Airtac MI16-20 Stainless Steel Mini Cylinder MI16X5SU
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X5SU is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 5mm 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 MI16X5SU
Generating about 100 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles very short 5 mm movements with precision. The riveted stainless barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. Because it uses the ISO 6432 mounting interface, it drops directly into standard mini-cylinder brackets and clevises.
The built-in piston magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing, while the U back cover provides a 90-degree port and mounting orientation for cramped machinery. Fixed TPU bumper pads decelerate the stroke end, and the 1/8" port ensures reliable air flow. Plan for roughly 60 N of actual work at 0.5 MPa, which means it can safely lift about 5.1 kg vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X5SU Is Used
Micro-Clamping
Secures delicate electronic components on a PCB assembly line using the precise 5 mm stroke without damaging the part.
Small Part Ejection
Pushes lightweight plastic mouldings out of a sub-assembly fixture using a safe working load of 60 N.
Flap Folding
Tucks cardboard packaging flaps on a compact indexing table where the 90-degree U cover fits tight clearances.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X5SU the Right Cylinder?
When sizing this 16 mm bore, compare it against neighbours: the smaller Ø12 generates 56.5 N push, whereas the larger Ø20 provides 157 N at 0.5 MPa. This 5 mm stroke is ideal for micro-clamping or ejecting small parts where a longer rod would buckle. If your application must hold a vertical load when air is removed, note that the piston will drift; you should add an external rod lock or pilot-operated check valve, as the TPU bumpers only soften the end of travel and act purely as a decelerator, never a brake. The U-style rear cover suits compact 90-degree mounting footprints.
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 MI16X5SU FAQ
This 16 mm bore cylinder features a 1/8" port and a 6 mm rod. It generates 100.5 N push and 86.4 N pull at 0.5 MPa, 140.7 N push and 120.9 N pull at 0.7 MPa, with a theoretical maximum force of 20.5 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in magnet for CMSG, DMSG or EMSG switches. The U back cover provides a 90-degree mounting and port orientation, and the body conforms to ISO 6432 mounting dimensions for standard brackets.
