About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X115SU
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 115 mm stroke with a robust Ø8 mm piston rod. The riveted barrel and rod resist mild corrosion, making it highly suitable for damp production areas where painted steel quickly degrades. Its built-in piston magnet directly supports CMSG, DMSG, and EMSG switches for precise end-of-stroke detection.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X115SU Is Used
Lab Sample Ejection
Ejects processed sample trays from a wet chemical analyzer, leveraging the stainless-steel construction to withstand humid, mildly corrosive environments.
Tote Pusher Mechanism
Pushes empty totes into position on a gravity conveyor, utilizing the 115 mm stroke and U-style 90-degree rear pivot for a compact machine footprint.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X115SU the Right Cylinder?
When sizing this 20 mm bore unit, consider scaling down to the Ø16 class if your application only requires 100 N of push at 0.5 MPa, or stepping up to the Ø25 class for a substantial 245 N when heavier payloads are involved. The U-style rear cover provides a 90-degree mounting orientation, easily pairing with standard clevis brackets.
Note that the fixed TPU bumper pads only decelerate the piston near the stroke end; they do not function as a lock. If the mechanism must hold a vertical load during air loss or valve centering, the piston will drift, requiring an external rod lock or pilot-operated check valve. Additionally, the 115 mm stroke demands careful alignment to prevent rod bending under side loads.
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 MI20X115SU FAQ
This 20 mm bore cylinder features a 1/8" air 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.
Yes, the -S suffix indicates a built-in piston magnet compatible with CMSG, DMSG, and EMSG switches. The U rear cover provides a 90-degree pivot mounting interface, and the cylinder body conforms to ISO 6432 mounting dimensions for standard mini-cylinder brackets.
