Airtac MI16-20 Stainless Steel Mini Cylinder MI20X65U
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X65U 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 MI20X65U
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation with ease. The Ø20 mm bore features a 1/8" port and an M8x1.25 male rod thread. Its riveted stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. Fixed TPU bumper pads absorb stroke-end impact to protect your mechanism.
Because the piston generates 157 N at 0.5 MPa, you can plan for a safe working load of roughly 94 N of real work. That translates to lifting about 8 kg vertically with a 2:1 safety margin. The U back cover provides a 90-degree port orientation for tight spatial constraints. Note that this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG or EMSG position switches without upgrading to the -S variant.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X65U Is Used
Package Sorting Diverter
Pushes lightweight cardboard cartons on a packaging line using its 157 N thrust and 65 mm travel distance.
Textile Loom Tensioner
Maintains thread tension in humid textile facilities where the stainless steel barrel prevents mild corrosion.
Small Part Ejector
Ejects moulded plastic components from a press, utilising the 90-degree U back cover to route air cleanly in a tight cell.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X65U the Right Cylinder?
When sizing this 65 mm stroke model, compare it against its neighbours: the smaller Ø16 bore yields 100.5 N of push at 0.5 MPa, while the larger Ø25 bore provides 245.3 N. Choose the Ø20 to hit the sweet spot for medium-duty sorting tasks. If your mechanism loses air or the valve centres, this cylinder will drift and cannot hold position—the fixed bumpers only decelerate the end of travel, so add an external rod lock or pilot check valve for suspended loads. The ISO 6432 mounting interface means it drops directly into standard mini-cylinder brackets and clevises. For long strokes near the 500 mm maximum, watch out for rod bending and side-loading forces.
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 MI20X65U FAQ
At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it provides 219.8 N push and 184.7 N pull. The theoretical maximum force is 32 kgf at 1.0 MPa. The air port size is 1/8".
No, this specific SKU does not have a magnet and cannot accept CMSG, DMSG or EMSG switches. You must select the -S magnet variant for position sensing. It uses the ISO 6432 mounting interface and fixed TPU bumper pads rather than adjustable cushions.
