Airtac MI16-20 Stainless Steel Mini Cylinder MI20X5SCA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X5SCA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 5mm 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 MI20X5SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact actuation with ease. The Ø20 mm bore uses a 1/8" port and an M8x1.25 male rod thread. Its riveted stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. The built-in magnet (-S) directly supports CMSG, DMSG and EMSG reed or electronic switches for position sensing.
For practical sizing, plan for roughly 94 N of real work at 0.5 MPa, which safely lifts an 8 kg part vertically with a 2:1 margin. The CA back cover provides a rear pivot point for clevis mounting. Fixed TPU bumper pads absorb the impact at the 5 mm stroke end, decelerating the piston smoothly without the complexity of an adjustable cushion.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X5SCA Is Used
Clamping Housings
Exerts a safe 94 N working force to hold die-cast aluminium housings firmly in place during a light machining or drilling sequence.
Film Seal Jaw
Drives a short 5 mm stroke to close a vertical form-fill-seal jaw, using the CA pivot to maintain jaw alignment during the rapid packaging cycle.
Diverter Gate
Pivots a stainless deflector plate on a washdown conveyor to route small bottles, relying on the corrosion-resistant stainless build for longevity.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X5SCA the Right Cylinder?
If you need less push, the Ø16 bore yields 100.5 N at 0.5 MPa; if your task requires more power, stepping up to the Ø25 bore provides 245.3 N. This model includes the CA pivot cover and the -S magnet for position sensing. Because the 5 mm stroke is extremely short, side-load stress on the rod is minimal, but you must still align the pivot precisely to avoid binding. Remember that a standard cylinder drifts if air pressure drops or the valve is centred; the bumpers only soften the end of travel and will not lock the load. Use a pilot-operated check valve or an external rod lock if you need to hold a vertical position 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 MI20X5SCA FAQ
This Ø20 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.
Yes, the -S suffix indicates a built-in piston magnet designed for CMSG, DMSG and EMSG switches. The CA back cover provides a rear clevis pivot interface that conforms to ISO 6432 mounting dimensions, allowing easy integration into standard mini-cylinder brackets.
