Airtac MI16-20 Stainless Steel Mini Cylinder MI20X75SCA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X75SCA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 75mm 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 MI20X75SCA
Delivering 157 N of push force at 0.5 MPa, this AirTAC MI20X75SCA is a double-acting round-body mini cylinder built from a stainless-steel barrel and rod. The riveted construction shrinks the footprint while resisting mild corrosion, making it highly suitable for damp production lines or washdown zones where painted steel degrades. Its 1/8" port feeds the 8 mm rod to move loads quickly across a 75 mm travel range.
The built-in piston magnet allows direct mounting of CMSG, DMSG or EMSG sensors for position confirmation. Because it conforms to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets without custom machining. Plan for a safe working load of roughly 94 N, which lets you lift about 8 kg vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X75SCA Is Used
Package Diverter Gate
Pivots a routing flap on a packaging conveyor to sort 8 kg cartons, utilising the 157 N push force and CA clevis for smooth articulation.
Textile Loom Tensioner
Adjusts a yarn guide bar through a 75 mm travel in a humid textile facility, relying on the stainless rod to resist moisture corrosion.
Small Press Ejector
Kicks stamped metal blanks out of a die using the 219.8 N push force available at 0.7 MPa, with DMSG sensors confirming the ejection stroke.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X75SCA the Right Cylinder?
When sizing this 20 mm bore, compare it directly against its neighbours: a 16 mm bore yields 100.5 N of push at 0.5 MPa, while stepping up to a 25 mm bore provides 245.3 N. This model includes a CA rear pivot clevis, ideal for articulating linkages, and the -S magnet enables electronic or reed switching. If your mechanism relies on the cylinder to maintain elevation during an air loss or valve centre state, add an external rod lock or pilot check valve, as the piston will drift without air pressure.
At a 75 mm stroke, side loading is less severe than on longer 500 mm variants, but you should still ensure the rod end aligns with the load to prevent premature seal wear. The fixed TPU bumper pads absorb the stroke-end impact, operating effectively between 30 and 800 mm/s.
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 MI20X75SCA FAQ
This 20 mm bore cylinder features a 1/8" port and an 8 mm rod. It generates 157 N push and 131.9 N pull at 0.5 MPa, increasing to 219.8 N push and 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa.
No, the piston will drift if air pressure is lost or the valve is centred. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. For vertical loads, install an external rod lock or pilot-operated check valve.
