Airtac MI16-20 Stainless Steel Mini Cylinder MI20X700SU
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X700SU 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 MI20X700SU
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles extended reach tasks with a 700 mm stroke. Because 700 mm exceeds the 500 mm standard maximum for this bore, it is manufactured as a made-to-order unit. The stainless barrel and rod naturally resist mild corrosion, giving it a distinct advantage over painted alternatives in damp or washdown settings. It features a 1/8" port and an M8x1.25 male rod thread.
The riveted construction keeps the body compact, while fixed TPU bumper pads absorb impact at the stroke extremes. Equipped with a built-in magnet (-S), it supports CMSG, DMSG and EMSG sensors for position detection. Plan for a safe working load of roughly 94 N, which means you can vertically lift about 8 kg with a 2:1 safety margin. The U-type back cover provides a 90-degree port orientation for tight spatial constraints.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X700SU Is Used
Long-Reach Diversion
Pushes packages across a sorting line using the full 700 mm extension, relying on the 157 N force to deflect heavy cartons without stalling.
Vertical Material Lift
Raises lightweight tote bins in a storage rack, safely lifting an 8 kg payload vertically thanks to the calculated 2:1 safety margin.
Sample Ejection
Ejects processed laboratory samples from a damp testing chamber, where the stainless steel rod prevents mild corrosion from repeated washdowns.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X700SU the Right Cylinder?
When sizing this actuator, consider the neighbouring bores: the smaller Ø16 generates 100.5 N of push at 0.5 MPa, while the larger Ø25 provides 245.3 N. This Ø20 model fits neatly in the middle, but its 700 mm stroke demands careful alignment to prevent rod bending and premature seal wear under side loading. The ISO 6432 mounting interface allows it to drop directly into standard mini-cylinder brackets and clevises. You can utilise LB foot, FA flange, SDB pivot, or TC trunnion hardware.
Remember that a standard actuator will drift if air pressure drops or the valve is centred; the bumper pads only decelerate the end of travel and do not function as a brake. To suspend a load securely during an air loss event, install an external rod lock or a pilot-operated check valve in the system.
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 MI20X700SU FAQ
This 20 mm bore cylinder uses a 1/8" 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, the piston will drift if air pressure is lost or the valve is centred. The fixed TPU bumper pads only decelerate the stroke end and do not act as a lock. You must add an external rod lock or pilot check valve to hold a suspended load.
