Airtac MI16-20 Stainless Steel Mini Cylinder MI20X600SU
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X600SU is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 600mm 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 MI20X600SU
Generating 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles long 600 mm traverses. Because 600 mm exceeds the 500 mm standard limit for this Ø20 bore, it is produced as a non-standard, made-to-order unit. The stainless barrel and rod shrug off mild corrosion, giving it an edge over painted alternatives in damp or washdown settings. It features a 1/8" port and an M8x1.25 male rod thread.
The riveted body keeps the actuator compact, while fixed TPU bumper pads absorb impact at the stroke extremes. Equipped with a U 90-degree back cover and a piston magnet, it supports CMSG, DMSG and EMSG switches. Plan for roughly 94 N of actual work at 0.5 MPa, which means it can safely lift about 8 kg vertically against gravity.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X600SU Is Used
Long-Reach Divertor
Pushes packages across a wide sorting belt using the full 600 mm extension, relying on the 157 N push at 0.5 MPa to nudge cartons smoothly.
Vertical Lift Gate
Raises an 8 kg access panel in a humid distribution centre, where the stainless construction prevents mild corrosion from ambient moisture.
Textile Beam Shift
Translates a winding beam along a 600 mm axis, using the U 90-degree back cover to keep pneumatic plumbing neatly oriented alongside the machine frame.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X600SU the Right Cylinder?
If 131.9 N of pull at 0.5 MPa is insufficient, step up to the Ø25 bore for 206.1 N; if your load is lighter, the Ø16 bore provides 86.4 N of pull. This SKU includes the -S magnet for position sensing and a U rear cover for 90-degree port orientation. Be aware that a 600 mm stroke on an Ø8 rod invites side-load bending, so guide the load carefully.
Venting the valve or losing air pressure lets the piston drift, as the TPU pads only soften the end-of-stroke impact rather than locking the rod. To suspend a load safely mid-stroke, fit an external rod lock or a pilot-operated check valve.
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 MI20X600SU FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N. At 0.7 MPa it pushes 219.8 N and pulls 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa. The air port is 1/8" and the male rod thread is M8x1.25.
No, it relies on fixed TPU bumper pads to decelerate at the ends, not an adjustable air cushion. It also does not hold position if air is lost; the piston will drift. For holding, use an external rod lock or pilot check valve. It conforms to ISO 6432 mounting dimensions and includes a magnet for CMSG/DMSG/EMSG sensors.
