Airtac MI16-20 Stainless Steel Mini Cylinder MI20X340SCA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X340SCA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 340mm 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 MI20X340SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 340 mm stroke with ease. The Ø20 mm bore uses a 1/8" port and an M8x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Riveted construction keeps the body compact, while fixed TPU bumper pads absorb the impact at stroke ends without offering adjustable cushioning.
For practical sizing, plan for about 94 N of real work at 0.5 MPa, which safely lifts an 8 kg part vertically with a 2:1 margin. The built-in piston magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing. A CA pivot clevis back cover equips this unit for articulated rod-end loads.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X340SCA Is Used
Package Diverter Gate
Pushes a routing flap on a packaging line, using the 157 N thrust to redirect cartons at 0.5 MPa without overstressing the mechanical stops.
Textile Loom Tensioner
Maintains yarn tension via the CA pivot clevis, accommodating rod swing while the 340 mm stroke takes up slack during material feed.
Lab Sample Ejection
Ejects processed vials from a test carousel, where the stainless build resists chemical exposure and the DMSG sensor confirms full extension.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X340SCA the Right Cylinder?
Sizing this 340 mm stroke model requires checking both neighbours: the Ø16 bore provides 100.5 N push at 0.5 MPa, while the Ø25 bore offers 245.3 N. If your payload is lighter, the Ø16 saves space; for heavier drives, step up to Ø25. At 340 mm, the Ø8 mm rod is long enough that side loads can induce bending—keep the load guided and axial to prevent premature seal wear.
Because this is a double-acting cylinder, air drives both directions and the TPU pads only decelerate the end of travel. If the air supply drops or the valve centres, the piston will drift and drop the load; use an external pilot check valve or rod lock if you need strict position holding. The CA rear clevis pairs with the ISO 6432 mounting interface to drop directly into standard mini-cylinder brackets.
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 MI20X340SCA FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N. At 0.7 MPa it pushes 219.8 N and pulls 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa. The air port is 1/8" and the male rod thread is M8x1.25.
The -S suffix means it has a built-in magnet for CMSG, DMSG and EMSG switches. It uses fixed TPU bumper pads to decelerate at the ends, not an adjustable air cushion (for that you need the MIC variant). The CA back cover provides a pivot clevis mount.
