Airtac MI16-20 Stainless Steel Mini Cylinder MI20X90SCM
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X90SCM is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 90mm 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 MI20X90SCM
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 90 mm stroke with a 1/8" port and an M8x1.25 male rod thread. The rolled stainless barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Its ISO 6432 mounting interface drops directly into standard mini-cylinder brackets and clevises for easy design integration.
Plan for roughly 94 N of actual work at 0.5 MPa, which safely lifts an 8 kg part vertically with a 2:1 margin. The built-in piston magnet supports CMSG, DMSG, and EMSG switches for position sensing, while the CM round rear cover keeps the back port orientation clean and compact. Fixed TPU bumper pads absorb the stroke-end impact to protect your mechanism.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X90SCM Is Used
Package Diverter Gate
Pushes a lightweight routing flap on a packaging line, using the 8 kg vertical lift capacity to reliably redirect small cartons at speed.
Textile Loom Tensioner
Maintains consistent yarn tension in a humid textile environment, where the stainless steel barrel resists mild corrosion from ambient moisture.
Small Part Ejector
Ejects molded plastic components from a tooling fixture, relying on the CMSG sensor magnet to confirm the 90 mm ejection stroke before the mold closes.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X90SCM the Right Cylinder?
When sizing this 20 mm bore, compare it against the 16 mm option (100.5 N push @0.5 MPa) for lighter tasks, or step up to the 25 mm bore (245.3 N push @0.5 MPa) if your mechanism needs more muscle. The 90 mm stroke is well within the 500 mm maximum, keeping the rod bending risk low, but always minimize side loading to preserve the rod seals.
Because the standard MI lacks a physical lock, the piston will drift if air pressure drops or the valve is centered, meaning the bumper pads only decelerate the stroke end rather than holding the load. To suspend a weight securely in place, add an external rod lock or a pilot-operated check valve to 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 MI20X90SCM FAQ
This 20 mm bore cylinder uses 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.
No, the piston will drift if air pressure is lost or the valve is centered. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake; use an external rod lock or pilot check valve to hold a vertical load.
