Airtac MI16-20 Stainless Steel Mini Cylinder MI20X210U
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X210U is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 210mm 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 MI20X210U
Delivering 157 N of push force at 0.5 MPa, the AirTAC MI20X210U is a double-acting round-body mini cylinder built for demanding 20 mm bore tasks. The stainless-steel barrel and Ø8 mm piston rod shrug off mild corrosion, giving it a real edge over painted-steel alternatives in damp or washdown-prone environments. Its riveted construction keeps the unit compact, while fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning. The U suffix denotes a 90-degree rear cover, orienting the 1/8 inch port neatly for tight machinery layouts.
Because the 210 mm stroke is well within the 500 mm maximum, it behaves predictably, but plan for a safe working load of roughly 94 N rather than maxing out the rating. This translates to lifting about 8 kg vertically with a sensible 2:1 safety margin. The ISO 6432 mounting interface means it drops straight into standard mini-cylinder brackets and clevises. Note that this specific SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors without switching to an -S variant.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X210U Is Used
Package Diverter Arm
Uses the 157 N push force to swing a lightweight routing gate on a packaging line, with the 90-degree U cover providing a tidy pivot mount in a confined space.
Lab Sample Ejector
Leverages the 210 mm stroke to push test tubes completely clear of a centrifuge hub, relying on the stainless steel rod to resist chemical spills and daily washdowns.
Bin Lid Actuator
Raises and lowers a hinged access hatch on a sorting bin, lifting an 8 kg lid safely while the fixed TPU bumpers prevent jarring impacts at the open and closed positions.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X210U the Right Cylinder?
When sizing this 20 mm bore actuator, compare it directly against its neighbours: a 16 mm bore yields 100.5 N of push at 0.5 MPa, whereas stepping up to a 25 mm bore provides 245.3 N. Choose the MI20X210U when your application sits comfortably in the 94 N safe working zone. The 210 mm stroke is substantial for a mini cylinder, so ensure your guiding structure prevents side-loading and rod bending over that extension length.
This model features the U-style 90-degree back cover, which dictates how the rear pivot and 1/8 inch air port are oriented. Remember that a plain double-acting cylinder drifts if air pressure drops or the valve is centred—the TPU bumpers only decelerate the end of stroke and act as neither a lock nor a brake. To suspend a load safely mid-cycle, fit an external rod lock or a pilot-operated check valve.
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 MI20X210U FAQ
The 20 mm bore generates 157 N push and 131.9 N pull at 0.5 MPa, or 219.8 N push and 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa. The air port size is 1/8 inch.
No, this specific SKU does not include a magnet, so CMSG, DMSG or EMSG switches cannot be used. You must select an -S variant of the MI cylinder to enable position sensing. It uses the ISO 6432 mounting interface and fixed TPU bumper pads rather than an adjustable air cushion.
