Airtac MI16-20 Stainless Steel Mini Cylinder MI16X400SU
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X400SU is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 400mm 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 MI16X400SU
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 400 mm stroke with a 1/8" port and M6x1.0 male rod thread. The rolled stainless barrel and rod shrug off mild corrosion, outlasting painted alternatives in damp or washdown settings. Because the 16 mm bore uses the ISO 6432 mounting interface, it drops directly into standard mini-cylinder brackets and clevises without custom hardware.
Plan for about 60 N of real work at 0.5 MPa, which means this actuator lifts roughly 5.1 kg vertically with a safe 2:1 margin. The U-style 90-degree rear cover simplifies lateral pivot mounting on tight machinery. Fixed TPU bumper pads absorb the impact at stroke extremes, decelerating the piston without the complexity of an adjustable cushion. The built-in -S magnet supports CMSG, DMSG and EMSG position switches for closed-loop control.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X400SU Is Used
Package Diverter Gate
Pivots a routing flap on a packaging line, using the 90-degree U rear cover to mount directly to the conveyor frame and handle lightweight cartons.
Lab Sample Ejection
Pushes prepared specimen trays out of a testing station, where the stainless build resists chemical exposure and the 400 mm stroke clears the workspace.
Parts Sorting Pusher
Transfers small plastic components into sorting bins, relying on the -S magnet and DMSG sensors to confirm full extension before the next cycle.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X400SU the Right Cylinder?
When sizing this 16 mm bore, verify if the 100.5 N push at 0.5 MPa is sufficient or if you need to step up to the 20 mm bore offering 157.0 N; dropping down to the 12 mm bore limits you to 56.5 N. A 400 mm stroke on a 6 mm rod demands careful alignment, as long extensions amplify side-load forces and risk rod bending. Utilize the LB foot, FA flange, SDB pivot block or TC trunnion mounts to support the body and minimize deflection.
Remember that venting the air supply or centering the control valve causes the piston to drift, as the TPU bumpers only soften the end of travel and act as neither a brake nor a lock. To prevent a vertical load from dropping, integrate an external rod lock or a pilot-operated check valve into your 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 MI16X400SU FAQ
The 16 mm 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, with a theoretical maximum of 20.5 kgf at 1.0 MPa. The air port size is 1/8".
No, it uses fixed TPU bumper pads to decelerate the piston at the stroke ends. For adjustable air cushioning, you would need the MIC variant. This model includes a -S magnet for CMSG, DMSG or EMSG switches.
