About the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X180SU
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 180 mm stroke with ease. The Ø16 bore uses a 1/8" port and an M6x1.0 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Fixed TPU bumper pads absorb the impact at stroke end, while the rolled riveted body keeps the unit compact.
Thanks to the built-in -S magnet, you can mount CMSG, DMSG or EMSG switches for position sensing. The U back cover provides a 90-degree mounting orientation. For practical sizing, plan for roughly 60 N of actual work at 0.5 MPa, which equates to lifting about 5.1 kg vertically with a safe 2:1 margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X180SU Is Used
Package Diverter Gate
Pushes light cardboard cartons on a packaging line using the 100.5 N push force, with the U cover allowing a 90-degree pivot mount alongside the belt.
Lab Sample Ejection
Ejects plastic test tubes from a washing station where the stainless steel barrel prevents mild corrosion from repeated chemical splashes.
Small Parts Sorting
Actuates a sorting flap for lightweight plastic components, using the built-in magnet and a DMSG sensor to confirm the 180 mm stroke completion.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X180SU the Right Cylinder?
When sizing this unit, the Ø12 bore offers a smaller footprint with 56.5 N push at 0.5 MPa, whereas stepping up to the Ø20 bore yields 157.0 N if your payload exceeds the 5.1 kg vertical lift capacity of this Ø16 model. The 180 mm stroke is well within the 500 mm maximum standard stroke, though at this length you should minimize side loading to prevent rod bending. The ISO 6432 mounting interface drops directly into standard mini-cylinder brackets and clevises.
Because the base MI relies on fixed TPU bumpers rather than a locking mechanism, the piston will drift if air pressure drops or the valve is centered. To suspend a load safely mid-stroke, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 MI16X180SU FAQ
This double-acting cylinder features a 1/8" port and an M6x1.0 male rod thread. 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.
No, the base MI uses fixed TPU bumper pads to decelerate at the stroke end, not an adjustable air cushion. Additionally, it cannot hold a load if air is lost; you must add an external rod lock or pilot check valve to prevent drifting.
