Airtac MI16-20 Stainless Steel Mini Cylinder MI16X25R
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X25R is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 25mm 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 MI16X25R
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact 25 mm strokes with a 1/8 inch port. The Ø16 bore uses standard ISO 6432 mounting dimensions, so it drops directly into common mini-cylinder brackets and clevises. Its fixed TPU bumper pads absorb end-of-stroke impact without needing adjustment.
The riveted stainless barrel and rod resist mild corrosion, making it superior to painted alternatives in damp environments. Plan for about 60 N of actual work at 0.5 MPa, which means it can safely lift a 5.1 kg part vertically with a 2:1 safety margin. 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 MI16X25R Is Used
Ejector Gate
Knocks small plastic parts out of an injection mould tool using the 25 mm stroke and 100.5 N push force.
Sorter Diverter
Flicks lightweight cardboard cartons on a packaging line where the stainless body resists daily washdown.
Clamp Arm
Holds a thin metal workpiece in a machining fixture using the compact 16 mm bore and M6x1.0 rod thread.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X25R the Right Cylinder?
When sizing this actuator, the 25 mm stroke is ideal for very short movements. If you need less force, the Ø12 bore provides 56.5 N of push at 0.5 MPa; stepping up to the Ø20 bore yields 157.0 N. The R back cover supplies an axial-in port orientation, which helps when side space is tight. You can mount it using LB foot, FA flange, SDB pivot or TC trunnion hardware.
Remember that a standard double-acting cylinder drifts if air pressure drops or the valve is centred, as the TPU pads only soften the stroke end rather than locking the rod. To hold a vertical load securely, add an external rod lock or a pilot-operated check valve. For position feedback, select the -S magnet version instead of this base model.
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 MI16X25R FAQ
At 0.5 MPa it provides 100.5 N push and 86.4 N pull. At 0.7 MPa it provides 140.7 N push and 120.9 N pull. The theoretical maximum force is 20.5 kgf at 1.0 MPa. The air port is 1/8 inch.
Yes, the Ø16 bore follows ISO 6432 mounting dimensions for easy bracket fitment. However, because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG switches. You must choose the -S variant for position sensing.
