Airtac MI16-20 Stainless Steel Mini Cylinder MI20X300SR
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X300SR 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 MI20X300SR
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 rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Fixed TPU bumper pads absorb the impact at stroke extremes, while the built-in piston magnet (-S) allows direct mounting of CMSG, DMSG, or EMSG switches for position sensing.
When sizing this actuator, plan for a safe working load of roughly 94 N—about sixty percent of the 0.5 MPa rating—to account for friction and real-world dynamics. For vertical lifts, that translates to hoisting an 8 kg mass with a sensible 2:1 safety margin. The rear R cover features an axial-in port orientation, simplifying plumbing in tight installations.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X300SR Is Used
Package Diverter Gate
Pushes lightweight cardboard cartons on a packaging line using 157 N of thrust, with the 300 mm stroke reaching fully across the conveyor belt.
Lab Sample Ejection
Ejects plastic test tube racks from a damp testing chamber, leveraging the stainless steel construction to withstand repeated humidity and washdown cycles.
Parts Descender
Lowers small 8 kg electronic housings vertically between assembly tiers, safely operating within the 2:1 safety margin at 0.5 MPa.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X300SR the Right Cylinder?
This 300 mm stroke sits well within the 500 mm maximum standard stroke for the Ø20 bore, making it a stock-friendly choice for long reaches. If your application requires less force, stepping down to the Ø16 bore provides 100.5 N of push at 0.5 MPa; conversely, moving up to the Ø25 bore yields 245.3 N. Because the 300 mm stroke creates a long lever arm, carefully manage side loading to prevent rod bending and premature seal wear.
The ISO 6432 mounting interface on this Ø20 bore drops directly into standard mini-cylinder brackets and clevises, streamlining spares and design work. Remember that a plain double-acting cylinder drifts when air is lost or the valve is centred—the TPU bumpers only decelerate the stroke end, acting neither as a lock nor a brake. To suspend a load safely during an air failure, integrate 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 MI20X300SR FAQ
This double-acting cylinder has 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.
No, the piston will drift if air is lost or the valve is centred. The fixed TPU bumper pads only decelerate the rod near the stroke end and do not act as a brake. To hold a vertical load securely, you must add an external rod lock or a pilot-operated check valve.
