About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X350SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 350 mm stroke with ease. The Ø20 mm bore uses a 1/8 inch port and an M8x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. The built-in piston magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing.
Because the 157 N rating is theoretical, plan for a safe working load of about 94 N at 0.5 MPa. This translates to lifting roughly 8 kg vertically with a 2:1 safety margin. The riveted body keeps the unit compact, while fixed TPU bumper pads absorb the impact at stroke end. The CA rear cover provides an integrated pivot clevis for straightforward angular mounting.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X350SCA Is Used
Package Diverter
Pushes light cardboard cartons on a packaging line using 157 N of thrust, with the CA clevis allowing the arm to pivot smoothly during the 350 mm travel.
Textile Loom Tensioner
Maintains yarn tension in a humid textile facility, leveraging the stainless steel rod and barrel to resist mild corrosion while cycling rapidly.
Parts Ejector
Sweeps finished plastic mouldings from a press bed over a 350 mm distance, relying on the fixed TPU pads to soften the end-of-stroke impact.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X350SCA the Right Cylinder?
If 94 N of safe working load is insufficient, step up to the Ø25 bore (245 N push at 0.5 MPa); if you are oversizing, drop down to the Ø16 bore (100 N push at 0.5 MPa). At 350 mm, this long stroke requires careful alignment to prevent rod bending and premature seal wear from side loads. The CA pivot clevis helps accommodate minor misalignment.
Remember that a standard cylinder drifts when air is lost or the valve is centred, as the TPU pads only decelerate the stroke end rather than locking the piston. To suspend a load safely, install an external rod lock or a pilot-operated check valve. This SKU includes the -S magnet for sensors, and its ISO 6432 mounting dimensions drop directly into standard mini-cylinder brackets.
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 MI20X350SCA FAQ
At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it provides 219.8 N push and 184.7 N pull. The theoretical maximum force is 32 kgf at 1.0 MPa. The air port is 1/8 inch.
No, the piston drifts if air is lost because the TPU pads only decelerate the stroke end rather than acting as a brake; use a pilot check valve for holding. The CA designation means the rear cover features a pivot clevis for angular mounting.
