Airtac MI16-20 Stainless Steel Mini Cylinder MI16X40SUTC
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X40SUTC 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 MI16X40SUTC
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation tasks with ease. The riveted stainless barrel and Ø6 mm rod shrug off mild corrosion, making it a hardier choice than painted alternatives in damp production areas. Because the bore is Ø16, it uses the ISO 6432 mounting interface, so it drops directly into standard mini-cylinder brackets and clevises.
The built-in piston magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing, while the U 90-degree back cover and TC trunnion mounting provide flexible pivot orientation. It breathes through a 1/8 inch port and relies on fixed TPU bumper pads to decelerate the stroke end. Plan for roughly 60 N of actual work at 0.5 MPa, which means it lifts about 5.1 kg vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X40SUTC Is Used
Package Diverter Gate
Pushes light cardboard cartons on a packaging line using its 100.5 N thrust and 40 mm stroke.
Small Part Clamp
Secures plastic housings for machining, utilising the TC trunnion to pivot the clamping arm.
Bin Lid Actuator
Pivots a 90-degree U cover to open sorting bins, with the -S magnet confirming lid closure.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X40SUTC the Right Cylinder?
If you need less force, the Ø12 bore provides 56.5 N push at 0.5 MPa; stepping up to the Ø20 bore yields 157.0 N. This 40 mm stroke sits well within the 500 mm maximum, keeping rod bending stress low. The TC trunnion pairs with the U back cover for pivoting loads, but remember the piston will drift if air pressure drops. For vertical loads that must stay put during air loss, add an external rod lock or pilot check valve.
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 MI16X40SUTC FAQ
At 0.5 MPa it pushes 100.5 N and pulls 86.4 N. At 0.7 MPa it pushes 140.7 N and pulls 120.9 N. The theoretical maximum force is 20.5 kgf at 1.0 MPa. The air port is 1/8 inch.
No, the piston drifts if air is lost; use an external rod lock for holding. It has fixed TPU bumper pads to decelerate the stroke end, not an adjustable air cushion. The -S magnet allows CMSG, DMSG and EMSG sensors.
