About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X150U
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 150 mm stroke with a 1/8 inch air port. The Ø20 mm bore uses standard ISO 6432 mounting dimensions, dropping directly into common mini-cylinder brackets and clevises for easy design integration. Its riveted stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp processing areas.
Fixed TPU bumper pads absorb the impact at stroke extremes, though they decelerate rather than provide adjustable cushioning. Plan for roughly 94 N of actual work at 0.5 MPa to maintain a safe margin, which translates to lifting about 8 kg vertically. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X150U Is Used
Package Diverter Gate
Pushes lightweight cardboard cartons on a packaging line using 157 N of force, with the 150 mm stroke providing full lane separation.
Textile Loom Tensioner
Adjusts yarn guide arms in humid textile facilities where the stainless steel barrel prevents mild corrosion from ambient moisture.
Bin Lid Actuator
Opens and closes hinged access covers on material bins, lifting roughly 8 kg lids vertically through the 150 mm travel distance.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X150U the Right Cylinder?
When sizing this 150 mm stroke model, verify the 157 N push at 0.5 MPa is sufficient; if more power is needed, the Ø25 bore yields 245 N, while stepping down to the Ø16 bore offers 100.5 N for lighter duty. The U-type back cover provides a 90-degree port orientation, easing hose routing in tight spaces. For mounting flexibility, you can utilize LB foot brackets, FA flanges, SDB pivot blocks or TC trunnions.
Remember that air pressure alone does not secure the piston if supply drops or the valve centers, as the rod will drift and the TPU pads only soften the end stops. To hold a vertical load safely, incorporate an external rod lock or a pilot-operated check valve. Additionally, the 150 mm stroke demands attention to side loading, so ensure proper alignment to prevent premature rod bending and seal wear.
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 MI20X150U FAQ
This double-acting cylinder features a 1/8 inch air port and generates 157 N push / 131.9 N pull at 0.5 MPa, and 219.8 N push / 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet, so it cannot accept CMSG, DMSG or EMSG switches. You would need the -S variant for position sensing, while this model relies on its fixed TPU bumper pads for end-of-stroke deceleration.
