Airtac MI16-20 Stainless Steel Mini Cylinder MI20X80SCM
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X80SCM is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 80mm 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 MI20X80SCM
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles an 80 mm stroke with a Ø8 mm piston rod. The riveted barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Its 1/8" port feeds air to extend and retract the rod, while fixed TPU bumper pads absorb the impact at stroke ends.
Because it carries an -S magnet, the cylinder accepts CMSG, DMSG, or EMSG switches for position sensing. Plan for roughly 94 N of actual work at 0.5 MPa, which means it can safely lift an 8 kg part vertically with a 2:1 safety margin. The round CM back cover keeps the rear profile smooth, and the ISO 6432 mounting dimensions let you drop it straight into standard mini-cylinder brackets and clevises.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X80SCM Is Used
Package Diverter
Pushes lightweight cardboard cartons on a packaging line using 157 N of thrust, with the stainless build resisting humid washdown environments.
Small Press Ejector
Kicks stamped metal parts out of a die zone, relying on the 80 mm stroke and fixed TPU bumpers to soften the end-of-travel impact.
Vertical Parts Lift
Raises 8 kg electronic housings between conveyor tiers, safely operating within the 2:1 load margin of its 0.5 MPa rating.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X80SCM the Right Cylinder?
If 157 N of push at 0.5 MPa is too much, step down to the Ø16 bore that yields 100.5 N; if you need more muscle, the Ø25 bore pushes 245.3 N. Remember that a standard double-acting cylinder like this drifts if air pressure drops or the valve is centered—the TPU bumpers only decelerate the stroke end, so add an external rod lock or pilot check valve if you must hold a vertical load. The built-in magnet pairs directly with CMSG, DMSG, or EMSG sensors, and the CM round rear cover suits tight installations. At 80 mm, side loads are minimal, but always guide the rod to prevent bending on longer extensions.
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 MI20X80SCM FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N. At 0.7 MPa it pushes 219.8 N and pulls 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa. Air connects via a 1/8" port, and the male rod thread is M8x1.25.
Yes, the -S suffix means it has a built-in piston magnet for CMSG, DMSG, or EMSG switches. However, it does not hold position on air loss; the piston drifts, and the fixed TPU bumper pads only decelerate the stroke end. Use an external rod lock for holding.
