About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X230SU
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 230 mm stroke with ease. The Ø20 mm bore operates on a 1/8" port, while the riveted barrel and rod resist mild corrosion in damp or washdown environments better than painted alternatives. A built-in magnet (-S) enables direct mounting of CMSG, DMSG, or EMSG switches for position sensing.
The fixed TPU bumper pads decelerate the piston at stroke ends, and the U-type back cover provides a 90-degree port orientation for tight machinery layouts. Plan for a safe working load of roughly 94 N, which translates to lifting about 8 kg vertically with a 2:1 safety margin. Because it adheres to ISO 6432 mounting dimensions, this unit drops seamlessly into standard mini-cylinder brackets and clevises.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X230SU Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using the 157 N push force to redirect cartons at high speed.
Vertical Parts Lift
Raises lightweight 8 kg fixtures between machine tiers, relying on the 230 mm stroke to bridge the gap.
Damp Environment Ejector
Pushes machined parts out of a coolant wash station, leveraging the stainless steel barrel for moisture resistance.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X230SU the Right Cylinder?
When sizing this 230 mm stroke unit, verify the 8 mm rod can handle the extension without excessive side loading. If less force is needed, the Ø16 bore provides 100.5 N push at 0.5 MPa; for heavier cycles, the Ø25 bore offers 245.3 N. The 1/8" port and M8x1.25 male rod thread are fixed by the 20 mm bore.
Note that a standard double-acting cylinder drifts when air is lost or the valve is centered, as the TPU bumpers only soften end impacts rather than locking the load. To suspend a vertical weight safely, 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 MI20X230SU FAQ
This Ø20 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 of 32 kgf at 1.0 MPa.
No, the piston will drift if air pressure is lost or the valve is centered; an external rod lock or pilot check valve is required to hold a load. The unit uses fixed TPU bumper pads to decelerate at stroke ends, not an adjustable air cushion, and its built-in magnet supports CMSG, DMSG, or EMSG sensors.
