About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50SUTC
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation with ease. The Ø20 mm bore uses a 1/8" port and an M8x1.25 male rod thread. Its riveted stainless barrel and rod resist mild corrosion, making it superior to painted alternatives in damp environments. The built-in magnet (-S) directly supports CMSG, DMSG and EMSG switches for position sensing.
For practical sizing, plan for roughly 94 N of actual work at 0.5 MPa, which equates to lifting about 8 kg vertically with a 2:1 safety margin. Fixed TPU bumper pads absorb stroke-end impact without offering adjustable cushioning. The included U back cover provides a 90-degree port orientation, while the TC trunnion mounting allows pivoting articulation.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50SUTC Is Used
Package Diverter
Pushes lightweight cardboard cartons on a packaging line using the 157 N push force, relying on the TC trunnion to pivot smoothly during the 50 mm stroke.
Textile Loom Guide
Shifts a yarn guide mechanism in humid textile facilities where the stainless steel barrel prevents rust that would normally seize painted aluminium bodies.
Parts Ejector
Ejects small plastic moulded parts from an assembly fixture, using the 90-degree U rear cover to keep the 1/8" air lines neatly tucked away from the ejection path.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50SUTC the Right Cylinder?
When sizing this 50 mm stroke unit, verify your payload against the 131.9 N pull force at 0.5 MPa. If your application requires less power, the Ø16 bore offers 100.5 N push; for heavier demands, the Ø25 bore steps up to 245.3 N. The ISO 6432 mounting dimensions on this Ø20 bore ensure it drops directly into standard mini-cylinder brackets and clevises.
Because the fixed TPU bumpers only decelerate the stroke end, this cylinder will drift and cannot hold a load if air pressure drops or the valve is centered. To prevent vertical dropping, integrate an external rod lock or a pilot-operated check valve into your pneumatic 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 MI20X50SUTC FAQ
This double-acting cylinder features a 1/8" 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.
Yes to sensors, no to adjustable cushions. The -S suffix means it has a built-in magnet for CMSG, DMSG or EMSG switches. However, it relies on fixed TPU bumper pads for end-of-stroke deceleration; for adjustable air cushioning, you would need the MIC variant.
