Airtac MI16-20 Stainless Steel Mini Cylinder MI20X80R
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X80R is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 80mm 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 MI20X80R
Delivering 157 N of push force at 0.5 MPa, the AirTAC MI20X80R is a double-acting round-body mini cylinder built for compact automation. Its stainless-steel barrel and piston rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. The 80 mm stroke operates at 30-800 mm/s, and the 1/8" port feeds the bore efficiently.
Because the Ø20 mm body follows ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises for easy design integration. This specific SKU lacks the -S magnet, so it cannot host CMSG, DMSG or EMSG switches without upgrading to the magnetic variant. Plan for a safe working load of about 94 N (roughly 60% of the 0.5 MPa rating), which translates to lifting an 8 kg part vertically with a 2:1 safety margin. Fixed TPU bumper pads absorb the stroke-end impact, and the R back cover supplies a convenient axial-in port orientation.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X80R Is Used
Package Diverter Gate
Pushes light cardboard cartons on a packaging line using its 157 N thrust, with the stainless body surviving occasional washdowns.
Small Parts Ejector
Ejects machined plastic components from a fixture using the 80 mm stroke, relying on the fixed TPU bumpers to soften the end impact.
Bin Lid Actuator
Opens and closes lightweight access hoppers on material handling stations, where the R axial-in port keeps the air lines tucked away safely.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X80R the Right Cylinder?
When sizing this 20 mm bore, the smaller Ø16 generates 100.5 N of push at 0.5 MPa, while stepping up to the Ø25 yields 245.3 N, giving you clear boundaries if your payload shifts. The 80 mm stroke is well within the 500 mm maximum, but always watch for rod-bending side loads on longer extensions. This R-cover version routes plumbing axially, which helps in tight mounting envelopes alongside LB foot, FA flange, or TC trunnion hardware.
Remember that a standard double-acting cylinder drifts when air is lost or the valve is centred; the TPU bumpers only decelerate the stroke end and do not act as a brake. To hold a load securely mid-stroke, you must add an external rod lock or a pilot-operated check valve to the pneumatic circuit.
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 MI20X80R FAQ
At 0.5 MPa this 20 mm bore cylinder provides 157 N of push force and 131.9 N of pull force. At 0.7 MPa it delivers 219.8 N push and 184.7 N pull, with a theoretical maximum of 32 kgf at 1.0 MPa. It uses a 1/8" air port and an M8x1.25 male rod thread.
No, this specific SKU does not include the -S magnet option, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. It uses standard ISO 6432 mounting dimensions for brackets, and the fixed TPU bumper pads decelerate the stroke end but do not function as an adjustable air cushion.
