About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X300SCATC
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 300 mm stroke 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. Fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning.
Because the 157 N rating is theoretical, plan for a safe working load of about 94 N in practice. That translates to lifting an 8 kg part vertically with a sensible 2:1 safety margin. The built-in -S piston magnet supports CMSG, DMSG and EMSG switches for position sensing, while the ISO 6432 mounting interface ensures it drops straight into standard mini-cylinder brackets.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X300SCATC Is Used
Packaging Diverter Gate
Pushes lightweight cardboard cartons on a packaging line using its 157 N thrust and 300 mm reach.
Textile Loom Tensioner
Maintains web tension in a humid textile facility, leveraging the stainless build to resist mild corrosion.
Pallet Labelling Arm
Swings a label applicator into position via the CA pivot cover, safely lifting an 8 kg print head assembly.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X300SCATC the Right Cylinder?
When sizing this unit, the neighbouring Ø16 bore offers 100.5 N of push at 0.5 MPa, whereas stepping up to the Ø25 bore yields 245.3 N. This Ø20 mm model sits right in the middle for medium-duty tasks. The CA rear pivot cover and TC trunnion accessory supply robust articulation for the 300 mm travel, though a stroke this long demands careful alignment to avoid rod-bending side loads. If your process requires the load to stay put when air is removed or the valve is centered, note that the piston will drift; add an external rod lock or pilot check valve for secure holding.
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 MI20X300SCATC FAQ
This Ø20 mm bore cylinder features a 1/8" 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 compatible with CMSG, DMSG and EMSG switches. The CA back cover provides a rear pivot point for clevis mounting, and the body conforms to ISO 6432 mounting dimensions for standard mini brackets.
