Airtac MI16-20 Stainless Steel Mini Cylinder MI16X55CA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X55CA is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 55mm 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 MI16X55CA
Delivering 100.5 N of push force at 0.5 MPa, the AirTAC MI16X55CA is a double-acting round-body mini cylinder built for compact automation. Its stainless-steel barrel and Ø6 mm piston rod shrug off mild corrosion, giving it a real edge over painted-steel alternatives in damp or washdown-prone environments. The riveted construction keeps the body light, while fixed TPU bumper pads absorb the impact at stroke ends to protect your mechanism. This specific SKU features a CA rear pivot cover for clevis mounting and uses a 1/8" air port.
Because it lacks the -S suffix, this base model cannot host CMSG, DMSG or EMSG magnetic switches. In practical terms, you can expect a safe working load of about 60 N at 0.5 MPa, which translates to lifting a 5.1 kg part vertically with a 2:1 safety margin. The Ø16 bore falls right into the ISO 6432 mounting interface standard, so it drops directly into standard mini-cylinder brackets without needing custom hardware.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X55CA Is Used
Textile Loom Tensioning
Uses the CA pivot bracket to maintain consistent yarn tension, applying up to 60 N of controlled force in humid weaving facilities where the stainless rod resists fibre dust and moisture.
Bottle Capping Pivot
Ideal for applying torque and downward pressure on plastic caps, where the 5.1 kg vertical lift capacity and rear clevis mount allow smooth articulation on rotary filling lines.
Small Parts Ejection
Ejects lightweight moulded components from a 16 mm bore fixture, utilising the 140.7 N push force at 0.7 MPa and fixed TPU bumpers to prevent damage at the end of the 55 mm stroke.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X55CA 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 a 20 mm bore offers 157.0 N. If your task demands holding a load vertically during an air loss or valve centre, remember this plain cylinder will drift; the TPU bumpers only decelerate the end of stroke and act neither as a lock nor a brake. You would need an external rod lock or pilot-operated check valve to hold position. For applications requiring position feedback, step up to the -S magnet variant to enable sensing switches. The 55 mm stroke is well within the 500 mm maximum, but always ensure the CA clevis mount accommodates any side-load to avoid rod bending.
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 MI16X55CA FAQ
This Ø16 mm bore cylinder uses a 1/8" air port and a Ø6 mm rod with an M6x1.0 male thread. The double-acting thrust is 100.5 N push and 86.4 N pull at 0.5 MPa, increasing to 140.7 N push and 120.9 N pull at 0.7 MPa. The theoretical maximum force is 20.5 kgf at 1.0 MPa.
No, because this specific SKU lacks the -S suffix, it does not have an internal magnet and cannot host CMSG, DMSG or EMSG switches. You would need to specify the MI16X55CA-S variant to enable magnetic position sensing. The unit relies on its fixed TPU bumper pads to decelerate the stroke end.
