About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X95SU
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 95 mm stroke with a durable riveted construction. The Ø20 mm bore operates on a 1/8" port and features a U-type 90-degree rear cover for compact pivot or side-mounting orientations. Its stainless barrel and piston rod naturally resist mild corrosion, giving it a distinct edge over painted alternatives in damp or washdown environments.
The built-in piston magnet (-S) directly supports CMSG, DMSG, and EMSG electronic or reed switches for position sensing. Fixed TPU bumper pads absorb end-of-stroke impact without adding bulk. For practical sizing, plan for roughly 94 N of actual work at 0.5 MPa, which means it can safely lift about 8 kg vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X95SU Is Used
Package Diverter
Pushes light cardboard cartons on a packaging line using 157 N of thrust, with the U cover allowing a compact 90-degree mount alongside the belt.
Lab Sample Ejection
Ejects processed fluid samples from a testing carousel, where the stainless rod resists mild chemical corrosion from occasional splashes.
Parts Sorting Gate
Actuates a routing gate for small plastic components, using the integrated magnet and a DMSG switch to confirm the 95 mm stroke position.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X95SU the Right Cylinder?
When sizing this actuator, the Ø16 mm bore provides a lighter 100.5 N push at 0.5 MPa, while stepping up to the Ø25 mm bore yields 245.3 N if your payload exceeds the 8 kg vertical lift threshold. Because this standard configuration lacks an external rod lock, the piston will drift if air pressure drops or the valve is centred; integrate a pilot-operated check valve to suspend a load safely. The 95 mm stroke is well within the 500 mm maximum, but always ensure front and rear mounts are aligned to prevent rod bending under lateral stress. Thanks to the ISO 6432 mounting interface, it drops directly into standard mini-cylinder brackets and clevises.
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 MI20X95SU FAQ
This double-acting cylinder uses 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.
No, the piston will drift downward if air pressure is lost or the valve is centred. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. You must add an external rod lock or pilot check valve to hold a load securely.
