Airtac MI16-20 Stainless Steel Mini Cylinder MI16X20SCA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X20SCA is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 20mm 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 MI16X20SCA
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation with ease. The riveted Ø16 mm barrel and rod resist mild corrosion, making it highly suitable for damp or washdown environments where painted alternatives fail. Because the bore falls within the Ø8-Ø25 range, it uses the ISO 6432 mounting interface, dropping directly into standard mini-cylinder brackets and clevises.
The integrated piston magnet (-S) supports CMSG, DMSG, and EMSG reed or electronic switches for precise position sensing. Fixed TPU bumper pads decelerate the piston at the stroke ends, while the CA rear pivot cover allows straightforward angular alignment. For practical sizing, plan for a safe working load of about 60 N, which equates to lifting roughly 5.1 kg vertically with a 2:1 safety margin. Air connects via a 1/8" port.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X20SCA Is Used
Component Ejection
Pushes small machined metal parts out of a CNC lathe chuck using a 60 N safe working load, leveraging the short 20 mm stroke for tight machine envelopes.
Flap Folding
Actuates a cardboard box side-flap folder on a washdown-capable packaging line, where the stainless construction prevents mild corrosion from adhesive moisture.
Diverter Gate
Pivots a lightweight sorting deflector on a conveyor using the CA clevis mount, with the -S magnet triggering a DMSG sensor to confirm the gate position.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X20SCA the Right Cylinder?
When sizing this 16 mm bore unit, the smaller Ø12 MI generates 56.5 N of push at 0.5 MPa, whereas stepping up to the Ø20 MI yields 157.0 N. This makes the 100.5 N output of the current model an optimal middle ground for moderate force requirements. The 20 mm stroke keeps the retracted length extremely short, minimizing rod bending and side-load risks that often plague longer actuators.
The CA pivot clevis is ideal for articulating mechanisms, but remember that a standard double-acting cylinder drifts if air pressure is lost or the valve is centered. The TPU bumpers only soften the end-of-stroke impact and do not function as a locking brake. To suspend a load safely during an emergency stop, fit an external rod lock or a pilot-operated check valve.
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 MI16X20SCA FAQ
This double-acting cylinder has a 1/8" air port and an M6x1.0 male rod thread. It generates 100.5 N push and 86.4 N pull at 0.5 MPa, 140.7 N push and 120.9 N pull at 0.7 MPa, with a theoretical maximum force of 20.5 kgf at 1.0 MPa.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. For vertical loads, you must install an external rod lock or pilot check valve. The -S magnet allows CMSG/DMSG/EMSG sensors to track position.
