Airtac MI16-20 Stainless Steel Mini Cylinder MI20X350CA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X350CA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 350mm 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 MI20X350CA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 350 mm stroke with a CA rear pivot cover. The 1/8" port feeds the 20 mm bore, while fixed TPU bumper pads absorb the end-of-stroke impact. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings.
Because the 20 mm bore falls within the Ø8-Ø25 range, the body uses the ISO 6432 mounting interface, dropping directly into standard mini-cylinder brackets and clevises. Plan for about 94 N of actual work at 0.5 MPa, which means it lifts roughly 8 kg vertically with a 2:1 safety margin. Note this SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG switches without switching to an -S variant.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X350CA Is Used
Package Diverter Arm
Swings a lightweight routing gate on a packaging line, using the CA pivot to absorb angular stress while pushing 157 N at 0.5 MPa.
Lab Sample Ejector
Extends 350 mm to push test tubes out of a washdown chamber, relying on the stainless rod to shrug off mild chemical exposure.
Tote Pusher
Cycles horizontally to nudge small plastic totes off a roller track, lifting or pushing up to 8 kg safely with a 2:1 margin.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X350CA the Right Cylinder?
When sizing this actuator, the neighbouring 16 mm bore yields 100.5 N of push at 0.5 MPa, whereas stepping up to the 25 mm bore provides 245.3 N. The 350 mm stroke is well within the 500 mm maximum for this bore, but extending a rod this far increases side-load risk; ensure your front mounting guides the load to avoid bending the 8 mm rod. The CA back cover supplies a rear pivot point for angular alignment.
Air pressure alone will not sustain a load if the valve is centred or supply drops, as the piston will drift and the TPU pads only soften the stroke end rather than locking it. For suspended loads, fit an external rod lock or a pilot-operated check valve. This specific unit has no internal magnet, ruling out position sensing unless you specify an -S model.
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 MI20X350CA FAQ
This 20 mm bore cylinder features a 1/8" port and an M8x1.25 male rod thread. 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 of 32 kgf at 1.0 MPa.
Yes, the 20 mm bore uses the ISO 6432 mounting interface for easy bracket fitment, and the CA cover provides a rear clevis pivot. However, this SKU lacks a magnet, so you cannot mount CMSG, DMSG or EMSG switches without selecting the -S variant.
