Airtac MI16-20 Stainless Steel Mini Cylinder MI16X300R
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X300R 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 MI16X300R
Delivering 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 a 1/8" port. The riveted barrel and Ø6 mm rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Its dimensions follow the ISO 6432 mounting interface, dropping directly into standard mini-cylinder brackets and clevises.
Fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning. Plan for about 60 N of actual work at 0.5 MPa, which means it lifts roughly 5.1 kg vertically with a 2:1 safety margin. The R back cover directs the air supply axially in from the rear, keeping hose routing tight against the machine frame.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X300R Is Used
Package Diverter Gate
Pushes lightweight cardboard cartons on a packaging line using 100.5 N of thrust, with the 300 mm reach clearing the main conveyor belt.
Lab Sample Ejection
Ejects plastic test tube racks from a testing carousel, leveraging the stainless build to resist daily chemical wipe-downs.
Parts Descender
Lowers small stamped metal parts into a machining fixture, safely managing the 5.1 kg vertical lift capacity with a 2:1 margin.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X300R the Right Cylinder?
When sizing this 16 mm bore, the smaller Ø12 generates 56.5 N of push at 0.5 MPa, while stepping up to the Ø20 yields 157 N, giving you clear boundaries if your load shifts. Because this 300 mm stroke is relatively long for a mini cylinder, carefully manage side loading to prevent rod bending and premature seal wear. The bumper pads only decelerate the end of travel; they do not function as a lock. If your application must hold a load vertically when air is removed or the valve is centered, you must add an external rod lock or a pilot-operated check valve to prevent drift.
This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG magnetic switches for position sensing. If you need end-of-stroke feedback, select the -S variant. You can mount the body using LB foot brackets, FA flanges, SDB pivot blocks, or TC trunnions to suit your layout.
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 MI16X300R FAQ
This 16 mm bore cylinder features a 1/8" port and generates 100.5 N push and 86.4 N pull 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.
No, this SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for position sensing. The R back cover provides axial porting, and the body uses fixed TPU bumper pads rather than an adjustable air cushion.
