Airtac MI16-20 Stainless Steel Mini Cylinder MI16X280SU
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X280SU is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 280mm 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 MI16X280SU
Generating 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 280 mm stroke with ease. The riveted barrel and piston rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp production areas. Because the bore is Ø16, it uses the ISO 6432 mounting interface, so it drops directly into standard mini-cylinder brackets and clevises.
Plan for roughly 60 N of actual work at 0.5 MPa rather than the absolute maximum, which translates to lifting about 5.1 kg vertically with a 2:1 safety margin. The built-in magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing, while the U back cover provides a 90-degree port and mounting orientation. Fixed TPU bumper pads absorb the impact at stroke end, and the 1/8" port ensures rapid airflow for speeds up to 800 mm/s.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X280SU Is Used
Package Diverter Gate
Pushes lightweight cardboard cartons on a packaging line using 100.5 N of thrust, with the U cover allowing a tidy 90-degree pivot mount alongside the belt.
Textile Loom Tensioner
Maintains yarn tension in a humid textile facility where the stainless steel barrel resists mild corrosion and the 280 mm stroke provides ample adjustment range.
Lab Sample Ejector
Ejects processed test tubes from a centrifuge, relying on the -S magnet and an EMSG sensor to confirm the full 280 mm retraction before the next cycle begins.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X280SU the Right Cylinder?
When sizing this 280 mm stroke unit, consider the neighbouring bores: stepping down to the Ø12 yields 56.5 N of push at 0.5 MPa, while moving up to the Ø20 provides 157.0 N. If your process drops air pressure or the valve centres, this cylinder will drift and cannot hold position—the TPU pads only decelerate the end of travel, so add an external rod lock or pilot check valve for suspended loads. The 280 mm stroke is well within the 500 mm maximum, though at this length you should carefully manage side loading to prevent rod bending. The -S magnet pairs directly with CMSG, DMSG or EMSG sensors, and the U rear cover simplifies 90-degree mounting layouts.
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 MI16X280SU FAQ
This Ø16 bore cylinder has a 1/8" air port and an M6x1.0 male rod thread. 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.
No, the piston will drift if air is lost or the valve is centred. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. To suspend a load safely, install an external rod lock or a pilot-operated check valve.
