Airtac MI16-20 Stainless Steel Mini Cylinder MI20X20U
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X20U is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 20mm 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 MI20X20U
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles brief 20 mm strokes with efficiency. The riveted barrel and rod shrug off mild corrosion, outlasting painted alternatives in damp or washdown environments. Its compact footprint includes a U-type back cover that presents the air port at a 90-degree angle for tight machinery layouts.
With a 1.0 MPa maximum pressure and a 1/8" port, the unit relies on fixed TPU bumper pads to decelerate the stroke end rather than adjustable cushions. Plan for a real working load of roughly 94 N, which lets you lift about 8 kg vertically with a 2:1 safety margin. Because this specific SKU lacks the -S magnet, it cannot host CMSG, DMSG, or EMSG position switches.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X20U Is Used
Package Deflector
Snaps out a 20 mm stroke to push light cardboard cartons off a packaging line, utilizing the 157 N push force to overcome guide friction.
Pneumatic Valve Actuation
Cycles a small process valve in humid plant environments where the stainless steel barrel prevents corrosion from ambient moisture.
Parts Ejector
Kicks completed plastic parts out of a molding fixture, lifting roughly 8 kg of tooling weight vertically with a safe 2:1 margin.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X20U the Right Cylinder?
If your application requires less thrust, the Ø16 bore provides 100.5 N at 0.5 MPa, whereas stepping up to the Ø25 bore yields 245.3 N for heavier resistance. This Ø20 model strikes a balance with a 20 mm stroke that minimizes rod bending under side loads. The U-type rear cover simplifies plumbing in confined spaces by turning the port 90 degrees.
Remember that venting the air supply causes the piston to drift, as the TPU bumpers only soften end impacts and never act as a brake. To suspend a load securely during an air loss event, integrate an external rod lock or a pilot-operated check valve into your 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 MI20X20U FAQ
This 20 mm 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 of 32 kgf at 1.0 MPa.
No, this specific SKU lacks the internal magnet required for switches. You must select the -S variant to use CMSG, DMSG, or EMSG sensors. It uses the ISO 6432 mounting interface for standard brackets and features fixed TPU bumpers, not adjustable air cushions.
