About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X30SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles compact automation with ease. The Ø20 mm bore operates on a 1/8" port and features a CA pivot clevis back cover for straightforward articulated mounting. Its riveted round-body construction uses a stainless barrel and rod, resisting mild corrosion in damp or washdown environments better than painted alternatives.
The built-in magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing, while fixed TPU bumper pads absorb end-of-stroke impacts. For practical sizing, plan for roughly 94 N of actual work at 0.5 MPa, which means it can safely lift an 8 kg load vertically with a 2:1 safety margin. The 30 mm stroke operates at speeds from 30 to 800 mm/s.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X30SCA Is Used
Package Diverter Arm
Uses the 157 N push force and CA clevis to swing a lightweight routing gate on a packaging line, safely handling products up to 8 kg.
Small Parts Ejector
Rapidly ejects machined components from a fixture using the 30 mm stroke, relying on fixed TPU bumpers to soften the impact at full extension.
Bin Lid Actuation
Opens and closes damp-access hopper lids where the stainless steel barrel and rod prevent mild corrosion from humidity or occasional washdowns.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X30SCA the Right Cylinder?
Choosing this Ø20 mm bore means sizing against the Ø16 mm option, which offers 100.5 N of push at 0.5 MPa, and the larger Ø25 mm bore, which pushes 245.3 N. If your payload drops when air is removed or the valve centers, remember this cylinder will drift; the TPU bumpers only decelerate the stroke end and act as neither a lock nor a brake. To hold a suspended load securely, integrate an external rod lock or a pilot-operated check valve.
The integrated CA rear clevis suits pivot-mount installations, and the -S magnet enables electronic or reed sensing. Because the 30 mm stroke is quite short, side-load risks are minimal, but ensure the front and rear pivots align properly to prevent rod binding. The ISO 6432 mounting dimensions allow this unit to drop directly into standard mini-cylinder brackets.
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 MI20X30SCA FAQ
This double-acting cylinder uses a 1/8" port. At 0.5 MPa it pushes 157 N and pulls 131.9 N. At 0.7 MPa it pushes 219.8 N and pulls 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa.
Yes, the -S designation means it has a built-in piston magnet compatible with CMSG, DMSG and EMSG switches. The CA back cover provides a pivot clevis pin mount for articulated movement, conforming to ISO 6432 dimensions for standard brackets.
