Airtac MI16-20 Stainless Steel Mini Cylinder MI20X450U
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X450U is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 450mm 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 MI20X450U
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 450 mm stroke with ease. The Ø20 mm bore uses a 1/8 inch port and an M8x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. The U suffix denotes a 90-degree rear cover, optimizing port and mounting orientation for tight spaces.
Because the fixed TPU bumper pads only decelerate the stroke end rather than acting as a lock, plan for a safe working load of about 94 N. Alternatively, you can expect to lift roughly 8 kg vertically with a 2:1 safety margin. This SKU lacks the -S magnet, so it cannot accept CMSG, DMSG or EMSG position switches without changing to a magnetized variant.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X450U Is Used
Package Diverter Arm
Pushes light cardboard cartons on a packaging line using 157 N of force, with the 450 mm stroke reaching cleanly across a narrow belt.
Textile Loom Tensioner
Adjusts yarn guides in humid textile mills where the stainless steel barrel prevents mild corrosion from ambient moisture.
Bin Lid Actuator
Lifts a hinged lid on a sorting bin, safely handling an 8 kg cover vertically thanks to the 2:1 safety margin on the 0.5 MPa output.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X450U the Right Cylinder?
When sizing this 450 mm stroke model, verify your side-load limits to prevent rod bending over the long extension. If you need less force, the Ø16 bore provides 100.5 N push at 0.5 MPa; for heavier duty, the Ø25 bore offers 245.3 N. The ISO 6432 mounting interface on this Ø20 bore drops directly into standard mini-cylinder brackets and clevises, maximizing design flexibility.
Note that a plain double-acting cylinder drifts when air is lost or the valve is centered, as the bumpers only soften impact and never hold the load. For vertical applications requiring position holding, specify an external rod lock or a pilot-operated check valve. Furthermore, because this specific configuration lacks a magnet, it cannot support magnetic sensing.
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 MI20X450U FAQ
This double-acting cylinder uses a 1/8 inch port and generates 157 N push / 131.9 N pull at 0.5 MPa, and 219.8 N push / 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa.
The Ø20 bore uses the ISO 6432 mounting interface, so it fits standard mini-cylinder clevises and brackets. However, because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG switches; you must select a magnetized variant for position sensing.
