Airtac MI16-20 Stainless Steel Mini Cylinder MI20X140CA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X140CA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 140mm 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 MI20X140CA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 140 mm stroke with a CA pivot clevis. The riveted stainless barrel and Ø8 mm rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Because it follows ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets.
At 0.5 MPa you get 131.9 N of pull force, and the 1/8" port feeds air efficiently across the 30-800 mm/s speed range. Plan for roughly 94 N of actual work at that pressure, which means it lifts about 8 kg vertically with a safe 2:1 margin. Fixed TPU bumper pads absorb the impact at stroke end, and since this specific SKU lacks the -S magnet, it cannot host CMSG, DMSG or EMSG sensors.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X140CA Is Used
Package Diverter Gate
Pivots a sorting flap on a packaging line using the CA clevis, relying on the 157 N push force to redirect small cartons at high cycling speeds.
Film Roll Tensioner
Maintains proper web tension on a wrapping machine, where the stainless steel construction resists humidity and the 140 mm stroke accommodates varying roll diameters.
Component Ejector
Pushes machined parts out of a fixture, lifting roughly 8 kg of dead weight vertically with a safe 2:1 margin before retracting at 0.5 MPa.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X140CA the Right Cylinder?
When sizing this 20 mm bore, stepping down to the MI16 yields 100.5 N of push, while stepping up to the MI25 provides 245.3 N at 0.5 MPa. The 140 mm stroke is well within the 500 mm maximum, but at this extension you must watch out for side-loading and rod-bending forces to prevent premature seal wear. The built-in CA rear clevis is ideal for pivoting loads.
Remember that a standard double-acting cylinder drifts if air pressure drops or the valve is centered, as the TPU bumpers only soften the end-of-stroke impact rather than locking the rod. To suspend a load safely during an air loss event, fit an external rod lock or a pilot-operated check valve. If your application requires position sensing, select the -S magnet version to enable switch mounting.
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 MI20X140CA FAQ
This 20 mm bore cylinder features a 1/8" air 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 force of 32 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet, so it cannot host CMSG, DMSG or EMSG switches. You would need to select the -S variant for sensing capabilities. It uses fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable air cushion.
