About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X45SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation with ease. The Ø20 mm bore operates on a 1/8" port and features a CA pivot clevis back cover for straightforward articulated mounting. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments.
Equipped with a built-in magnet (-S), the unit supports CMSG, DMSG, and EMSG switches for position sensing. The ISO 6432 mounting interface drops directly into standard mini-cylinder brackets. For practical sizing, plan for a safe working load of about 94 N, which means it can comfortably lift an 8 kg part vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X45SCA Is Used
Package Diverter Arm
Articulated via the CA clevis, this cylinder swings a diverter gate on a packaging line, using its 8 kg vertical lift capacity to reliably redirect lightweight cartons.
Small Parts Ejector
Pushes machined components out of a fixture with 157 N of force at 0.5 MPa, relying on the CMSG sensor to confirm the ejection stroke before the next cycle.
Lab Sample Handler
The stainless construction survives mildly corrosive lab environments, moving sample trays with a 45 mm stroke while the fixed TPU bumpers prevent harsh end-of-stroke impacts.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X45SCA the Right Cylinder?
When sizing this model, note the smaller Ø16 bore provides 100.5 N of push at 0.5 MPa, while the larger Ø25 bore offers 245.3 N, allowing you to step up or down if 157 N is borderline. The 45 mm stroke keeps the rod compact, minimizing bending moments, while the fixed TPU bumper pads decelerate the stroke end without offering adjustable cushioning. Because this SKU includes the -S magnet, you can directly mount CMSG, DMSG, or EMSG sensors.
Remember that a standard double-acting cylinder drifts when air is lost or the valve is centered, as the bumpers only soften impact rather than locking the rod. To suspend a load safely during an air failure, integrate an external rod lock or a pilot-operated check valve into your circuit.
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 MI20X45SCA FAQ
This Ø20 mm cylinder uses a 1/8" port and generates 157 N push / 131.9 N pull at 0.5 MPa, and 219.8 N push / 184.7 N pull at 0.7 MPa. Its theoretical maximum force is 32 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in piston magnet compatible with CMSG, DMSG, and EMSG switches. It also features a CA pivot clevis back cover and conforms to ISO 6432 mounting dimensions for standard mini-cylinder brackets.
