About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X275SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles a 275 mm travel distance with a robust Ø20 mm round-body design. The riveted stainless barrel and rod naturally resist mild corrosion, giving it a distinct advantage over painted alternatives in damp or washdown settings. Because the bore falls within the Ø8-Ø25 range, it utilizes the ISO 6432 mounting interface, dropping smoothly into standard mini-cylinder brackets.
The built-in piston magnet allows direct mounting of CMSG, DMSG or EMSG switches for position sensing. Fixed TPU bumper pads absorb the impact at stroke extremes without adding bulk. For practical sizing, plan for roughly 94 N of actual work at 0.5 MPa, which translates to lifting about 8 kg vertically with a safe 2:1 margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X275SCA Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using the 157 N thrust to push cardboard cartons onto an adjacent belt at high speed.
Lab Sample Ejection
Extends 275 mm to push prepared test tubes out of a centrifuge carousel in a humid clinical environment, relying on the stainless body for corrosion resistance.
Bin Tilt Release
Triggers the latch on a pivoting parts bin, where the CA clevis accommodates the angular swing as the heavy container opens.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X275SCA the Right Cylinder?
When sizing this unit, the Ø16 bore below offers 100.5 N push at 0.5 MPa, while the Ø25 bore above steps up to 245.3 N, letting you fine-tune the force class to the exact payload. The CA rear pivot cover is ideal for clevis mounting, accommodating articulation through the 275 mm travel. Because the stroke is relatively long, carefully manage side loading to prevent rod bending and premature seal wear.
Remember that the fixed TPU pads only decelerate the end-of-stroke impact; they do not function as a lock. If air pressure drops or the valve is centered, the piston will drift. To suspend a load safely during an air loss event, 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 MI20X275SCA 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 is 1/8" and the male rod thread is M8x1.25.
Yes, the -S suffix denotes a built-in piston magnet compatible with CMSG, DMSG and EMSG switches. The CA back cover provides a pivot clevis mount for articulating loads. It also conforms to ISO 6432 mounting dimensions for standard brackets.
