About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X185SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles medium-duty automation with ease. The Ø20 mm bore uses a 1/8" air port and an M8x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. Fixed TPU bumper pads absorb the impact at stroke ends, decelerating the piston smoothly without the complexity of adjustable cushioning.
For practical sizing, plan for about 94 N of real work at 0.5 MPa, which means this actuator lifts roughly 8 kg vertically with a safe 2:1 margin. Because the code includes an S, it features a built-in piston magnet for CMSG, DMSG, or EMSG switches. The CA back cover provides a pivot clevis mount, and the body conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X185SCA Is Used
Package Diverter Gate
Actuates a routing flap on a packaging line, using the 157 N push force to redirect cartons at high speed without stalling.
Textile Loom Tensioner
Pivots via the CA clevis to maintain yarn tension, relying on the stainless build to withstand humid manufacturing conditions.
Bin Lid Lifter
Raises access hatches on material bins, comfortably lifting 8 kg lids vertically through its 185 mm stroke using a 2:1 safety margin.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X185SCA the Right Cylinder?
When sizing this 20 mm bore, stepping down to a 16 mm bore drops the push force to 100.5 N at 0.5 MPa, while moving up to a 25 mm bore increases it to 245.3 N. If your application requires position holding, remember that a plain double-acting cylinder drifts when air is lost or the valve is centered; the TPU bumpers only soften the stroke end and do not act as a brake. For secured loads, install an external rod lock or a pilot-operated check valve.
With a 185 mm stroke, be mindful of side loads and rod bending—ensure the load is guided to prevent premature seal wear. The CA rear pivot cover is ideal for articulating mechanisms, and the -S magnet allows seamless integration with reed or electronic sensors for end-of-stroke confirmation.
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 MI20X185SCA 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 size is 1/8".
Yes to the sensor; the -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG switches. No to the cushion; this model uses fixed TPU bumper pads to decelerate the stroke end, not an adjustable air cushion.
