About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X20SCM
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles short 20 mm strokes with precision. The riveted construction uses a stainless barrel and rod to resist mild corrosion, giving it a real edge over painted alternatives in damp washdown zones. Because the bore is Ø20, it conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets and clevises for easy design integration.
The rear CM round cover helps streamline port and mounting orientation in tight spaces. Equipped with a built-in piston magnet, this unit supports CMSG, DMSG and EMSG switches for position sensing. Fixed TPU bumper pads absorb the impact at stroke end to protect the mechanism. For real-world tasks, plan for roughly 94 N of usable work at 0.5 MPa, which means it can safely lift about 8 kg vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X20SCM Is Used
Clamp Actuation
Drives short-stroke clamping jaws on small CNC machining fixtures, using its 157 N push force to secure light aluminium workpieces during milling.
Flap Folding
Folds cardboard flaps on compact packaging lines where the 20 mm stroke and 8 kg vertical lift capacity are ideal for rapid, repetitive motions.
Lab Dispenser
Actuates a precision fluid dispensing valve in laboratory automation, relying on the stainless build to withstand chemical splashes and daily wipe-downs.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X20SCM the Right Cylinder?
When sizing this 20 mm bore, the smaller Ø16 generates 100.5 N of push at 0.5 MPa, while the larger Ø25 provides 245.3 N, letting you step up or down if the 157 N output misses the target. The 1/8" port and M8x1.25 male rod thread are fixed by the bore size. This SKU includes the -S magnet for sensing and the CM round back cover. Keep in mind that a plain cylinder drifts if air pressure drops or the valve is centered; the TPU bumpers only decelerate the stroke end and do not act as a brake, so add an external rod lock or pilot check valve if you need to hold a load securely.
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 MI20X20SCM FAQ
This double-acting cylinder uses a 1/8" air 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.
Yes. The Ø20 bore uses the ISO 6432 mounting interface for standard clevis and bracket compatibility. The included -S magnet allows CMSG, DMSG and EMSG switches to detect the piston, while the CM round end cover aids rear mounting.
