Airtac MI16-20 Stainless Steel Mini Cylinder MI20X65SU
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X65SU is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 65mm 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 MI20X65SU
Delivering 157 N of push force at 0.5 MPa, the AirTAC MI20X65SU is a double-acting round-body mini cylinder built for demanding 20 mm bore tasks. The stainless-steel barrel and rod shrug off mild corrosion, giving it a real edge over painted steel in damp or washdown environments. Its 65 mm stroke is driven by a 1/8" port, while fixed TPU bumper pads absorb the impact at stroke end. Because this bore falls within the Ø8-Ø25 range, it uses the ISO 6432 mounting interface, dropping directly into standard mini-cylinder brackets and clevises.
For real-world sizing, plan for about 94 N of actual work at 0.5 MPa rather than the absolute maximum rating. That translates to lifting an 8 kg part vertically with a safe 2:1 margin. The built-in piston magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing, and the rear U cover provides a 90-degree port and mounting orientation for tight spaces.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X65SU Is Used
Package Diverter Arm
Pushes lightweight cardboard cartons on a packaging line using 157 N of thrust, where the stainless build survives humid packing rooms.
Textile Loom Tensioner
Modulates thread tension via the 65 mm stroke, relying on the 90-degree U cover to fit neatly within a compact weaving machine frame.
Lab Sample Ejector
Ejects processed vials from a testing carousel, lifting roughly 8 kg of vertical fixture mass safely with its 2:1 lifting margin.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X65SU the Right Cylinder?
When sizing this 20 mm bore actuator, check both neighbours: the smaller Ø16 generates 100.5 N of push at 0.5 MPa, while the larger Ø25 steps up to 245.3 N. Choose the MI20X65SU when your payload sits in that middle ground. If your mechanism must hold a vertical load when air is removed or the valve is centred, remember this cylinder will drift; the TPU bumpers only decelerate the stroke end and act as neither a lock nor a brake. You will need an external rod lock or a pilot-operated check valve to hold position.
The 65 mm stroke is well within the 500 mm maximum, keeping rod bending stress low. This SKU includes the U back cover for 90-degree mounting and the -S magnet for sensors. If you need adjustable end-cushioning for high-speed cycles, look at the MIC variant instead of this fixed-bumper base model.
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 MI20X65SU 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. Air is supplied through a 1/8" port.
Yes, the -S suffix means it has a built-in piston magnet for CMSG, DMSG and EMSG switches. The U back cover provides a 90-degree mounting and port orientation. It uses the ISO 6432 mounting interface for standard brackets.
