About the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X70U
Delivering 100.5 N of push force at 0.5 MPa, the AirTAC MI16X70U is a double-acting round-body mini cylinder built from a stainless-steel barrel and rod. Its riveted construction resists mild corrosion, giving it a distinct advantage over painted alternatives in damp or washdown environments. The unit features a 90-degree U back cover and a 1/8 inch port for neat, compact routing.
Because it lacks the -S suffix, this specific SKU cannot host CMSG, DMSG or EMSG magnetic sensors. For position feedback, the -S magnet variant is required. Plan for roughly 60 N of actual work at 0.5 MPa, which translates to lifting about 5.1 kg vertically with a 2:1 safety margin. Fixed TPU bumper pads absorb the stroke-end impact, operating effectively across a 30-800 mm/s speed range.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X70U Is Used
Bottle Diverter Gate
Actuates a lightweight stainless flap to sort plastic bottles on a washdown beverage line, utilising the 100.5 N push force to overcome guide friction.
Carton Flap Folder
Folds small cardboard flaps prior to sealing, with the 90-degree U cover allowing the air line to route cleanly parallel to the machine frame.
Component Ejector
Pushes finished injection-moulded parts out of a jig, relying on the fixed TPU bumpers to soften the impact at the end of the 70 mm extension.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X70U the Right Cylinder?
When sizing this 16 mm bore, the smaller Ø12 generates 56.5 N of push at 0.5 MPa, while the larger Ø20 provides 157.0 N, allowing you to step up or down based on your exact force needs. The 70 mm stroke is well within the 500 mm maximum standard limit, keeping the unit readily available. Its ISO 6432 mounting interface means it drops directly into standard mini-cylinder brackets and clevises.
Remember that a plain double-acting cylinder drifts when air is lost or the valve is centered, as the fixed TPU pads only decelerate the end of travel rather than locking the rod. To suspend a load safely, 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 MI16X70U 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. The air port is 1/8 inch and the male rod thread is M6x1.0.
No, because this SKU lacks the -S suffix, there is no internal magnet and it cannot host CMSG, DMSG or EMSG switches. You must select the -S variant for position sensing. It uses the ISO 6432 mounting interface for standard brackets.
