About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100CAH
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles robust 100 mm linear motion tasks. The riveted barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Its 1/8" port feeds the 8 mm rod to cycle at 30-800 mm/s.
Equipped with a CA pivot clevis and high-temperature Viton seals, it drops directly into standard ISO 6432 mini-cylinder brackets. Plan for roughly 94 N of real work at 0.5 MPa, which means it lifts about 8 kg vertically with a 2:1 safety margin. Fixed TPU bumpers absorb the end-of-stroke impact.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100CAH Is Used
Diverter Gate Actuation
Pushes a sorting flap with 157 N at 0.5 MPa, reliably routing small packages on a washdown-ready stainless conveyor line.
Heat-Seal Jaw Pivot
Uses the CA clevis to swing a sealing arm, with Viton seals surviving the ambient radiated heat near film packaging equipment.
Component Ejector
Provides an 8 kg vertical lift margin to eject molded parts from a fixture, absorbing end-stroke impact with fixed TPU bumpers.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100CAH the Right Cylinder?
When sizing this 20 mm bore, the smaller 16 mm option yields 100.5 N push, while the larger 25 mm provides 245.3 N at 0.5 MPa. This 100 mm stroke is well within the 500 mm maximum, though side loads on the 8 mm rod should still be minimized to prevent bending. The CA rear clevis suits pivoting loads.
This SKU lacks the -S magnet, so it cannot accept CMSG, DMSG or EMSG switches. Remember that air loss causes the piston to drift; use a pilot check valve to hold a suspended load, as the TPU pads only decelerate and never lock the rod.
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 MI20X100CAH FAQ
It features a 1/8" port and an 8 mm rod. The double-acting thrust is 157 N push and 131.9 N pull at 0.5 MPa, rising to 219.8 N push and 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa.
No, this specific SKU lacks the -S magnet, so CMSG, DMSG and EMSG switches will not function. You must select the -S variant for sensing. It uses the ISO 6432 mounting interface and fixed TPU bumper pads for stroke deceleration.
