Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50SCA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50SCA 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 MI20X50SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation with reliability. The riveted barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. Because the Ø20 bore falls within the Ø8-Ø25 range, it uses the ISO 6432 mounting interface, dropping directly into standard mini-cylinder brackets.
The integrated piston magnet supports CMSG, DMSG and EMSG switches for position sensing, while the built-in CA rear clevis simplifies pivot mounting. Fixed TPU bumper pads absorb stroke-end impact. For actual moving tasks, plan for around 94 N of real work at 0.5 MPa, which equates to lifting about 8 kg vertically with a safe 2:1 margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50SCA Is Used
Package Diverter Gate
Swings a lightweight sorting flap on a packaging line using the CA pivot mount, applying 157 N to push parcels smoothly onto secondary chutes.
Textile Loom Tensioner
Pivots a yarn guide arm in humid textile facilities, leveraging the stainless construction to resist moisture while maintaining consistent thread tension.
Bin Lid Actuation
Lifts an 8 kg access hatch on an automated storage hopper, relying on the 50 mm stroke and the rear clevis to swing the cover open safely.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50SCA the Right Cylinder?
Sizing this 50 mm stroke actuator requires checking both neighbours: dropping to the Ø16 bore lowers the 0.5 MPa push to 100.5 N, whereas stepping up to the Ø25 bore raises it to 245.3 N. If your process loses air or the valve centres, this cylinder will drift and cannot hold a load—the TPU pads only decelerate the stroke end, so add an external rod lock or pilot check valve for suspension. The CA back cover provides a pivot point, and you can pair the internal magnet with CMSG or EMSG sensors for precise end-of-stroke detection.
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 MI20X50SCA 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 or the valve is centred; the fixed TPU bumpers only decelerate the stroke end and do not act as a brake. Use an external rod lock or pilot check valve for holding. The CA designation means it has a rear pivot clevis for articulated mounting.
