Airtac MI16-20 Stainless Steel Mini Cylinder MI16X15SU
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X15SU is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 15mm 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 MI16X15SU
Generating 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles short 15 mm strokes with precision. The riveted barrel and rod resist mild corrosion, making it highly suitable for damp production zones where painted alternatives degrade. Its built-in piston magnet (-S) directly supports CMSG, DMSG and EMSG reed or electronic switches for exact position detection.
Because the 1/8" ported bore yields roughly 10.2 kgf of theoretical push at 0.5 MPa, halving that for a 2:1 safety margin means it reliably lifts about 5.1 kg vertically. Plan for approximately 60 N of actual work at 0.5 MPa rather than the absolute maximum. The U-style 90-degree rear cover simplifies side-mounting in tight assemblies, while the ISO 6432 mounting dimensions ensure it drops straight into standard mini-cylinder brackets.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X15SU Is Used
Short-Stroke Part Clamping
Ideal for gripping small aluminium brackets on a CNC machining line, using its 15 mm travel and 100.5 N thrust to secure parts during milling.
Package Diverter Gate
Actuates a short routing flap on a packaging conveyor to sort lightweight cartons, benefiting from the stainless build in washdown areas.
PCB Pusher Assembly
Advances printed circuit boards into a testing fixture with precise 15 mm movements, using CMSG sensors to confirm the push stroke.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X15SU the Right Cylinder?
When sizing this 15 mm stroke unit, the Ø16 bore sits comfortably between the smaller Ø12 (56.5 N push @0.5 MPa) and the larger Ø20 (157.0 N push @0.5 MPa). If your payload is lighter, stepping down to Ø12 saves space; if you need to shift heavier jigs, Ø20 provides the extra thrust. Keep in mind that venting the air causes the piston to drift, as the fixed TPU bumper pads only decelerate the stroke end rather than locking the rod. To suspend a load safely mid-cycle, fit an external rod lock or a pilot-operated check valve.
The compact 15 mm stroke minimizes rod-bending side loads, which is ideal for tight clamping actions. You can mount the body via LB foot brackets, FA flanges, or TC trunnions, and the included magnet means it is fully ready for sensor integration. For high-speed cycles requiring adjustable end-cushioning, consider the MIC variant instead of this fixed-bumper build.
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 MI16X15SU FAQ
This double-acting cylinder features a 1/8" air port and a 6 mm piston rod. It generates 100.5 N push and 86.4 N pull at 0.5 MPa, 140.7 N push and 120.9 N pull at 0.7 MPa, with a theoretical maximum force of 20.5 kgf at 1.0 MPa.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper pads only soften the impact at the stroke end and do not act as a brake. To maintain a vertical position, you must install an external rod lock or pilot check valve.
