Airtac MI16-20 Stainless Steel Mini Cylinder MI20X200CMH
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X200CMH is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 200mm 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 MI20X200CMH
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 200 mm stroke with ease. The riveted barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Because it lacks the -S suffix, this specific SKU cannot host CMSG, DMSG or EMSG magnetic sensors. The -H designation equips the unit with high-temperature Viton seals, extending its reliability in heated environments.
In practical terms, you should plan for a safe working load of about 94 N, which is roughly 60 percent of the 0.5 MPa push rating. Alternatively, it can vertically lift an 8 kg part with a 2:1 safety margin. The 1/8" port feeds air to both chambers, while the CM round back cover keeps the rear profile smooth. Fixed TPU bumper pads absorb the impact at stroke extremes, decelerating the motion without offering adjustable cushioning.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X200CMH Is Used
Hot End Diverter Gate
Actuates a routing flap on a conveyor transporting freshly moulded components, utilising the Viton -H seals to withstand ambient radiated heat.
Film Roll Tensioner
Maintains precise 94 N pressure on a packaging web roller, leveraging the 200 mm stroke to accommodate varying material roll diameters.
Lab Washdown Ejector
Pushes treated sample trays out of a sterile chamber, where the stainless-steel barrel resists moisture and harsh cleaning chemicals.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X200CMH the Right Cylinder?
When sizing this 20 mm bore, stepping down to a 16 mm bore drops the 0.5 MPa push force to 100.5 N, whereas moving up to a 25 mm bore increases it to 245.3 N. The 200 mm stroke is well within the 500 mm maximum for this bore, but at extended lengths you must watch out for rod bending and side-load stress on the Ø8 mm piston rod. You can mount the body using standard LB foot, FA flange, SDB pivot or TC trunnion hardware. The ISO 6432 mounting interface on this Ø20 bore ensures it drops directly into standard mini-cylinder brackets and clevises.
Remember that a standard double-acting cylinder drifts if air pressure drops or the valve is centred, as the TPU bumpers only soften the end-of-stroke impact rather than locking the rod. To suspend a load safely, fit an external rod lock or a pilot-operated check valve. If your application requires position feedback, select the -S magnet version instead, as this unit cannot carry a switch.
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 MI20X200CMH FAQ
This 20 mm bore 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.
No, because this model lacks the -S suffix, it has no internal magnet and cannot accept CMSG, DMSG or EMSG switches. You would need the -S variant to enable sensing.
