Airtac MI16-20 Stainless Steel Mini Cylinder MI20X110SCA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X110SCA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 110mm 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 MI20X110SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles 110 mm of travel with ease. The Ø20 mm bore uses a 1/8 inch 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 areas. The riveted body keeps the unit compact while fixed TPU bumper pads absorb impact at the stroke ends.
Because the 157 N rating is theoretical, plan for a safe working load of about 94 N of real work at 0.5 MPa. Vertically, that equates to lifting an 8 kg part with a 2:1 safety margin. The built-in magnet supports CMSG, DMSG and EMSG switches, and the CA rear pivot cover provides a robust clevis mount for articulated linkages.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X110SCA Is Used
Diverter Gate Actuation
Pushes a routing flap on a packaging line using the 157 N thrust, with the CA clevis accommodating the pivot arc during the 110 mm travel.
Lab Sample Ejection
Ejects processed sample trays from a tester, leveraging the stainless build to withstand humidity and occasional chemical splashes.
Carton Flap Folding
Folds corrugated cardboard flaps prior to sealing, where the 94 N safe working load easily overcomes board resistance without crushing the carton.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X110SCA the Right Cylinder?
When sizing this unit, the smaller Ø16 bore offers 100.5 N of push at 0.5 MPa, while the larger Ø25 bore steps up to 245.3 N if your payload exceeds the 94 N safe working load. The 110 mm stroke is well within the 500 mm maximum standard stroke for this bore, so no made-to-order sizing is required. The included -S magnet enables position sensing, and the CA back cover suits pivoting loads.
Remember that a standard cylinder drifts when air is lost or the valve is centred; the TPU bumpers only decelerate the stroke end and do not act as a lock. To suspend a vertical load safely, install an external rod lock or a pilot-operated check valve. For high-speed cycles requiring adjustable end-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 MI20X110SCA FAQ
This Ø20 mm bore cylinder features a 1/8 inch 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 base MI uses fixed TPU bumper pads to decelerate at the stroke end, not an adjustable air cushion. Additionally, it will drift if air is lost or the valve is centred; you must use an external rod lock or pilot check valve to hold a suspended load.
