Airtac MI16-20 Stainless Steel Mini Cylinder MI20X700U
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X700U is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 700mm 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 MI20X700U
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles demanding linear motion tasks. The 700 mm stroke is a non-standard, made-to-order length that exceeds the usual 500 mm maximum for this Ø20 bore, making it ideal for applications requiring extended travel. It features a 1/8" port and an M8x1.25 male rod thread.
The stainless barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches. Plan for a safe working load of roughly 94 N (about 60 percent of the 0.5 MPa rating), which translates to lifting an 8 kg part vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X700U Is Used
Extended-Reach Diverters
Uses the full 700 mm stroke to push packages across wide transfer belts, leveraging the 157 N push force to redirect heavy cartons smoothly.
Textile Beam Handling
Loads and unloads long material beams in textile machinery, where the stainless build resists humid dye-house environments and the U cover eases mounting.
High-Bay Ejection
Ejects totes from vertical storage lifts, taking advantage of the extended travel to clear the 8 kg safe lifting capacity safely into downstream chutes.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X700U the Right Cylinder?
When sizing this actuator, the neighbouring Ø16 bore offers 100.5 N of push at 0.5 MPa, while stepping up to the Ø25 yields 245.3 N, helping you bracket your actual force needs. The U-style back cover provides a 90-degree port and mounting orientation for tight spatial constraints. Because this is a 700 mm stroke on a Ø20 rod, be mindful of side-loading and rod-bending moments over that extended travel. Fixed TPU bumper pads decelerate the piston at the stroke ends but do not act as an adjustable air cushion. Finally, a plain double-acting cylinder drifts when air is lost or the valve is centered; to hold a load securely, install an external rod lock or a pilot-operated check valve rather than relying on the bumpers.
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 MI20X700U FAQ
This Ø20 bore cylinder features a 1/8" port and an M8x1.25 male rod thread. 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 force of 32 kgf at 1.0 MPa.
No, this SKU lacks the internal magnet required for CMSG, DMSG, or EMSG switches; you would need the -S variant for sensing. Additionally, the fixed TPU bumpers only decelerate the stroke end and do not lock the piston, so the rod will drift on air loss unless you add an external rod lock or pilot check valve.
