Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50CA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50CA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 50mm 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 MI20X50CA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles robust actuation tasks. The riveted Ø20 mm body uses a 1/8" 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. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches.
For practical sizing, plan for about 94 N of actual work at 0.5 MPa, which safely lifts an 8 kg load vertically with a 2:1 margin. The built-in fixed TPU bumper pads decelerate the piston at stroke end to absorb impact. Conforming to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50CA 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 medium-weight cartons reliably.
Textile Loom Tensioner
Maintains thread tension in a humid manufacturing environment where the stainless steel barrel prevents mild corrosion that would stall standard cylinders.
Parts Ejector Mechanism
Pushes stamped metal components out of a press area, using the fixed TPU bumper pads to decelerate the 50 mm stroke and prevent end-of-travel impact damage.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50CA the Right Cylinder?
When sizing this bore, stepping down to the Ø16 model drops the 0.5 MPa push force to 100.5 N, while moving up to the Ø25 raises it to 245.3 N. This specific configuration includes a CA rear pivot clevis, ideal for articulating loads. If your application requires position holding, note that a plain cylinder drifts when air is lost or the valve is centred; the bumpers only soften the stroke end, so you must add an external rod lock or pilot check valve to hold a load securely.
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 MI20X50CA FAQ
This Ø20 mm bore cylinder features a 1/8" 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 of 32 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensor tracking. It uses the ISO 6432 mounting interface and includes a CA pivot clevis for articulating installations.
