Airtac MI16-20 Stainless Steel Mini Cylinder MI20X125CM
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X125CM is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 125mm 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 MI20X125CM
Delivering 157 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles mid-range automation tasks with confidence. The stainless-steel barrel and piston rod resist mild corrosion, making it highly suitable for damp production areas where painted steel or aluminium bodies degrade. Its riveted construction keeps the unit compact, while the CM round end cover offers a clean rear profile for straightforward port and mounting orientation. A 125 mm stroke provides ample travel for ejecting parts or actuating small gates.
Built to the ISO 6432 mounting interface, the Ø20 mm body drops directly into standard mini-cylinder brackets and clevises, simplifying retrofits. The 1/8 inch port supplies air efficiently for rapid cycling between 30 and 800 mm/s. Fixed TPU bumper pads absorb the impact at stroke extremes to protect internal components, though they decelerate rather than cushion adjustably. For position feedback, note this specific SKU lacks the -S magnet and therefore cannot host CMSG, DMSG or EMSG switches. In practical terms, plan for roughly 94 N of usable work at 0.5 MPa, which means it can vertically lift about 8 kg safely with a 2:1 margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X125CM Is Used
Package Diverter Gate
Pivots lightweight routing flaps on a packaging conveyor to sort small cartons, utilising the 125 mm stroke to clear the belt path fully.
Small Part Ejector
Pushes machined plastic components out of a fixture on an assembly line, applying the 157 N push force to break a light vacuum grip.
Lab Sample Pusher
Advances test tubes into a heating block, where the stainless-steel construction resists humidity and the CM round end fits tight enclosures.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X125CM the Right Cylinder?
When sizing this 20 mm bore actuator, compare your actual load against the 131.9 N pull force at 0.5 MPa. If your application requires less thrust, dropping down to the Ø16 bore provides 100.5 N push and 86.4 N pull, whereas moving up to the Ø25 bore yields 245.3 N push and 206.1 N pull for heavier mechanisms. The 125 mm stroke is well within the 500 mm maximum, but at this travel length ensure your mounting arrangement—whether LB foot, FA flange or TC trunnion—prevents rod side-loading to avoid premature seal wear.
Because this is a standard double-acting cylinder, it will not hold its position if air pressure drops or the control valve is centred; the piston will drift. The TPU bumpers only soften the end-of-stroke impact and act purely as decelerators, never as a mechanical lock. If your mechanism sags when unpowered, integrate an external pilot-operated check valve or a dedicated rod lock. Additionally, this non-magnetic SKU cannot accept position sensors; you must specify an MI20X125S-CM variant with a magnet to use CMSG, DMSG or EMSG reed switches.
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 MI20X125CM FAQ
This 20 mm bore cylinder features a 1/8 inch air port and an M8x1.25 male rod thread. At 0.5 MPa it generates 157 N push and 131.9 N pull. At 0.7 MPa it generates 219.8 N push and 184.7 N pull. The theoretical maximum force is 32 kgf at 1.0 MPa.
Yes, the Ø20 mm body conforms to ISO 6432 mounting dimensions, so it fits standard mini-cylinder clevises and flanges. However, because this specific SKU lacks a magnet, it cannot accept CMSG, DMSG or EMSG sensors; you would need the -S variant for position detection.
