About the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X275SU
Generating 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles long 275 mm strokes with a compact riveted round body. The Ø16 bore operates on a 1/8" port and features a built-in magnet for CMSG, DMSG or EMSG sensors. Its stainless barrel and rod resist mild corrosion, offering a real advantage over painted alternatives in damp or washdown environments.
Because it conforms to ISO 6432 mounting dimensions, the unit drops directly into standard mini-cylinder brackets and clevises. For practical sizing, plan for about 60 N of real work at 0.5 MPa, which means it lifts roughly 5.1 kg vertically with a 2:1 safety margin. Fixed TPU bumper pads absorb the impact at stroke ends, and the rear U cover provides a 90-degree port orientation for tight machinery layouts.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X275SU Is Used
Package Diverting
Pushes light cartons on a packaging line using its 275 mm stroke, relying on the 60 N safe working load to re-route goods without stalling.
Textile Loom Tensioning
Maintains thread tension in humid textile manufacturing, where the stainless steel rod prevents mild corrosion and the U cover eases hose routing.
Lab Sample Ejection
Ejects processed sample trays from testing equipment, using the -S magnet with a DMSG sensor to confirm full extension before the next cycle.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X275SU the Right Cylinder?
When sizing this 275 mm stroke model, compare it against adjacent bores: the smaller Ø12 generates 56.5 N push at 0.5 MPa, while the larger Ø20 provides 157.0 N. If your application requires true position holding on air loss, note that this standard cylinder will drift when the valve is centred, as the TPU pads only decelerate the stroke end rather than locking the rod. You would need an external rod lock or pilot check valve for secure load holding. The built-in -S magnet enables position sensing, and the 90-degree U rear cover helps route plumbing neatly in confined spaces. For a 275 mm extension, ensure your mounting arrangement minimizes side loading to prevent 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 MI16X275SU FAQ
This Ø16 bore cylinder uses a 1/8" port. 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 force of 20.5 kgf at 1.0 MPa.
No, it uses fixed TPU bumper pads to decelerate the piston at the stroke ends. For adjustable pneumatic cushioning, you would need the MIC variant. This model also includes a -S magnet for CMSG, DMSG or EMSG sensors.
