Airtac MI16-20 Stainless Steel Mini Cylinder MI16X20U
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X20U is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 20mm 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 MI16X20U
Delivering 100.5 N of push force at 0.5 MPa, the AirTAC MI16X20U is a compact double-acting round-body mini cylinder built for tight spaces. Its stainless-steel barrel and Ø6 mm piston rod shrug off mild corrosion, giving it a real edge over painted-steel alternatives in damp or washdown-prone environments. The riveted construction keeps the body light, while fixed TPU bumper pads absorb the impact at stroke end to protect your mechanism. A 90-degree U rear cover simplifies port and mounting orientation in cramped machinery.
Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches. For practical sizing, plan for about 60 N of real work at 0.5 MPa rather than the absolute maximum, which translates to safely lifting a 5.1 kg mass vertically with a 2:1 margin. The 1/8" port feeds air to both extend and retract the rod smoothly across the 30-800 mm/s speed range.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X20U Is Used
PCB Clamp Actuator
Provides 60 N of safe clamping pressure on an electronics assembly line, holding delicate boards steady during automated soldering.
Carton Flap Folder
Uses its 20 mm stroke to rapidly fold small corrugated box flaps, relying on the 90-degree U cover to fit within narrow conveyor frames.
Lab Dispenser Push
Drives a precision pump head in a beverage testing lab, where the stainless body resists daily moisture and chemical wipe-downs.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X20U the Right Cylinder?
Choosing this 16 mm bore hits a practical middle ground: step down to an Ø12 unit if your load needs under 56.5 N at 0.5 MPa, or move up to a Ø20 bore when 157.0 N is required to shift heavier masses. The 20 mm stroke keeps the rod short and highly resistant to bending under side loads. If your mechanism must stay put during an air loss or when the valve is centred, remember the piston will drift; the TPU pads only soften the end of travel. You will need an external pilot check valve or a dedicated rod lock to hold a suspended load safely in place.
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 MI16X20U FAQ
This double-acting cylinder uses a 1/8" air port and a Ø6 mm rod with an M6x1.0 male thread. It generates 100.5 N push and 86.4 N pull at 0.5 MPa, rising to 140.7 N push and 120.9 N pull at 0.7 MPa. The theoretical maximum force is 20.5 kgf at 1.0 MPa.
The Ø16 bore uses the ISO 6432 mounting interface, so it drops directly into standard mini-cylinder clevises and foot brackets. However, because this specific SKU lacks the -S magnet, it cannot host CMSG, DMSG or EMSG magnetic switches; you would need the -S variant for position sensing.
