Airtac MI16-20 Stainless Steel Mini Cylinder MI20X150SU
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X150SU is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 150mm 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 MI20X150SU
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 150 mm stroke with a 1/8" port and an M8x1.25 male rod thread. The rolled and riveted stainless barrel shrugs off mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. Because the bore is Ø20, it conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets and clevises.
The built-in piston magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing, while the U back cover provides a 90-degree mounting interface. Fixed TPU bumper pads absorb the impact at stroke extremes without adding bulk. For practical sizing, plan for a safe working load of about 94 N, which means it can comfortably lift an 8 kg part vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X150SU Is Used
Package Diverter Gate
Pushes lightweight cardboard cartons on a packaging line using 157 N of thrust, with the U cover allowing a compact 90-degree hinge mount.
Lab Sample Ejection
Ejects 8 kg test tube racks from a centrifuge, where the stainless steel barrel resists chemical splashes and the -S magnet confirms ejection.
Tote Positioning Stop
Acts as a 150 mm stop pin for plastic totes on a gravity conveyor, relying on fixed TPU pads to soften the repetitive end-of-stroke impact.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X150SU the Right Cylinder?
When sizing this 150 mm stroke actuator, compare it against its neighbours: the smaller Ø16 bore yields 100.5 N of push at 0.5 MPa, while the larger Ø25 bore generates 245.3 N. This Ø20 model hits a solid middle ground for 8 kg vertical lifts. If your valve centres or air supply drops, the piston will drift and cannot hold position; the bumpers only decelerate the end of travel, so add an external pilot check valve if you need to lock a load. The 150 mm stroke is well within the 500 mm maximum, but keep side-loads minimal to avoid rod bending.
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 MI20X150SU FAQ
This Ø20 mm bore cylinder uses a 1/8" air port. 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 -S suffix means it has a piston magnet ready for CMSG, DMSG or EMSG switches. However, it does not hold position if air is lost; the piston drifts, so you need a pilot check valve for load holding.
