About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X270SU
Generating 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 270 mm stroke with ease. The Ø20 mm bore uses a 1/8 inch port and an M8x1.25 male rod thread. Its riveted stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. The built-in magnet allows direct mounting of CMSG, DMSG, or EMSG sensors.
With a 157 N push rating at 0.5 MPa, you can plan for roughly 94 N of actual work output. This translates to lifting about 8 kg vertically with a safe 2:1 margin. The U-type back cover provides a 90-degree port orientation for tight routing. Fixed TPU bumper pads absorb the impact at stroke extremes, decelerating the piston without the complexity of adjustable cushioning.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X270SU Is Used
Diverter Gate Actuation
Pushes routing flaps on packaging lines with 157 N at 0.5 MPa, using the 270 mm stroke to clear wide product lanes.
Lab Sample Ejection
Ejects processed sample trays from test equipment where the stainless body tolerates frequent chemical wipe-downs.
Light Press Operation
Applies downward clamping pressure on light assemblies, safely lifting parts up to 8 kg during vertical movements.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X270SU the Right Cylinder?
When sizing this unit, the smaller Ø16 bore provides 100.5 N of push at 0.5 MPa, while the larger Ø25 bore steps up to 245.3 N, letting you fine-tune force to the load. The 270 mm stroke is well within the 500 mm maximum standard stroke for this bore, making it a readily available size. Because the piston drifts when air is removed or a valve is centered, add an external rod lock or pilot check valve if your application must hold a vertical load in place. The integrated magnet means the unit is fully ready for position sensing.
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 MI20X270SU FAQ
This Ø20 mm bore cylinder features a 1/8 inch port and an M8x1.25 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, it relies on fixed TPU bumper pads to decelerate the piston at the stroke ends. For high-speed variable cushioning, you would need the MIC variant. This model also uses the ISO 6432 mounting interface for easy bracket matching.
