Airtac MI16-20 Stainless Steel Mini Cylinder MI16X40U
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X40U is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 40mm 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 MI16X40U
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation with ease. The riveted barrel and rod shrug off mild corrosion, making it far superior to painted alternatives in damp production areas. Its 1/8" port and M6x1.0 male rod thread provide robust pneumatic connections for mid-range tasks.
Because the bare 0.5 MPa rating leaves little room for friction losses, plan for a safe working load of about 60 N. That translates to lifting roughly 5.1 kg vertically with a 2:1 safety margin, letting you match the actuator to real part weights. The included 90-degree U back cover simplifies side-mounting, while fixed TPU bumper pads absorb end-of-stroke impacts.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X40U Is Used
Package Diverter Gate
Pushes lightweight cardboard cartons on a packaging line using a 90-degree U cover to pivot the actuator cleanly into the conveyor frame.
Small Part Ejector
Ejects moulded plastic components from a press, utilizing the 40 mm stroke and 60 N safe working load to clear parts quickly.
Bin Lid Actuator
Lifts stainless steel hopper lids up to 5.1 kg in damp washdown zones, relying on the corrosion-resistant barrel to prevent rust.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X40U the Right Cylinder?
When sizing this 16 mm bore, compare it against its neighbours: a 12 mm bore yields 56.5 N of push at 0.5 MPa, whereas stepping up to a 20 mm bore provides 157 N. Choose this model when your payload sits safely under 60 N. Remember that a standard cylinder drifts if air pressure drops or the valve is centred; the bumpers only decelerate the stroke end, so add an external pilot check valve if you must hold a load vertically.
This specific SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG or EMSG reed switches for position sensing. If your sequence requires confirmation of extension, select the -S variant. For high-speed cycles requiring end-deceleration tuning, consider the MIC variable air cushion variant instead of the fixed bumper pads here.
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 MI16X40U FAQ
At 0.5 MPa it provides 100.5 N push and 86.4 N pull. At 0.7 MPa it yields 140.7 N push and 120.9 N pull. The theoretical maximum force is 20.5 kgf at 1.0 MPa. The air port size is 1/8".
No, this specific SKU does not include the -S magnet, so it cannot accept CMSG, DMSG or EMSG switches. You must order the -S variant for position sensing. It uses standard ISO 6432 mounting dimensions for easy bracket integration.
