Airtac MI16-20 Stainless Steel Mini Cylinder MI20X70SCA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X70SCA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 70mm 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 MI20X70SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles robust actuation with a 70 mm stroke. The riveted construction pairs a corrosion-resistant barrel and rod with fixed TPU bumper pads that absorb end-of-stroke impacts without the need for adjustable cushioning. Its CA rear pivot cover simplifies clevis mounting, while the 1/8" port ensures efficient air flow for rapid 30-800 mm/s cycling.
Because the piston pushes with 157 N at 0.5 MPa, you can plan for roughly 94 N of actual work to maintain a safe margin. Vertically, that same pressure translates to lifting about 8 kg when you halve the raw force for a 2:1 safety factor. The built-in -S magnet enables CMSG, DMSG or EMSG position sensing, and its ISO 6432 mounting dimensions mean it drops straight into standard mini-cylinder brackets.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X70SCA Is Used
Package Diverting Gate
Actuates a routing flap on a 500 mm/s packaging line, using the 70 mm stroke to push parcels cleanly into secondary sorting lanes.
Textile Loom Tensioner
Adjusts yarn guide arms in damp textile environments, where the stainless-steel barrel resists humidity and mild washdown better than painted alternatives.
Pallet Labelling Arm
Extends a label applicator head precisely 70 mm toward pallets, relying on the CA pivot to accommodate slight angular misalignment during contact.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X70SCA the Right Cylinder?
If you need less push, the Ø16 bore offers 100.5 N at 0.5 MPa, whereas stepping up to the Ø25 provides 245.3 N for heavier loads. Remember that this standard MI relies on its bumper pads only to decelerate the stroke end; it will drift and cannot hold a load if air pressure drops or the valve is centred. For suspended or vertical loads, add an external rod lock or a pilot-operated check valve. The CA back cover on this specific unit is designed for pivot mounting, and the integrated magnet supports reed or electronic sensors without modification.
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 MI20X70SCA FAQ
At 0.5 MPa it pushes with 157 N and pulls with 131.9 N. At 0.7 MPa the push is 219.8 N and pull is 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa, and the air port size is 1/8".
Yes, the -S suffix indicates a built-in piston magnet compatible with CMSG, DMSG and EMSG switches. However, it does not hold position on air loss; the TPU bumpers only decelerate the stroke end, so use a pilot check valve or external rod lock for suspended loads.
