Airtac MI16-20 Stainless Steel Mini Cylinder MI16X20SUTC
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X20SUTC is a genuine double acting round-body mini air cylinder with a Ø16mm 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 MI16X20SUTC
Generating 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles compact actuation with a 20 mm stroke. The riveted round-body construction pairs a corrosion-resistant barrel and rod with fixed TPU bumper pads that soften stroke-end impacts without offering adjustable cushioning. Because the bore is Ø16, it uses the ISO 6432 mounting interface, dropping directly into standard mini-cylinder brackets and clevises for straightforward design integration.
The built-in piston magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing, while the U back cover provides a 90-degree port orientation. In practical terms, you should plan for a safe working load of about 60 N rather than the absolute maximum rating. For vertical lifts, this translates to raising a part weighing roughly 5.1 kg with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X20SUTC Is Used
Component Ejection
Pushes small stamped metal parts out of a die set using the 20 mm stroke, where the 100.5 N output and fixed TPU bumpers absorb the end-of-travel shock.
Package Diverting
Actuates a short routing gate on a packaging line, utilising the TC trunnion mount to pivot the mechanism and the -S magnet to confirm gate position.
Product Sorting
Defects lightweight plastic bottles on a quality control conveyor, taking advantage of the stainless-steel build to resist washdown chemicals in damp facilities.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X20SUTC the Right Cylinder?
When sizing this 16 mm bore, the smaller Ø12 option yields 56.5 N of push at 0.5 MPa, whereas stepping up to the Ø20 bore provides 157.0 N. The included TC trunnion mount works alongside the U back cover to handle pivoting loads, but remember that a standard cylinder drifts if air pressure drops or the valve is centred. To prevent movement on a suspended load, install an external rod lock or a pilot-operated check valve rather than relying on the bumpers.
With a short 20 mm stroke, side-load stress on the Ø6 mm rod is minimal, making it ideal for tight clamping or ejecting spaces. The 1/8" port matches the bore size for adequate airflow across the 30-800 mm/s speed range.
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 MI16X20SUTC FAQ
This 16 mm bore cylinder has a 1/8" port. At 0.5 MPa it provides 100.5 N push and 86.4 N pull. At 0.7 MPa it delivers 140.7 N push and 120.9 N pull. The theoretical maximum force is 20.5 kgf at 1.0 MPa.
No, a plain cylinder drifts if air is lost or the valve is centred; the fixed TPU bumpers only decelerate the stroke end and do not act as a brake. For holding a load, use an external rod lock or pilot check valve. The built-in magnet (-S) allows fitting CMSG, DMSG or EMSG switches for position detection.
