Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100SCASDB
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100SCASDB is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 100mm 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 MI20X100SCASDB
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 100 mm stroke with a Ø8 mm piston rod. The riveted barrel and rod shrug off mild corrosion, making it superior to painted alternatives in damp or washdown settings. Its 1/8" port feeds air to extend and retract the rod at 30-800 mm/s.
The built-in -S magnet supports CMSG, DMSG and EMSG switches for position sensing, while fixed TPU bumper pads absorb end-of-stroke impacts. For practical sizing, plan for roughly 94 N of actual work at 0.5 MPa, which means it can comfortably lift about 8 kg vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100SCASDB Is Used
Package Diverter
Pushes light cardboard cartons on a packaging line using the 100 mm stroke, relying on the stainless body to resist humidity in washdown zones.
Textile Loom Tensioner
Maintains thread tension via the CA clevis, applying up to 94 N of working force while the SDB pivot block absorbs lateral shaft movement.
Lab Sample Ejector
Ejects processed vials from a testing carousel, using the -S magnet with a DMSG sensor to confirm the full 100 mm retraction before the next cycle.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100SCASDB the Right Cylinder?
When sizing this 20 mm bore, the smaller 16 mm variant offers 100.5 N push, whereas the larger 25 mm bore provides 245.3 N at 0.5 MPa. This model includes a CA pivot clevis back cover and an SDB pivot-block mounting accessory. Because the ISO 6432 mounting interface matches standard mini-cylinder brackets, integration into existing assemblies is straightforward.
Remember that a standard cylinder drifts if air pressure drops or the valve centers; the bumpers only decelerate the stroke end and do not act as a brake. To suspend a load safely, install an external rod lock or a pilot-operated check valve. For high-speed cycles demanding adjustable air cushioning, consider the MIC variant instead.
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 MI20X100SCASDB FAQ
This 20 mm bore cylinder features a 1/8" port and an M8x1.25 male rod thread. 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 force of 32 kgf at 1.0 MPa.
No, the piston will drift if air pressure is lost or the valve is centered. The fixed TPU bumper pads only decelerate the rod near the stroke end; they do not lock the position. Use an external rod lock or pilot check valve for suspended loads.
