About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X130SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 130 mm stroke with a CA pivot clevis. The riveted stainless barrel and rod resist mild corrosion, outperforming painted alternatives in damp or washdown settings. Its 1/8" port and M8x1.25 male rod thread ensure straightforward integration.
Because the 157 N rating is theoretical, plan for a real working load of roughly 94 N to account for friction. Vertically, this translates to safely lifting about 8 kg when applying a 2:1 safety margin. The built-in magnet enables CMSG, DMSG, or EMSG sensors for position detection.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X130SCA Is Used
Package Diverter Arm
Actuates a routing flap on a packaging line, using the CA clevis to pivot and push light parcels weighing up to 8 kg smoothly.
Textile Loom Tensioner
Adjusts yarn tensioner blocks in humid textile facilities, relying on the stainless steel rod to withstand continuous damp exposure.
Lab Sample Ejector
Pushes processed test tubes out of a centrifuge carousel, using the 130 mm stroke and position-sensing switches for precise ejection timing.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X130SCA the Right Cylinder?
When sizing this 20 mm bore, the smaller 16 mm option yields 100.5 N push at 0.5 MPa, while the larger 25 mm bore provides 245.3 N. The CA rear clevis suits pivoting linkages, complemented by LB foot, FA flange, or TC trunnion brackets. The -S magnet allows direct switch mounting.
At 130 mm, the stroke is well within the 500 mm maximum, yet side loads still demand careful guide alignment to prevent rod bending. Note that venting air causes the piston to drift; use an external rod lock or pilot check valve to suspend loads safely, as the fixed TPU bumpers only decelerate impact at stroke ends.
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 MI20X130SCA FAQ
This 20 mm bore cylinder features a 1/8" port. 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 of 32 kgf at 1.0 MPa.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper pads only soften the stroke-end impact and do not act as a brake. You must add an external rod lock or pilot check valve to hold loads securely.
