Airtac MI16-20 Stainless Steel Mini Cylinder MI16X300SCM
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X300SCM is a genuine double acting round-body mini air cylinder with a Ø16mm 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 MI16X300SCM
Generating 100.5 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 Ø16 bore uses a 1/8" port and a Ø6 mm piston rod with an M6x1.0 male thread. Because the barrel and rod are stainless, the riveted construction naturally resists mild corrosion in damp manufacturing areas. The built-in magnet (-S) supports CMSG, DMSG and EMSG switches for position detection, while the CM round end cover keeps the rear profile smooth for tight mounting spaces.
For practical sizing, plan for about 60 N of actual work at 0.5 MPa rather than the absolute maximum. This translates to lifting roughly 5.1 kg vertically with a safe 2:1 margin, letting you match the cylinder to real part weights. Fixed TPU bumper pads absorb the impact at the stroke extremes, decelerating the motion without the complexity of an adjustable air cushion.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X300SCM Is Used
Package Diverting Gate
Actuates a lightweight routing flap on a packaging conveyor, using the 100.5 N thrust to push cartons into secondary lanes without stalling.
Lab Sample Ejection
Ejects processed specimen trays from a testing carousel, where the stainless barrel withstands frequent wipe-downs and mild chemical exposure.
Tote Pusher Mechanism
Advances small plastic totes along a gravity roller track, relying on the 300 mm stroke to clear the workstation before retracting.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X300SCM the Right Cylinder?
Sizing this 16 mm bore against its neighbours ensures the right fit: a smaller Ø12 generates 56.5 N of push at 0.5 MPa, whereas stepping up to a Ø20 yields 157.0 N. If your application demands higher kinetic energy at cycle completion, consider the MIC variant which provides a variable air cushion instead of the standard fixed TPU bumpers. The -S magnet on this unit enables direct mounting of CMSG, DMSG or EMSG sensors. For mounting flexibility, the body accepts LB foot, FA flange, SDB pivot and TC trunnion brackets.
Operating across a 300 mm travel distance requires careful attention to side loading. At this length, lateral forces on the extended rod can cause premature wear; ensure the load moves linearly without binding. Furthermore, a standard double-acting cylinder drifts when air pressure is lost or the valve is centred. The bumpers only soften the end-of-stroke impact and do not function as a brake, so integrate an external rod lock or a pilot-operated check valve if you need to hold a load securely mid-stroke.
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 MI16X300SCM FAQ
The Ø16 bore provides a push force of 100.5 N and a pull force of 86.4 N at 0.5 MPa. At 0.7 MPa, push is 140.7 N and pull is 120.9 N. The theoretical maximum force is 20.5 kgf at 1.0 MPa. The air port size is 1/8".
No, it uses fixed TPU bumper pads that decelerate the piston at the stroke ends; it does not have an adjustable air cushion. Additionally, it cannot hold a load if air is lost, as the piston will drift. Use an external rod lock or pilot check valve for position holding.
