Airtac MI16-20 Stainless Steel Mini Cylinder MI20X700SCA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X700SCA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 700mm 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 MI20X700SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles long-reach actuation with a 700 mm stroke. Because 700 mm exceeds the 500 mm standard maximum for this bore, it is supplied as a made-to-order unit. The stainless barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Its riveted construction keeps the body compact, while fixed TPU bumper pads absorb impact energy at the stroke ends.
This specific configuration includes a CA rear pivot cover for clevis mounting and a built-in piston magnet (-S) for position sensing. The 1/8" port drives the 8 mm rod to cycle at 30-800 mm/s. In practical terms, you can plan for about 94 N of real work at 0.5 MPa, which translates to lifting an 8 kg part vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X700SCA Is Used
Long-Reach Diverter
Extends 700 mm across a wide conveyor belt to push mismatched cartons into a reject chute in packaging lines.
Vertical Parts Lift
Raises lightweight 8 kg plastic totes between elevator tiers using the 157 N push force and CA clevis pivot.
Film Roll Ejector
Ejects finished winding rolls from a slitting machine, leveraging the stainless build to resist humid paper-mill environments.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X700SCA the Right Cylinder?
Choosing this bore means sizing against its neighbours: step down to a Ø16 for 100.5 N push, or up to a Ø25 for 245.3 N at 0.5 MPa. The 700 mm stroke is highly specialised; at this extension, the 8 mm rod is vulnerable to bending under side loads, so rigid guidance and a clevis mount are essential to prevent premature wear. The CA pivot helps accommodate minor misalignment.
Remember that fixed TPU bumpers only soften the end-of-stroke impact; they do not act as a brake. If air pressure drops or the valve centres, the piston will drift, so fit an external rod lock or pilot check valve for suspended loads. The integrated magnet supports CMSG, DMSG, and EMSG switches for precise end-position detection.
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 MI20X700SCA FAQ
At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it provides 219.8 N push and 184.7 N pull. The theoretical maximum force is 32 kgf at 1.0 MPa. The 700 mm stroke exceeds the 500 mm standard maximum for a Ø20 bore, making it a non-standard, made-to-order configuration.
Yes, the Ø20 bore uses the ISO 6432 mounting interface, so it drops into standard mini-cylinder brackets and clevises. This unit includes the -S magnet, allowing you to mount CMSG, DMSG, or EMSG switches directly for reed or electronic sensing.
