Airtac MI16-20 Stainless Steel Mini Cylinder MI20X30SR
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X30SR is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 30mm 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 MI20X30SR
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles short 30 mm strokes with precision. The riveted barrel and rod resist mild corrosion, making it superior to painted alternatives in damp environments. Its compact 20 mm bore uses a 1/8" port and an R axial-in rear cover for tidy routing.
The built-in piston magnet supports CMSG, DMSG and EMSG switches for exact position detection. With fixed TPU bumper pads softening stroke-end impacts, it operates smoothly at 30-800 mm/s. Plan for roughly 94 N of actual work at 0.5 MPa, which means it can vertically lift about 8 kg with a safe 2:1 margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X30SR Is Used
Clamp Actuation
Drives short-stroke clamping jaws on small machining fixtures, applying up to 157 N of push force to secure light metal components during milling.
Flap Folding
Folds carton flaps on compact packaging lines where the 30 mm stroke provides just enough travel without excessive rod overhang.
Gate Diverting
Pivots small diverter gates on conveyor systems, using the built-in magnet to confirm gate position via DMSG sensors in washdown zones.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X30SR the Right Cylinder?
When sizing this 20 mm bore, stepping down to the 16 mm variant drops the push force to 100.5 N, while moving up to the 25 mm bore increases it to 245.3 N at 0.5 MPa. This model includes the -S magnet for sensing and the R back cover for axial porting. Mounting options include LB foot, FA flange, SDB pivot and TC trunnion brackets.
Because the 30 mm stroke is very short, rod bending under side loads is minimal, but always guide the load rigidly. Note that air pressure alone will not hold a load if the valve is centred or supply drops, as the piston will drift; add a pilot-operated check valve or external rod lock if you need strict position holding.
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 MI20X30SR 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 of 32 kgf at 1.0 MPa.
Yes, the 20 mm bore uses the ISO 6432 mini-cylinder mounting interface, dropping directly into standard brackets and clevises. It relies on fixed TPU bumper pads to decelerate at stroke end, but these do not lock the piston; you need an external rod lock or pilot check valve to hold a load vertically.
