Airtac MI16-20 Stainless Steel Mini Cylinder MI20X10SU
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X10SU is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 10mm 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 MI20X10SU
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles short 10 mm strokes with precision. The riveted barrel and rod resist mild corrosion, outlasting painted alternatives in damp or washdown settings. Its 1/8" port feeds the Ø8 mm rod efficiently across the 30-800 mm/s speed range.
Because the 157 N rating is theoretical, plan for a real working load of about 94 N to ensure reliable operation. This translates to lifting roughly 8 kg vertically with a safe 2:1 margin. The built-in -S piston magnet supports CMSG, DMSG and EMSG switches for position sensing, while fixed TPU bumper pads absorb the stroke-end impact.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X10SU Is Used
Short-Stroke Part Clamping
Uses the 10 mm stroke to grip aluminium extrusions in machining fixtures, applying up to 94 N of safe clamping force without deforming the profile.
Package Diverter Gate
Pivots a routing flap on a packaging line, where the stainless build shrugs off washdown and the 8 kg vertical lift capacity moves light gates easily.
Electronic Component Ejection
Kicks PCBs or small plastic parts out of an assembly nest, relying on the -S magnet and DMSG sensors to confirm the 10 mm ejection movement.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X10SU the Right Cylinder?
For a 10 mm stroke, this Ø20 bore sits comfortably between the smaller Ø16 (100.5 N push) and the larger Ø25 (245.3 N push) at 0.5 MPa. The U-type back cover provides a 90-degree port orientation, easing plumbing in confined spaces. If your process loses air or the valve centres, the piston will drift; these bumpers only decelerate the end of travel rather than locking the load, so add an external rod lock or pilot check valve for holding. The ISO 6432 mounting interface ensures it drops directly into standard mini-cylinder brackets and clevises.
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 MI20X10SU 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. This Ø20 bore uses a 1/8" air port and an Ø8 mm piston rod.
No, the piston will drift if air is lost or the valve is centred. The fixed TPU bumper pads only decelerate the stroke end; they do not act as a brake. To maintain a vertical position, you must fit an external rod lock or a pilot-operated check valve.
