Airtac MI16-20 Stainless Steel Mini Cylinder MI20X450SCM
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X450SCM 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 MI20X450SCM
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 450 mm stroke with ease. The Ø20 mm bore operates on a 1/8 inch port, while the male M8x1.25 rod thread secures your tooling. Built with a riveted stainless barrel and rod, it naturally resists mild corrosion and washdown better than painted alternatives. The included piston magnet (-S) directly supports CMSG, DMSG and EMSG sensors for position detection.
For real-world sizing, plan for roughly 94 N of actual work at 0.5 MPa to keep a safe 60 percent margin. This translates to lifting about 8 kg vertically against gravity. The rear CM round end cover cleanly finishes the back, and fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X450SCM Is Used
Packaging Diverter Gate
Actuates a routing flap on a packaging line, using the 8 kg vertical lift capacity to push heavy cardboard cartons onto a secondary belt.
Warehouse Vertical Pusher
Extends 450 mm to index totes on a storage rack, relying on the stainless build to endure humid dock environments.
Textile Yarn Guide
Traverses a thread guide mechanism across a wide loom, with the CMSG sensor tracking the exact end-of-stroke position.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X450SCM the Right Cylinder?
When sizing this 450 mm stroke unit, the Ø16 bore below provides 100.5 N push at 0.5 MPa, whereas the Ø25 bore above steps up to 245.3 N. This model hits a solid middle ground for moderate loads. Because the 450 mm stroke is quite long relative to the bore, carefully manage side loading to prevent rod bending and premature seal wear. The ISO 6432 mounting interface lets you drop this cylinder directly into standard mini-cylinder brackets and clevises.
Remember that venting the air or centering the valve causes the piston to drift, as the fixed bumpers only decelerate the end of travel rather than locking the rod. To suspend a load safely mid-stroke, install an external rod lock or a pilot-operated check valve. You can select LB foot, FA flange, SDB pivot or TC trunnion mounts to fit your frame.
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 MI20X450SCM 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. The air port size is 1/8 inch.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. You must add an external rod lock or pilot check valve to hold a suspended load.
