Airtac MI16-20 Stainless Steel Mini Cylinder MI20X75U
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X75U is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 75mm 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 MI20X75U
Delivering 157 N of push force at 0.5 MPa, the AirTAC MI20X75U is a double-acting round-body mini cylinder built for compact automation. Its stainless-steel barrel and piston rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. The 1/8" port feeds the 75 mm stroke, and the U-style back cover provides a 90-degree port orientation for tight machinery layouts.
This model relies on fixed TPU bumper pads to decelerate the stroke end rather than an adjustable air cushion. Because it lacks the -S suffix, this specific SKU cannot host CMSG, DMSG or EMSG magnetic switches. For actual work planning, budget for a safe working load of roughly 94 N, which equates to lifting about 8 kg vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X75U Is Used
Package Diverter Gate
Actuates a 90-degree routing flap on a packaging line, using the U-style rear cover to fit neatly into the conveyor frame and push light cartons with 157 N of force.
Textile Loom Tensioner
Adjusts the tension arm on a weaving machine where ambient humidity makes the stainless-steel rod and barrel superior to standard steel bodies for long-term corrosion resistance.
Bin Lid Opener
Lifts a hinged hopper lid weighing about 8 kg vertically, operating safely within the 2:1 load margin derived from the 0.5 MPa push rating.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X75U the Right Cylinder?
When sizing this 20 mm bore, compare it against its neighbours: the 16 mm bore yields 100.5 N of push at 0.5 MPa, while the 25 mm bore steps up to 245.3 N. Choose the MI20X75U when your payload sits in that middle ground, requiring roughly 94 N of real working force. The 75 mm stroke is well within the 500 mm maximum, keeping rod bending stress low.
Remember that a standard double-acting cylinder drifts when air is lost or the valve is centred, as the TPU bumpers only soften the end of travel and act as neither a lock nor a brake. To suspend a load safely, integrate an external rod lock or a pilot-operated check valve. Furthermore, since this SKU has no internal magnet, position sensing is impossible without upgrading to the -S variant.
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 MI20X75U 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 lacks an internal magnet so it cannot accept CMSG, DMSG or EMSG switches. You would need the -S variant for sensing. It uses the ISO 6432 mounting interface for standard brackets and features fixed TPU bumper pads rather than an adjustable air cushion.
