About the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X20SCATC
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation tasks with ease. The riveted barrel and rod resist mild corrosion, making it a superior choice over painted alternatives in damp or washdown-prone environments. Its 20 mm stroke and 1/8" port provide rapid, precise movement for tight assemblies.
Featuring an ISO 6432 mounting interface, the unit drops directly into standard mini-cylinder brackets and clevises for straightforward design integration. The built-in -S piston magnet supports CMSG, DMSG and EMSG switches for position sensing, while fixed TPU bumper pads absorb end-of-stroke impacts. For practical sizing, plan for a safe working load of about 60 N, which means it can comfortably lift a 5.1 kg component vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X20SCATC Is Used
Component Ejection
Pushes small machined aluminium parts out of a CNC chuck using the 100.5 N extend force, with the TC trunnion absorbing angular misalignment.
Flap Folding
Actuates a cardboard carton folding arm during high-speed packaging lines, relying on the stainless body to withstand occasional washdowns.
Divert Gate
Trips a lightweight sorting gate on a conveyor belt, using the integrated magnet to confirm stroke completion via a DMSG sensor.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X20SCATC the Right Cylinder?
When sizing this 16 mm bore option, note the neighbouring capacities: a 12 mm bore provides 56.5 N push at 0.5 MPa, while a 20 mm bore steps up to 157.0 N. This model includes a CA rear pivot cover and a TC trunnion mount, offering angular alignment flexibility for your mechanical layout. Because the -S magnet is present, you can directly mount CMSG, DMSG or EMSG sensors without further modification.
Remember that standard pneumatic operation allows the piston to drift if air pressure drops or the valve is centred; the TPU bumpers only decelerate the stroke end and do not function as a braking lock. To suspend a load safely during an emergency stop, incorporate an external pilot-operated check valve or a dedicated rod lock. Even with a short 20 mm stroke, minimize side-loading to prevent premature rod seal wear.
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 MI16X20SCATC FAQ
This 16 mm bore cylinder features a 1/8" port and generates 100.5 N push / 86.4 N pull at 0.5 MPa, and 140.7 N push / 120.9 N pull at 0.7 MPa. The theoretical maximum force is 20.5 kgf at 1.0 MPa.
No, the base MI uses fixed TPU bumper pads that decelerate the stroke end but are not adjustable air cushions; for variable cushioning, look at the MIC variant. This model does include an -S magnet for CMSG/DMSG/EMSG sensors and uses an ISO 6432 mounting interface.
