About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X270SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 270 mm stroke with ease. The Ø20 mm bore uses 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 environments.
The built-in piston magnet (-S) supports CMSG, DMSG, and EMSG switches for position sensing. Riveted construction keeps the body compact, while fixed TPU bumper pads decelerate the stroke end. Plan for roughly 94 N of actual work at 0.5 MPa, which means it can safely lift about 8 kg vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X270SCA Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using the 157 N push force to redirect moderate-weight cartons smoothly.
Lab Sample Ejection
Extends 270 mm to push tested specimen trays out of a damp chemical analysis station, relying on the stainless rod for corrosion resistance.
Textile Loom Tensioning
Pivots via the CA clevis to maintain fabric tension, using the 131.9 N pull force at 0.5 MPa to keep material taut during weaving.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X270SCA the Right Cylinder?
This Ø20 mm bore sits between the smaller MI16 (100.5 N push @0.5 MPa) and the larger MI25 (245.3 N push @0.5 MPa). The included CA rear pivot cover provides a clevis mount for angular alignment, complementing available LB foot, FA flange, and TC trunnion options. Because the stroke is 270 mm, ensure your guiding structure handles side loads to prevent rod bending.
Air pressure both extends and retracts the rod, but a standard cylinder drifts when air is lost or a valve is centered. The TPU bumpers only soften impact near the stroke end and do not act as a brake. To suspend a load safely, install an external rod lock or a pilot-operated check valve.
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 MI20X270SCA FAQ
This double-acting cylinder features a 1/8" port and generates 157 N push / 131.9 N pull at 0.5 MPa, and 219.8 N push / 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa.
Yes, the Ø20 mm bore uses the ISO 6432 mounting interface, so it drops directly into standard mini-cylinder brackets and clevises. The -S suffix denotes a built-in magnet for CMSG, DMSG, or EMSG switches.
