Airtac MI16-20 Stainless Steel Mini Cylinder MI20X200U
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X200U 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 MI20X200U
Generating 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 200 mm travel range with a 1/8" air port. The Ø8 mm piston rod features an M8x1.25 male thread, while the riveted barrel and rod shrug off mild corrosion better than painted alternatives in damp production areas. Fixed TPU bumper pads absorb the impact at each stroke end, decelerating the motion without the complexity of an adjustable cushion.
Because it uses the ISO 6432 mounting interface, the unit drops directly into standard mini-cylinder brackets and clevises. For practical sizing, plan for roughly 94 N of real work at 0.5 MPa, which translates to lifting about an 8 kg part vertically with a 2:1 safety margin. The rear U-style cover provides a 90-degree port and pivot orientation for tight machinery layouts.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X200U Is Used
Package Diverters
Pushes light cartons off a main conveyor belt using 157 N of thrust, leveraging the 90-degree U cover to fit alongside the belt frame.
Lab Sample Ejection
Ejects processed sample trays from a testing station, where the stainless build resists chemical splashes and the 200 mm stroke clears the work area.
Bin Lid Actuation
Opens and closes tall storage bin lids, easily handling the 8 kg vertical lift capacity while fitting into compact racking spaces.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X200U the Right Cylinder?
When sizing this 20 mm bore, dropping down to the Ø16 class reduces the push force to 100.5 N at 0.5 MPa, whereas stepping up to the Ø25 bore increases it to 245.3 N. If your process requires position feedback, note that this specific SKU lacks the internal magnet, meaning it cannot host CMSG, DMSG or EMSG sensors; you would need the -S variant for switch mounting. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion blocks.
With a 200 mm stroke, avoid heavy side loads that could bend the extended rod or cause premature seal wear. Furthermore, this standard cylinder will drift if air pressure is lost or the control valve is centred, as the TPU bumpers only soften the end-of-stroke impact and act as neither a brake nor a position lock. To suspend a load safely during an outage, integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
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 MI20X200U FAQ
At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it provides 219.8 N push and 184.7 N pull. The theoretical maximum force is 32 kgf at 1.0 MPa, and the air port size is 1/8".
No, this specific SKU does not include a magnet, so CMSG, DMSG or EMSG switches cannot be used. You must select the -S magnet variant for position sensing. It uses the ISO 6432 mounting interface and fixed TPU bumper pads rather than an adjustable air cushion.
