Airtac MI16-20 Stainless Steel Mini Cylinder MI20X30R
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X30R is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 30mm 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 MI20X30R
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles short 30 mm strokes with precision. The riveted barrel and rod resist mild corrosion, making it superior to painted alternatives in damp production areas. It uses a 1/8" port and an M8x1.25 male rod thread.
Because the rated output is a theoretical ceiling, plan for a safe working load of roughly 94 N to account for friction and real-world dynamics. If lifting vertically, that translates to hoisting about 8 kg safely with a 2:1 margin. The fixed TPU bumper pads absorb stroke-end impact, and the rear R cover provides an axial-in port orientation for tight manifold routing.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X30R Is Used
Short-Stroke Clamping
Secures aluminum extrusions in a CNC machining fixture using the 157 N push force over a rapid 30 mm travel distance.
Carton Flap Folding
Folds corrugated cardboard flaps on a packaging line where the stainless build withstands occasional washdowns and damp environments.
Diverter Gate Actuation
Pivots a lightweight routing gate on a conveyor system, utilizing the rear R axial port to keep pneumatic hoses neatly tucked away.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X30R the Right Cylinder?
When sizing this 20 mm bore, stepping down to a 16 mm bore yields 100.5 N of push force at 0.5 MPa, while moving up to a 25 mm bore provides 245.3 N. This 30 mm stroke keeps the rod compact and minimizes side-load bending moments. The standard ISO 6432 mounting interface means it drops directly into common mini-cylinder brackets and clevises.
Note that this specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG or EMSG position switches. Furthermore, the fixed bumpers only decelerate the stroke end; they do not act as a brake. If your process requires the piston to stay put upon air loss or valve centering, you must add an external rod lock or a pilot-operated check valve to prevent drift.
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 MI20X30R 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.
No, this specific SKU does not include the -S magnet required for CMSG, DMSG or EMSG switches. You would need the -S variant for position sensing. It uses fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable air cushion.
