Airtac MI16-20 Stainless Steel Mini Cylinder MI20X225UTC
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X225UTC is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 225mm 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 MI20X225UTC
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 225 mm stroke with ease. The Ø20 mm bore uses a 1/8" air port and an M8x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Fixed TPU bumper pads absorb the impact at stroke ends, decelerating the motion smoothly.
For practical sizing, plan for a working load of roughly 94 N, which is about 60% of the 0.5 MPa rating. This translates to lifting an 8 kg part vertically with a safe 2:1 margin. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches. The U back cover provides a 90-degree port orientation, while the included TC trunnion supports pivot mounting.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X225UTC Is Used
Package Diverter Gate
Actuates a routing flap on a packaging line, using its 225 mm stroke to shift cardboard boxes between sorting lanes.
Parts Elevator Lowering
Lowers lightweight plastic trays into a filling station, safely managing the 8 kg vertical load within a 2:1 safety margin.
Textile Loom Tensioner
Adjusts the tension arm on a weaving machine, where the stainless construction withstands humid manufacturing environments.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X225UTC the Right Cylinder?
When sizing this unit, note the smaller Ø16 bore generates 100.5 N of push at 0.5 MPa, whereas the larger Ø25 bore yields 245.3 N. This model sits comfortably in the middle for medium-duty tasks. Keep in mind that a plain cylinder drifts if air pressure drops or the valve is centred; the bumpers only soften the end of travel and will not lock the load. For vertical applications requiring position holding, you should add an external rod lock or a pilot-operated check valve.
The 225 mm stroke is well within the 500 mm maximum standard stroke for this bore, meaning no made-to-order modifications are required. However, at this extended length, be cautious of side loads. Properly align the TC trunnion mount to prevent rod bending and premature seal wear during operation.
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 MI20X225UTC FAQ
This Ø20 mm bore cylinder features a 1/8" air port and an M8x1.25 male rod thread. 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 force of 32 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet, so it cannot accept CMSG, DMSG or EMSG magnetic switches. You would need the -S variant for sensing. It uses the ISO 6432 mounting interface and includes a TC trunnion for pivot mounting.
