Airtac MI16-20 Stainless Steel Mini Cylinder MI16X20R
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X20R is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 20mm 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 MI16X20R
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles short 20 mm strokes with precision. The riveted barrel and rod shrug off mild corrosion, outperforming painted alternatives in damp production areas. Its 1/8" rear axial-in (R) port keeps hose routing tidy when space is tight. Plan for about 60 N of real work at 0.5 MPa, or expect it to lift roughly 5.1 kg vertically with a safe 2:1 margin. Fixed TPU bumper pads absorb stroke-end impact without adjustable cushioning.
Conforming to ISO 6432 mounting dimensions, the Ø16 body drops directly into standard mini-cylinder brackets and clevises. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches; add the -S variant if you require electronic sensing.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X20R Is Used
Clamp Actuation
Drives short-stroke clamping jaws on small CNC fixtures, applying up to 60 N of safe working force to secure light metal components during machining.
Package Diverting
Extends a 20 mm pusher paddle at a packaging line transfer point to knock small cartons onto an adjacent belt using its 100.5 N thrust.
Part Ejection
Ejects molded plastic parts from a tight tooling cavity, utilizing the compact stainless body to fit within dense mold bases.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X20R the Right Cylinder?
When sizing this 20 mm stroke actuator, verify your force needs against the 100.5 N push and 86.4 N pull ratings at 0.5 MPa. If your payload is lighter, stepping down to the Ø12 bore yields 56.5 N of push force, saving space. For heavier drives requiring more thrust, the Ø20 bore provides 157.0 N. Remember that a plain double-acting cylinder drifts if air pressure drops or the valve is centred—the TPU bumpers only decelerate the stroke end, so install an external pilot check valve to suspend a vertical load.
The rear axial-in R cover orientation helps streamline plumbing along the machine frame. You can pair the body with LB foot, FA flange, SDB pivot, or TC trunnion mounts. For higher cycling speeds that need end-of-stroke deceleration, consider the MIC variable cushion variant instead of the fixed bumper design.
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 MI16X20R FAQ
The 1/8" ported Ø16 bore generates 100.5 N push and 86.4 N pull at 0.5 MPa, or 140.7 N push and 120.9 N pull at 0.7 MPa. The theoretical maximum force is 20.5 kgf at 1.0 MPa.
No, this specific SKU does not include a piston magnet, so CMSG, DMSG, or EMSG switches will not function. You must select the -S magnet version for position sensing. It uses fixed TPU bumper pads rather than an adjustable air cushion.
