About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X80SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles demanding 80 mm stroke tasks. The Ø20 mm bore operates on a 1/8" port and features a CA rear pivot cover for clevis mounting. Its stainless barrel and rod resist mild corrosion, outperforming painted alternatives in damp environments.
Equipped with a piston magnet, the unit supports CMSG, DMSG and EMSG sensors for position detection. Fixed TPU bumper pads absorb stroke-end impact. For real-world sizing, plan for roughly 94 N of actual work at 0.5 MPa, which means it lifts about 8 kg vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X80SCA Is Used
Package Diverter
Pushes light cartons on a packaging line using the 80 mm stroke, relying on the 1/8" port for rapid actuation.
Textile Loom Tensioner
Maintains thread tension via the CA pivot clevis, absorbing end-of-stroke shocks through fixed TPU bumpers.
Lab Sample Ejector
Ejects test tubes from a carousel, leveraging the stainless steel rod for washdown durability in wet labs.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X80SCA the Right Cylinder?
Sizing this 157 N unit against its neighbours helps narrow the choice: step down to the Ø16 bore for 100.5 N, or up to the Ø25 for 245.3 N at 0.5 MPa. The CA back cover provides a rear pivot point, while the included magnet enables direct sensor mounting. If your application requires the rod to stay put during air loss, note that this cylinder will drift; add an external rod lock or pilot check valve for secure load holding.
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 MI20X80SCA FAQ
This Ø20 mm bore cylinder uses a 1/8" port. It generates 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa.
