About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X135SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles demanding actuation with a 135 mm stroke. The riveted construction and polished rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Because this SKU includes the -S magnet, it is fully ready for CMSG, DMSG or EMSG position switches.
The integrated CA rear pivot cover allows direct clevis mounting, while the 1/8 inch port keeps air delivery efficient. Fixed TPU bumper pads absorb the impact at stroke extremes to protect the mechanism. For practical sizing, plan for roughly 94 N of actual work at 0.5 MPa, which translates to lifting an 8 kg part vertically with a safe 2:1 margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X135SCA Is Used
Package Diverter Gate
Swings a lightweight routing flap on a packaging line, using the CA pivot to handle the side swing while pushing parcels with 157 N at 0.5 MPa.
Textile Loom Tensioner
Adjusts a yarn tensioning roller in a humid manufacturing environment, relying on the stainless rod to prevent corrosion and the 135 mm stroke for full travel.
Bin Lid Actuator
Lifts an 8 kg access hatch on an automated sorting bin, using the integrated magnet to trigger a DMSG sensor when the lid reaches full extension.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X135SCA the Right Cylinder?
When sizing this 20 mm bore, dropping down to an MI16 yields 100.5 N of push at 0.5 MPa, whereas stepping up to an MI25 provides 245.3 N. This 135 mm stroke is well within the 500 mm maximum, though keeping the rod side-load minimized is vital to prevent bending over the travel distance. The CA clevis mount pairs perfectly with pivot brackets.
Remember that venting the air supply or centering the control valve will cause the piston to drift, as the TPU pads only soften the end stops rather than locking the rod. To suspend a load safely mid-stroke, incorporate an external pilot-operated check valve or a dedicated rod lock.
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 MI20X135SCA FAQ
This 20 mm bore cylinder features a 1/8 inch 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.
Yes, the Ø20 bore uses the ISO 6432 mounting interface, dropping directly into standard mini-cylinder brackets and clevises. The -S suffix denotes a built-in piston magnet, enabling the use of CMSG, DMSG or EMSG electronic or reed switches.
