Airtac MI16-20 Stainless Steel Mini Cylinder MI20X300SCA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X300SCA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 300mm 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 MI20X300SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 300 mm stroke with ease. The Ø20 mm bore uses a 1/8" port and an M8x1.25 male rod thread. Its stainless barrel and piston rod naturally resist mild corrosion, giving it a real edge over painted-steel alternatives in damp or washdown environments. Riveted construction keeps the body compact, while fixed TPU bumper pads absorb the impact at stroke extremes.
Because it conforms to ISO 6432 mounting dimensions, the body drops directly into standard mini-cylinder brackets and clevises. The built-in magnet (-S) supports CMSG, DMSG, and EMSG position switches. For real-world sizing, plan for a safe working load of about 94 N (roughly 60 percent of the 0.5 MPa rating), which means it can vertically lift an 8 kg part with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X300SCA Is Used
Package Diverter Gate
Actuates a routing flap on a packaging line, using the 157 N push force to redirect moderate-weight cartons at high cycling speeds.
Textile Loom Tensioner
Employs the CA clevis mount to pivot a tensioning arm, maintaining fabric tightness while the stainless body resists humid textile mill environments.
Bin Lid Lifter
Raises access hatches on material bins, easily handling the 8 kg vertical lift capacity calculated with a 2:1 safety margin over its 300 mm travel.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X300SCA the Right Cylinder?
When sizing this 300 mm stroke model, compare it against its neighbours: a Ø16 bore gives 100.5 N of push at 0.5 MPa, while stepping up to a Ø25 bore yields 245.3 N. This Ø20 mm model sits perfectly in the middle for moderate force tasks. The CA rear pivot cover provides a clevis mount ideal for articulating linkages. Because a 300 mm stroke amplifies leverage, minimize side-loading to prevent rod bending and premature seal wear. The TPU bumpers decelerate the piston at the ends, but they do not function as a brake; if air pressure drops, the rod will drift. To lock a load mid-stroke, integrate 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 MI20X300SCA FAQ
At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it provides 219.8 N push and 184.7 N pull. The theoretical maximum force is 32 kgf at 1.0 MPa. The air port size is 1/8".
No, the piston will drift if air is lost or the valve is centred. The fixed TPU bumper pads only decelerate the stroke end and do not act as a lock. For suspended loads, install an external rod lock or pilot check valve. The -S magnet allows CMSG/DMSG/EMSG sensors for position feedback.
