Airtac MI16-20 Stainless Steel Mini Cylinder MI20X75R
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X75R is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 75mm 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 MI20X75R
Delivering 157 N of push force at 0.5 MPa, the AirTAC MI20X75R is a double-acting round-body mini cylinder built for compact automation. Its stainless-steel barrel and Ø8 mm rod shrug off mild corrosion, giving it a real edge over painted steel in damp or washdown environments. The riveted construction keeps the body light, while fixed TPU bumper pads absorb the impact at stroke end. This specific SKU features an R back cover, orienting the air supply axially into the rear cap to save side clearance.
Because the Ø20 mm bore falls within the ISO 6432 mounting range, this unit drops directly into standard mini-cylinder brackets and clevises without custom hardware. For practical sizing, plan for a safe working load of about 94 N—roughly 60 percent of the 0.5 MPa rating—rather than pushing the absolute maximum. Similarly, it lifts about 8 kg vertically when you apply a 2:1 safety margin to the 0.5 MPa thrust. Note that this version lacks the -S magnet, so it cannot host CMSG, DMSG or EMSG reed switches.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X75R Is Used
Package Diverter Gate
Actuates a lightweight routing flap on a packaging line, using the 157 N thrust to push corrugated cartons onto an adjacent belt at high speed.
Lab Sample Ejector
Ejects processed fluid vials from a test carousel; the stainless construction resists chemical mist, while the axial R rear port keeps the manifold compact.
Tote Pusher Arm
Advances small plastic totes 75 mm onto a pickup station, safely lifting parts under 8 kg without exceeding the calculated vertical margin.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X75R the Right Cylinder?
When sizing this 75 mm stroke model, compare it against its neighbours: step down to a Ø16 bore for roughly 100 N of push at 0.5 MPa, or move up to a Ø25 bore if you need 245 N to overcome higher friction. The 1/8" port matches the Ø20 bore standard, ensuring adequate flow for the 30-800 mm/s speed range. If your mechanism requires position feedback, select the -S magnet variant instead, as this plain SKU cannot accept a sensor.
Remember that a standard double-acting cylinder drifts when air pressure drops or the valve centres—the TPU bumpers only decelerate the end of travel, acting neither as a lock nor a brake. To suspend a load safely mid-stroke, fit an external rod lock or a pilot-operated check valve. For this 75 mm stroke, keep the load guided to prevent side-loading and rod bending.
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 MI20X75R FAQ
The Ø20 mm bore uses a 1/8" air port and an M8x1.25 male rod thread. At 0.5 MPa it pushes with 157 N and pulls with 131.9 N. At 0.7 MPa the push is 219.8 N and the pull is 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa.
Yes, the Ø20 mm bore uses the ISO 6432 mounting interface, so it fits standard LB foot, FA flange, SDB pivot and TC trunnion hardware. However, because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG sensors; you must order the magnet variant for position feedback.
