Airtac MI16-20 Stainless Steel Mini Cylinder MI20X150UTC
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X150UTC is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 150mm 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 MI20X150UTC
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 150 mm stroke with a 1/8" port and an M8x1.25 male rod thread. The stainless barrel and rod resist mild corrosion, giving it a real edge over painted-steel alternatives in damp or washdown environments. Fixed TPU bumper pads decelerate the piston at the stroke ends, keeping the riveted compact body operating smoothly across the 30-800 mm/s speed range.
Because it conforms to the ISO 6432 mounting dimensions, the cylinder drops directly into standard mini-cylinder brackets and clevises. For real-world sizing, plan for a safe working load of about 94 N, which equates to lifting roughly 8 kg vertically with a 2:1 safety margin. Note that this specific SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG position switches without upgrading to the -S variant.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X150UTC Is Used
Package Diverter Gate
Actuates a routing flap on a packaging line, using the 157 N push force to redirect cardboard cartons at high speed without overstressing the mechanism.
Textile Loom Tensioner
Employs the 150 mm stroke and TC trunnion to pivot a yarn tensioning arm, maintaining consistent material feed in a humid manufacturing environment.
Pallet Labelling Arm
Extends to press an adhesive label onto incoming pallets, relying on the stainless construction to withstand occasional washdowns during facility cleaning.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X150UTC the Right Cylinder?
When sizing this 20 mm bore, the smaller 16 mm option yields 100.5 N of push at 0.5 MPa, while the larger 25 mm bore provides 245.3 N, letting you step up if the 150 mm stroke needs to shift heavier tooling. This configuration includes a U-type 90-degree rear cover and a TC trunnion mount, which accommodates pivoting loads along the stroke axis. If your mechanism relies on maintaining vertical position during an air loss or valve centre state, remember that the piston will drift; the bumper pads only soften the end of travel, so you must fit an external rod lock or pilot-operated check valve to secure the load.
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 MI20X150UTC 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 force of 32 kgf at 1.0 MPa.
This specific SKU does not have a magnet and cannot support CMSG, DMSG or EMSG switches; you would need the -S variant for sensing. It uses standard ISO 6432 mounting dimensions, includes a U 90-degree back cover, and is paired here with a TC trunnion bracket for pivoting applications.
