Airtac MI16-20 Stainless Steel Mini Cylinder MI20X25CM
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X25CM is a genuine double acting round-body mini air cylinder with a Ø20mm 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 MI20X25CM
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles short 25 mm strokes with a compact footprint. The riveted barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. Its 1/8" port and M8x1.25 male rod thread are sized directly for the Ø20 bore.
Because it conforms to ISO 6432 mounting dimensions, the body drops straight into standard mini-cylinder brackets and clevises. The CM round rear cover keeps the profile smooth for tight spaces. For actual work, plan for roughly 94 N of usable load at 0.5 MPa, which means it can comfortably lift about 8 kg vertically with a 2:1 safety margin. Fixed TPU bumper pads absorb the stroke-end impact.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X25CM Is Used
Clamp Actuation
Drives short-stroke clamping jaws on small CNC fixtures, using its 157 N push force to secure light aluminium parts during machining.
Flap Folding
Folds carton flaps on compact packaging lines where the 25 mm stroke and smooth CM round rear cover fit into tight transfer gaps.
Lab Dispenser
Actuates a precision fluid dispensing valve in a damp laboratory setting, relying on the stainless-steel rod to resist mild chemical corrosion.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X25CM the Right Cylinder?
When sizing this actuator, the Ø16 bore below offers 100.5 N push at 0.5 MPa, while the Ø25 above jumps to 245.3 N, making the Ø20 the sweet spot for mid-range tasks. This specific SKU lacks the -S magnet, so it cannot host CMSG, DMSG or EMSG sensors; choose an -S variant if you need position detection. You can mount it via LB foot, FA flange, SDB pivot or TC trunnion hardware.
Remember that a standard cylinder drifts if air pressure drops or the valve is centred, as the TPU pads only decelerate the end of travel rather than locking the rod. To suspend a load safely, fit an external rod lock or a pilot-operated check valve. The short 25 mm stroke also keeps rod bending stress minimal even under slight side loads.
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 MI20X25CM FAQ
This Ø20 mm bore cylinder features a 1/8" 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 of 32 kgf at 1.0 MPa.
No, this SKU does not include a magnet. You must select an -S variant to use CMSG, DMSG or EMSG switches. The unit relies on fixed TPU bumper pads for end-of-stroke deceleration and uses standard ISO 6432 mounting dimensions.
