About the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X225U
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles mid-range automation tasks with ease. The 16 mm bore uses a 1/8" port and a 6 mm piston rod with an M6x1.0 male thread. Its round-body, riveted construction shrinks the footprint while the fixed TPU bumper pads absorb end-of-stroke impacts. Because there is no magnet on this SKU, it cannot host position sensors; adding the -S variant enables CMSG, DMSG or EMSG switches.
The stainless barrel and rod resist mild corrosion, giving it an edge over painted alternatives in damp or washdown environments. At 0.5 MPa you can plan for a safe working load of about 60 N, which equates to lifting roughly 5.1 kg vertically with a 2:1 safety margin. The U-style rear cover provides a 90-degree mounting interface, making it easy to integrate into tight machinery corners.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X225U Is Used
Package Diverting Gate
Actuates a lightweight routing flap on a packaging line, using the 100.5 N thrust to push corrugated boxes onto a secondary belt.
Textile Loom Tensioner
Adjusts a yarn guide bar in humid textile facilities, leveraging the stainless steel rod to withstand fibrous dust and moisture.
Bin Lid Automation
Opens and closes access hatches on storage bins, where the 90-degree U rear cover provides a compact pivot point.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X225U the Right Cylinder?
This 225 mm stroke sits well within the 500 mm maximum for the 16 mm bore, though the extended length demands attention to side loading to prevent rod bending. If you need less force, the 12 mm bore offers 56.5 N push at 0.5 MPa; stepping up to the 20 mm bore provides 157.0 N. Remember that a plain cylinder drifts when air is lost or a valve is centered, so install an external rod lock or pilot check valve if you must hold a vertical load. The U back cover suits 90-degree pivot mounts, and you can pair it with LB foot, FA flange, SDB pivot or TC trunnion hardware.
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 MI16X225U FAQ
This 16 mm bore cylinder features a 1/8" port and generates 100.5 N push / 86.4 N pull at 0.5 MPa, and 140.7 N push / 120.9 N pull at 0.7 MPa. The theoretical maximum force is 20.5 kgf at 1.0 MPa.
It uses the ISO 6432 mounting interface, so it drops into standard mini-cylinder brackets and clevises. However, because this specific SKU lacks a magnet, it cannot accept CMSG, DMSG or EMSG sensors; you would need the -S variant for position detection.
