Airtac MI16-20 Stainless Steel Mini Cylinder MI16X170U
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X170U is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 170mm 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 MI16X170U
Generating 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 170 mm stroke with a 1/8" port. The Ø6 mm piston rod uses an M6x1.0 male thread, while the U back cover provides a 90-degree port orientation for tight machinery layouts. Its riveted stainless barrel shrugs off mild corrosion, outperforming painted alternatives in damp or washdown environments.
Because fixed TPU bumper pads only decelerate the stroke end rather than acting as an adjustable cushion, you should plan for a real working load of about 60 N. This equates to lifting roughly 5.1 kg vertically with a safe 2:1 margin. The unit lacks a magnet, so it cannot accept CMSG, DMSG or EMSG sensors without switching to an -S variant.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X170U Is Used
Package Diverter Arm
Actuates a 170 mm swing gate to sort lightweight cardboard cartons on a packaging line, utilising the 100.5 N push force to overcome guide friction.
Textile Loom Tensioner
Moves a yarn guide bar in damp textile manufacturing, where the stainless-steel barrel prevents mild corrosion from ambient humidity.
Small Parts Ejector
Pushes machined plastic fittings out of a CNC station, relying on the 90-degree U back cover to keep the 1/8" air line clear of the tool head.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X170U the Right Cylinder?
Sizing against its neighbours, the Ø16 bore pushes 100.5 N at 0.5 MPa, sitting neatly between the smaller Ø12 at 56.5 N and the larger Ø20 at 157.0 N. If your application demands position feedback, note that this specific SKU has no magnet and therefore cannot host a reed switch. You would need to specify the -S option to enable CMSG, DMSG or EMSG sensors.
The 170 mm stroke is well within the 500 mm maximum standard stroke for this bore, but at this length you must account for rod bending under side loads. Furthermore, this plain cylinder will drift if air is lost or the valve is centred—the TPU bumpers only soften the end of travel and do not function as a brake. To suspend a load safely, fit an external rod lock or a pilot-operated check valve.
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 MI16X170U FAQ
This Ø16 mm bore cylinder features a 1/8" port. It generates 100.5 N push and 86.4 N pull at 0.5 MPa, increasing to 140.7 N push and 120.9 N pull at 0.7 MPa. The theoretical maximum force is 20.5 kgf at 1.0 MPa.
Yes, the Ø16 bore uses the ISO 6432 mounting interface, so it drops directly into standard mini-cylinder foot, flange or trunnion brackets. However, this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG or EMSG sensors; you must specify an -S variant for position sensing.
