Airtac MI16-20 Stainless Steel Mini Cylinder MI20X190SCA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X190SCA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 190mm 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 MI20X190SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles robust linear motion tasks. The Ø20 mm bore operates on a 1/8" port, while the integrated CA rear pivot cover provides a robust clevis mount for articulated linkages. Built with a riveted stainless barrel and rod, it naturally resists mild corrosion and washdown, outlasting painted alternatives in damp environments.
Equipped with a piston magnet (-S), it supports CMSG, DMSG, and EMSG reed or electronic switches for position sensing. Fixed TPU bumper pads absorb end-of-stroke impacts to protect the mechanism. For practical sizing, plan for a safe working load of roughly 94 N, which means this actuator can comfortably lift about 8 kg vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X190SCA Is Used
Package Diverter Arm
Swings a sorting gate on a packaging line using the CA pivot bracket, relying on the stainless body to endure humid washdown environments.
Film Roll Tensioner
Maintains precise tension on a wrapping machine, using the 8 kg vertical lift capacity to counterbalance the material feed smoothly.
Component Ejector
Pushes machined parts out of a fixture at 30-800 mm/s, using the CMSG sensor to confirm the full 190 mm ejection stroke.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X190SCA the Right Cylinder?
When sizing this 190 mm stroke unit, consider the neighboring bores: a Ø16 generates 100.5 N push, whereas a Ø25 yields 245.3 N at 0.5 MPa. The extended 190 mm travel demands careful alignment to prevent rod bending and premature seal wear under side loads. Because the standard ISO 6432 mounting interface drops directly into standard mini-cylinder brackets, integration into existing assemblies is straightforward.
Remember that a basic double-acting cylinder drifts when air pressure is lost or the valve is centered, as the TPU bumpers only decelerate the stroke end without locking the piston. To suspend a load securely during an outage, fit an external rod lock or pilot-operated check valve. The CA back cover adds pivot flexibility for angular movement requirements.
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 MI20X190SCA 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 of 32 kgf at 1.0 MPa.
No, the fixed TPU bumpers only decelerate the stroke end; they do not lock the piston, so the rod drifts if air is lost. For position feedback, the built-in magnet (-S) accepts CMSG, DMSG, or EMSG switches, but you must add an external rod lock or pilot check valve to hold a vertical load.
