About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X130U
Delivering 157 N of push force at 0.5 MPa, this stainless-steel round-body mini cylinder handles compact automation with ease. The 20 mm bore features a 1/8" port and an M8x1.25 male rod thread, extending 130 mm on each cycle. Its riveted stainless barrel and rod shrug off mild corrosion, outperforming painted alternatives in damp environments. Fixed TPU bumper pads absorb end-of-stroke impact, while the U-style back cover provides a 90-degree port orientation for tight layouts.
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 SKU lacks the -S magnet, it cannot host CMSG, DMSG or EMSG sensors. The ISO 6432 mounting dimensions allow direct integration into standard mini-cylinder brackets and clevises.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X130U Is Used
Package Diverter
Pushes light cardboard cartons on a packaging line using 157 N of thrust, with the 90-degree U cover keeping air lines clear of the belt.
Textile Loom Guide
Shifts a yarn guide back and forth across a 130 mm path, relying on the stainless rod to endure humid manufacturing conditions.
Bin Gate Actuator
Opens and closes small hopper gates for plastic granules, where the fixed TPU bumpers quietly absorb the 8 kg gate impact.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X130U the Right Cylinder?
When sizing this 20 mm bore, compare your real load against the 131.9 N pull force at 0.5 MPa. If you need less power, the 16 mm variant offers 100.5 N; for heavier duty, the 25 mm bore pushes 245.3 N. This U-type rear cover suits 90-degree port routing, and you can pair the body with LB foot, FA flange, SDB pivot or TC trunnion hardware. Remember that fixed bumpers only decelerate the stroke end; they do not lock the rod.
If air pressure drops or the valve centres, the piston will drift and drop the load. To hold a vertical position securely, install an external rod lock or a pilot-operated check valve. The 130 mm stroke is well within the 500 mm maximum, but ensure side loads are minimized to prevent rod bending over the extension length.
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 MI20X130U FAQ
This 20 mm bore cylinder features a 1/8" port. It generates 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa.
No, this specific SKU lacks a magnet and cannot accept CMSG, DMSG or EMSG switches. You must order the -S variant for position sensing. The body uses ISO 6432 mounting dimensions for standard brackets.
