Airtac MI16-20 Stainless Steel Mini Cylinder MI20X225SCA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X225SCA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 225mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X225SCA
Generating 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 225 mm stroke with ease. The Ø20 mm bore uses a 1/8" port and an M8x1.25 male rod thread. Because the piston carries a magnet, you can mount CMSG, DMSG or EMSG switches directly for position sensing. The stainless barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp washdown areas. Riveted construction keeps the body compact, while fixed TPU bumper pads absorb the impact at stroke end.
For practical sizing, plan for about 94 N of real work at 0.5 MPa, which means it lifts roughly 8 kg vertically with a 2:1 safety margin. The rear CA pivot cover allows articulated clevis mounting. The ISO 6432 mounting interface lets you drop this cylinder straight into standard mini-cylinder brackets without redesigning your footprint.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X225SCA Is Used
Package Diverter Arm
Pushes light cardboard cartons on a packaging line using 157 N of thrust, with the CA clevis accommodating slight angular misalignment during the 225 mm swing.
Lab Sample Ejection
Ejects plastic sample trays from a testing station; the stainless-steel rod withstands occasional chemical splashes while the magnet triggers a DMSG sensor.
Tote Pusher
Indexes small plastic totes 225 mm forward onto a roller conveyor, lifting roughly 8 kg of payload with a safe 2:1 vertical margin.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X225SCA the Right Cylinder?
When sizing this 225 mm stroke model, compare it against its neighbours: the smaller Ø16 bore yields 100.5 N of push at 0.5 MPa, while the larger Ø25 bore provides 245.3 N. Choose this Ø20 unit when you need around 157 N of thrust. The CA rear pivot cover is ideal for applications requiring angular alignment. Because this SKU includes the -S magnet, it is fully ready for CMSG, DMSG or EMSG sensors. A plain double-acting cylinder drifts if air pressure drops or the valve is centred; the TPU bumpers only decelerate the stroke end and do not act as a brake. To suspend a load safely, install an external rod lock or a pilot-operated check valve. At 225 mm, avoid heavy side loads that could bend the Ø8 mm rod, and guide the payload mechanically.
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 MI20X225SCA FAQ
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. This Ø20 mm bore features a 1/8" air port and an M8x1.25 male rod thread.
No, a standard double-acting cylinder drifts when air is lost or the valve is centred. The fixed TPU bumper pads only decelerate the piston near the stroke end; they do not function as a locking brake. To maintain a vertical position, you must add an external rod lock or a pilot-operated check valve.
