Airtac MI16-20 Stainless Steel Mini Cylinder MI20X590U
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X590U is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 590mm 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 MI20X590U
Generating 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles tasks needing a 590 mm reach. Because 590 mm exceeds the 500 mm standard stroke limit for this 20 mm bore, it is produced as a non-standard, made-to-order unit. The 1/8" port and M8x1.25 male rod thread drive a robust 8 mm piston rod. Its stainless barrel and rod resist mild corrosion, giving it an edge over painted alternatives in damp or washdown settings. Riveted construction keeps the body light, while fixed TPU bumper pads absorb end-of-stroke impact.
For practical sizing, plan for about 94 N of real work at 0.5 MPa, which means it can vertically lift roughly 8 kg with a 2:1 safety margin. The U rear cover provides a 90-degree port orientation, aiding tight plumbing layouts. As this SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X590U Is Used
Long-Reach Diversion
Pushes packages across a wide conveyor belt using the full 590 mm extension, relying on the 157 N push force to redirect heavy cartons without stalling.
High-Bay Ejection
Ejects product totes from tall storage racking where a standard 500 mm stroke falls short, taking advantage of the stainless build to resist humid ambient air.
Film Web Threading
Actuates a guiding arm to thread packaging film across a wide machine bed, using the 90-degree U rear cover to keep air lines neatly routed away from the web.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X590U the Right Cylinder?
When sizing this 20 mm bore unit, consider the adjacent options: a 16 mm bore yields 100.5 N of push at 0.5 MPa, while a 25 mm bore provides 245.3 N. This model is double-acting, operating on filtered air between 0.15-1.0 MPa at speeds of 30-800 mm/s. It conforms to the ISO 6432 mounting dimensions, allowing a direct drop into standard mini-cylinder brackets and clevises.
Because the 590 mm stroke is exceptionally long for a mini cylinder, carefully manage side loads to avoid rod bending. Furthermore, a standard cylinder drifts when air is lost or a valve is centred; the TPU bumpers only decelerate the stroke end and do not act as a lock. To suspend a load securely, install an external rod lock or a pilot-operated check valve.
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 MI20X590U FAQ
This 20 mm bore cylinder uses a 1/8" air port. At 0.5 MPa it generates 157 N of push and 131.9 N of pull. At 0.7 MPa, push is 219.8 N and pull is 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG or EMSG switches. You would need the -S variant for sensing. It uses the ISO 6432 mounting interface for standard brackets, and the fixed TPU bumpers decelerate the stroke but do not function as an adjustable air cushion.
