Airtac MI16-20 Stainless Steel Mini Cylinder MI20X165SU
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X165SU is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 165mm 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 MI20X165SU
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 165 mm stroke with a 1/8 inch air port. The riveted stainless barrel and Ø8 mm rod shrug off mild corrosion, making it far superior to painted alternatives in damp washdown environments. Fixed TPU bumper pads absorb the impact at stroke extremes without needing adjustment.
Because it conforms to the ISO 6432 mounting interface, the body drops directly into standard mini-cylinder brackets and clevises. For real-world sizing, plan for a safe working load of about 94 N, which means it can reliably lift an 8 kg part vertically with a 2:1 safety margin. The built-in magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X165SU Is Used
Package Diverter Gate
Pushes lightweight cardboard cartons on a packaging line using 157 N of thrust, with the U cover providing a stable 90-degree pivot for the diverter arm.
Lab Sample Ejection
Ejects processed fluid samples from a testing carousel, where the stainless construction resists chemical mist and the 165 mm stroke clears the workstation.
Bin Lid Actuation
Lifts an 8 kg access hatch on an automated storage bin, utilising the safe vertical lift capacity while CMSG sensors confirm the fully open position.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X165SU the Right Cylinder?
When sizing this 20 mm bore, compare it against its neighbours: a 16 mm bore yields 100.5 N of push at 0.5 MPa, while stepping up to a 25 mm bore provides 245.3 N. This model includes a U back cover for 90-degree mounting and an integrated magnet for electronic sensors. If your mechanism drops air pressure or the valve centres, the piston will drift; these bumpers only decelerate the end of travel and act as neither a lock nor a brake. Use a pilot-operated check valve or external rod lock to hold a suspended load. At 165 mm of extension, ensure your end-of-stroke alignment is true to prevent rod bending under side loads.
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 MI20X165SU FAQ
This 20 mm bore cylinder uses a 1/8 inch port. 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 force of 32 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in piston magnet compatible with CMSG, DMSG and EMSG switches. The U back cover mounts at 90 degrees, and the body uses standard ISO 6432 mounting dimensions for easy bracket interchange.
