Airtac MI16-20 Stainless Steel Mini Cylinder MI20X580U
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X580U is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 580mm 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 MI20X580U
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles demanding automation tasks. The 580 mm stroke exceeds the 500 mm standard maximum for this bore, making it a non-standard, made-to-order unit. Its riveted stainless barrel and rod shrug off mild corrosion, outlasting painted alternatives in damp or washdown settings. A 1/8" port feeds the 8 mm rod for rapid cycling.
Because the piston must travel 580 mm, plan for about 94 N of actual work at 0.5 MPa to maintain smooth motion rather than maxing out the rating. This equates to lifting an 8 kg payload vertically with a safe 2:1 margin. The U-style back cover mounts at 90 degrees for compact footprint integration. Fixed TPU bumper pads absorb the end-of-stroke impact, though this SKU lacks a magnet and cannot host CMSG, DMSG, or EMSG sensors.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X580U Is Used
Long-Reach Diverting
Pushes parcels across a wide sorting belt using the extended 580 mm travel, relying on the 157 N thrust to redirect heavy cartons without stalling.
Vertical Parts Elevator
Lifts approximately 8 kg of stacked trays between conveyor tiers, utilizing the 90-degree U cover for tight frame mounting and the stainless rod for humid environments.
Film Roll Feed
Actuates a packaging film tensioning arm over a long distance, where the fixed TPU bumpers quietly absorb the rapid stroke-end impacts during continuous cycling.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X580U the Right Cylinder?
When sizing this 20 mm bore, dropping down to the Ø16 variant yields 100.5 N of push at 0.5 MPa, while stepping up to the Ø25 provides 245.3 N. This 580 mm stroke is a special order; at that length, side-load forces risk bending the 8 mm rod, so precise guide alignment is critical. The U-type rear cover provides a 90-degree mounting plane that helps manage spatial constraints on long assemblies.
Air pressure loss will cause the piston to drift, as the TPU bumpers only decelerate the stroke end and do not function as a locking brake. To suspend a vertical load safely, install an external rod lock or a pilot-operated check valve. Without the -S suffix, this unit cannot accept position switches; if sensing is required, select the magnet-equipped version and pair it with CMSG, DMSG, or EMSG switches.
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 MI20X580U FAQ
This 20 mm bore cylinder uses a 1/8" port and an 8 mm rod. 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. The 580 mm stroke is a non-standard, made-to-order length.
Yes, the 20 mm bore uses the ISO 6432 mounting interface, so it drops into standard mini-cylinder brackets and clevises. However, because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG sensors; you must select the -S variant for position detection.
