About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X300R
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles demanding 300 mm linear movements. The Ø20 mm bore uses a 1/8 inch air 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 end-of-stroke impact, while the R back cover features a convenient axial-in port orientation.
Because it lacks the -S suffix, this specific SKU cannot host CMSG, DMSG or EMSG magnetic switches. For practical sizing, plan for roughly 94 N of usable work at 0.5 MPa, which translates to lifting about 8 kg vertically with a safe 2:1 margin. The rolled, riveted construction keeps the body compact and light throughout the 300 mm extension.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X300R Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using the 157 N thrust to push parcels weighing up to 8 kg onto secondary tracks.
Lab Sample Ejection
Extends 300 mm to eject processed fluid samples from a test chamber, relying on the stainless rod to endure mildly humid environments.
Tote Pusher Mechanism
Cycles horizontally to index storage totes, using the fixed TPU bumper pads to soften the impact when reaching the full extension.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X300R the Right Cylinder?
This 300 mm stroke sits well within the 500 mm maximum for the Ø20 bore, but the extended length demands attention to side loading; ensure rigid guidance to prevent rod bending over the travel distance. If your task needs less force, the Ø16 bore offers 100.5 N push at 0.5 MPa, whereas stepping up to the Ø25 bore provides 245.3 N for heavier cycles.
The R-type rear cover supplies an axial-in port for tidy plumbing, and the body accepts standard ISO 6432 mounting dimensions for straightforward bracket integration. Remember that venting air or centering the valve causes the piston to drift, as the TPU bumpers only decelerate the stroke end rather than locking the load. To suspend a weight securely mid-cycle, fit an external rod lock or a pilot-operated check valve. Since this unit has no internal magnet, adding position sensing requires switching to an -S variant.
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 MI20X300R FAQ
At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it yields 219.8 N push and 184.7 N pull. The theoretical maximum force is 32 kgf at 1.0 MPa, and the air port size is 1/8 inch.
No, this specific SKU lacks an internal magnet, so it cannot host CMSG, DMSG or EMSG switches. You would need the -S variant for position sensing. It relies on fixed TPU bumper pads for end deceleration and uses standard ISO 6432 mounting dimensions.
