Airtac MI16-20 Stainless Steel Mini Cylinder MI16X25CAH
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X25CAH 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 MI16X25CAH
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 CA rear pivot cover provides a clevis mount for articulated motion, while the -H seal option equips the unit with high-temperature Viton FKM elastomers. Built with a riveted stainless barrel and rod, it shrugs off mild corrosion and washdown better than painted alternatives.
Because the 0.5 MPa thrust translates to roughly 5.1 kgf, you can plan for lifting a real part mass of about 2.5 kg vertically while keeping a safe 2:1 margin. The 1/8" port feeds the 6 mm piston rod, and fixed TPU bumper pads absorb the impact at both stroke ends. Note that this specific SKU lacks the -S magnet, so it cannot host CMSG, DMSG or EMSG reed switches.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X25CAH Is Used
Articulated Part Ejection
Uses the CA pivot clevis to swing and push light moulded components out of a press, leveraging the 100.5 N push force to clear the tooling safely.
High-Temp Diverting Gate
Deploys the Viton FKM -H seals to withstand ambient heat near an oven, actuating a routing flap for packaged goods on a 1/8" ported pneumatic line.
Compact Vertical Lift
Lifts small tote latches weighing roughly 2.5 kg in a packaging cell, operating well within the 5.1 kgf theoretical limit at 0.5 MPa.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X25CAH the Right Cylinder?
When sizing this 16 mm bore, compare it against its neighbours: a 12 mm bore yields 56.5 N of push at 0.5 MPa, whereas stepping up to a 20 mm bore provides 157 N. This 25 mm stroke keeps the rod compact and minimizes side-load bending moments. If your process drops air pressure or centres the valve, the piston will drift, as the TPU pads only decelerate the end of travel rather than locking the load. For suspended loads, add an external rod lock or a pilot check valve. To track position, select the -S magnet version instead, as this variant cannot accept sensors.
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 MI16X25CAH 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, and the air port size is 1/8".
The 16 mm bore uses the ISO 6432 mounting interface, so it drops directly into standard mini-cylinder brackets and clevises. However, because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG switches. You must choose the -S variant for position sensing.
