supplies an axial port orientation for tight linear layouts.
This specific SKU lacks the -S magnet, so it cannot host CMSG, DMSG or EMSG sensors; add the -S variant if you require position detection. Furthermore, the fixed bumpers only decelerate the stroke end and do not act as a brake. If the mechanism must hold a load vertically when air is lost or the valve is centered, the piston will drift, requiring an external rod lock or pilot check valve.
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 MI20X150R FAQ
This Ø20 mm bore cylinder features a 1/8" port and an M8x1.25 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 of 32 kgf at 1.0 MPa.
Yes, the Ø20 mm body conforms to ISO 6432 mounting dimensions, so it fits standard mini-cylinder clevises and foot brackets. However, because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG switches; you must select the -S version for position sensing.
