Airtac MI16-20 Stainless Steel Mini Cylinder MI20X450SR
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X450SR is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 450mm 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 MI20X450SR
Generating 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles long 450 mm strokes with an 8 mm rod. The 1/8 inch air port feeds the chamber efficiently, while the built-in piston magnet enables CMSG, DMSG or EMSG switches for position sensing. A rear R axial-in port keeps plumbing neatly oriented along the cylinder axis.
Because the stainless barrel and rod resist mild corrosion and washdown, this riveted construction outlasts painted alternatives in damp environments. The fixed TPU bumper pads absorb stroke-end impact without offering adjustable cushioning. For practical sizing, plan for roughly 94 N of actual work at 0.5 MPa, which translates to lifting about 8 kg vertically with a safe 2:1 margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X450SR Is Used
Diverting Flap Control
Actuates routing gates on packaging lines, using the 450 mm stroke to shift products between parallel belts smoothly.
Vertical Parts Ejection
Pushes completed lightweight plastic components up and out of an injection mold cavity, lifting parts under 8 kg safely.
Sample Tray Indexing
Extends to move laboratory sample trays forward by 450 mm in damp environments, relying on the stainless build to resist moisture.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X450SR the Right Cylinder?
When sizing this 20 mm bore, the smaller 16 mm option yields 100.5 N push at 0.5 MPa, whereas the larger 25 mm bore provides 245.3 N. This model uses the ISO 6432 mounting interface, so it drops directly into standard mini-cylinder brackets and clevises. You can utilize LB foot, FA flange, SDB pivot or TC trunnion mounts alongside CA, U, R or CM back covers.
At 450 mm of travel, the 8 mm rod is susceptible to bending if subjected to excessive side loads, so ensure guided load alignment. Remember that a standard cylinder drifts when air is removed or the valve is centered; the TPU pads only decelerate the stroke end and will not lock the load. Install an external rod lock or pilot check valve if you need to hold a vertical position.
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 MI20X450SR FAQ
This 20 mm bore cylinder features a 1/8 inch port and an 8 mm rod. It generates 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum force of 32 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in magnet compatible with CMSG, DMSG and EMSG switches. For impact absorption, it relies on fixed TPU bumper pads that decelerate the piston at the stroke end; it does not have adjustable air cushioning.
