About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50SCATC
Generating 157 N of push and 131.9 N of pull at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation tasks with ease. The Ø20 mm bore features a 1/8" 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 settings. Because it carries an -S suffix, a built-in piston magnet is included for CMSG, DMSG or EMSG position switches.
The riveted construction keeps the unit light, while fixed TPU bumper pads absorb impact at the stroke ends. For practical sizing, plan for a safe working load of about 94 N, which means it can lift roughly 8 kg vertically with a 2:1 safety margin. The CA rear pivot cover and TC trunnion accessory provide flexible mounting options for complex kinematics.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50SCATC Is Used
Package Diverter Gate
Pushes lightweight cardboard cartons on a packaging line using the 157 N push force, with the TC trunnion absorbing lateral pivot stress.
Textile Loom Tensioner
Maintains thread tension in a humid textile environment where the stainless steel rod shrugs off mild moisture and lint buildup.
Small Parts Ejector
Kicks machined plastic parts out of a mold cavity, relying on the 50 mm stroke and fixed TPU bumpers to decelerate the ejection impact.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50SCATC the Right Cylinder?
When sizing this 50 mm stroke unit, verify your force needs against the 157 N push at 0.5 MPa. If you require less power, the Ø16 bore provides 100.5 N; stepping up to the Ø25 bore yields 245.3 N. The included TC trunnion and CA clevis suit pivoting loads, but remember that a plain cylinder drifts if air pressure drops. The TPU bumpers only soften the end of stroke, so install an external rod lock or pilot check valve if you must hold a vertical load safely in place.
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 MI20X50SCATC FAQ
This double-acting cylinder uses a 1/8" port and generates 157 N push / 131.9 N pull at 0.5 MPa, 219.8 N push / 184.7 N pull at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa.
Yes, the -S suffix means it has a built-in magnet for CMSG, DMSG or EMSG switches. The CA back cover provides a rear pivot point for clevis mounting, and the included TC trunnion allows centerline support, conforming to ISO 6432 mounting dimensions for easy bracket integration.
