Airtac MI16-20 Stainless Steel Mini Cylinder MI16X85SU
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X85SU is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 85mm 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 MI16X85SU
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation with ease. The riveted construction uses a stainless barrel and rod to resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. Its 85 mm stroke and built-in piston magnet make it immediately ready for position sensing.
The Ø16 bore accepts a 1/8" port and features a 90-degree U rear cover for flexible mounting. Because the bore falls within the Ø8-Ø25 range, it uses the ISO 6432 mounting interface, dropping directly into standard mini-cylinder brackets and clevises. Plan for roughly 60 N of actual work at 0.5 MPa, which means it can safely lift about 5.1 kg vertically against gravity.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X85SU Is Used
Diverter Gate Actuation
Pushes lightweight sorting flaps on packaging lines, using the 85 mm stroke to clear passing cartons reliably.
Lab Sample Ejection
Ejects plastic sample trays from test enclosures, where the stainless body resists humidity and chemical wipe-downs.
Small Part Seating
Presses sub-assemblies into recessed pockets with a safe 60 N working force to avoid damaging delicate components.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X85SU the Right Cylinder?
When sizing this 16 mm bore, compare it against its neighbours: a 12 mm bore gives 56.5 N of push at 0.5 MPa, while stepping up to a 20 mm bore yields 157 N. The 85 mm stroke is well within the 500 mm maximum, but at extended lengths you should watch for side-load and rod-bending forces. The built-in magnet (-S) supports CMSG, DMSG and EMSG switches, while the 90-degree U back cover simplifies port and pivot alignment.
Remember that a standard cylinder drifts if air pressure drops or the valve is centred; the fixed TPU bumper pads only decelerate the stroke end and do not function as a brake. To hold a load securely in place during an air loss event, incorporate an external rod lock or a pilot-operated check valve into your 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 MI16X85SU FAQ
At 0.5 MPa it provides 100.5 N push and 86.4 N pull. At 0.7 MPa it provides 140.7 N push and 120.9 N pull. The theoretical maximum force is 20.5 kgf at 1.0 MPa. This 16 mm bore model uses a 1/8" port.
No, the piston will drift if air is lost or the valve is centred. The fixed TPU bumper pads only soften the impact at stroke end and do not act as a lock. Use an external rod lock or pilot check valve for holding.
