Airtac MI16-20 Stainless Steel Mini Cylinder MI16X25U
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X25U is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 25mm 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 MI16X25U
Generating about 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles compact actuation with ease. The 16 mm bore uses a 1/8 inch air port and a 6 mm piston rod with an M6x1.0 male thread. Its round-body, riveted construction shrinks the footprint while the stainless barrel and rod resist mild corrosion in damp environments. Fixed TPU bumper pads absorb the impact at stroke extremes, decelerating the piston without the complexity of an adjustable cushion.
Because the 100.5 N rating is a theoretical maximum, you should plan for roughly 60 N of actual work at 0.5 MPa. That translates to safely lifting a 5.1 kg part vertically with a 2:1 safety margin. The U back cover orients the port 90 degrees to the body, simplifying hose routing in tight machinery. Since this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X25U Is Used
Component Ejection
Pushes small machined aluminium parts out of a CNC chuck using the 90-degree U cover port to keep airlines flush against the machine bed.
Flap Folding
Folds corrugated cardboard flaps on a compact packaging line, utilizing the 25 mm stroke to clear the path for the sealing head.
Sorter Diverter
Acts as a high-speed diverter gate on a stainless-steel food conveyor, where the riveted round body withstands routine washdown spray.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X25U the Right Cylinder?
When sizing this 16 mm bore, verify your load against the 60 N safe working threshold. If your application needs less force, dropping to the 12 mm bore yields 56.5 N of push at 0.5 MPa. Conversely, stepping up to the 20 mm bore provides 157.0 N. The short 25 mm stroke keeps the rod compact and highly resistant to bending, but always ensure the load travels cleanly along the axis. The ISO 6432 mounting interface means it drops directly into standard mini-cylinder brackets and clevises.
Remember that venting the air or centering the directional valve causes the piston to drift, as the TPU pads only soften the end of travel rather than locking the rod. You must add an external pilot-operated check valve or a rod lock to suspend a vertical load safely. If you require position feedback, select the -S magnet variant instead of this non-magnetic model to enable sensor mounting.
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 MI16X25U FAQ
This 16 mm bore cylinder features a 1/8 inch air port and generates 100.5 N push and 86.4 N pull at 0.5 MPa. At 0.7 MPa, the push increases to 140.7 N and the pull to 120.9 N. The theoretical maximum force is 20.5 kgf at 1.0 MPa.
No, this specific SKU lacks the internal magnet required for switches. You must choose the -S variant to use CMSG, DMSG or EMSG sensors. The unit uses fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable air cushion.
