Airtac MI16-20 Stainless Steel Mini Cylinder MI16X55SU
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X55SU is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 55mm 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 MI16X55SU
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 55 mm stroke with a 1/8" port and M6x1.0 male rod thread. The rolled stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Fixed TPU bumper pads absorb the end-of-stroke impact, while the U-type back cover provides a 90-degree port orientation for tight machinery layouts.
Because the -S suffix denotes a built-in piston magnet, this unit is fully primed for CMSG, DMSG or EMSG position sensing. For practical sizing, plan for roughly 60 N of actual work at 0.5 MPa rather than the absolute maximum; vertically, it lifts about 5.1 kg with a 2:1 safety margin. The Ø16 bore adheres to ISO 6432 mounting dimensions, dropping smoothly into standard mini-cylinder brackets and clevises.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X55SU Is Used
Dial Indexer Tooling
Positions small clamps on a rotary dial table using 100.5 N of push force, relying on the 55 mm stroke to clear the part during unloading.
Carton Flap Folding
Deploys a folding arm at 90 degrees via the U-type back cover to tuck packaging flaps, handling the 5.1 kg vertical lift requirement with a 2:1 margin.
Lab Dispenser Gating
Actuates a reagent gate in a humid laboratory environment, where the stainless build prevents mild corrosion and the -S magnet tracks exact closure.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X55SU the Right Cylinder?
When sizing this 55 mm stroke actuator, stepping down to the Ø12 bore drops the 0.5 MPa push force to 56.5 N, whereas moving up to the Ø20 bore raises it to 157.0 N. If your process demands a held position during air loss or valve centering, remember that a plain cylinder drifts—the TPU pads only decelerate the stroke end, so an external rod lock or pilot-operated check valve is required for secure load holding. The 1/8" port and U-type 90-degree rear cover simplify plumbing in confined footprints.
At a 55 mm extension, keep an eye on side loading to avoid rod bending. The -S magnet allows seamless integration of reed or electronic sensors, and if higher cycle speeds cause excessive impact, the variable air cushion of the related MIC variant is a better choice than these fixed pads.
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 MI16X55SU FAQ
This Ø16 bore cylinder features a 1/8" port and a Ø6 mm rod. It generates 100.5 N push and 86.4 N pull at 0.5 MPa, 140.7 N push and 120.9 N pull at 0.7 MPa, with a theoretical maximum of 20.5 kgf at 1.0 MPa.
Yes, the -S magnet allows CMSG, DMSG and EMSG switches to track piston position. It has fixed TPU bumper pads that decelerate the stroke end, not an adjustable air cushion; for adjustable cushioning, look at the MIC variant.
