Airtac MI16-20 Stainless Steel Mini Cylinder MI16X15U
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X15U 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 MI16X15U
Generating about 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles short 15 mm strokes with a compact riveted round body. The Ø16 bore uses a 1/8 inch port and a 6 mm piston rod. Its stainless construction resists mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. The integrated fixed TPU bumper pads absorb stroke-end impact without requiring adjustment.
Because it lacks the -S suffix, this specific SKU cannot accept CMSG, DMSG or EMSG magnetic sensors. For actual work planning, target a safe load of roughly 60 N, which equates to lifting about 5.1 kg vertically with a 2:1 safety margin. The rear U cover provides a 90-degree mounting interface, and the body conforms to ISO 6432 mini-cylinder mounting dimensions for easy bracket integration.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X15U Is Used
Ejector Pins
Ideal for popping small plastic parts out of moulds, utilizing the snappy 15 mm stroke and 100.5 N push to knock components free without damaging the surface.
Clamping Jigs
Secures small electronic housings during ultrasonic welding, using the 90-degree U cover to mount cleanly against the machine subplate.
Gate Diverters
Pivots small sorting flaps on packaging lines, where the stainless steel barrel withstands occasional washdowns better than standard aluminium bodies.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X15U the Right Cylinder?
When sizing this 15 mm stroke actuator, consider the adjacent bores: the smaller Ø12 generates 56.5 N of push at 0.5 MPa, while the larger Ø20 provides 157.0 N, giving you clear scaling options if your 100.5 N requirement shifts. The short 15 mm travel minimizes rod-bending side-load risks. Remember that venting the air supply causes the piston to drift, as the TPU pads only soften the end of travel rather than locking the rod; add a pilot-operated check valve if you need to freeze the load in place. Since this is a non-magnet SKU, position sensing is unavailable unless you upgrade to an -S variant.
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 MI16X15U 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 size is 1/8 inch.
No, this SKU lacks the internal magnet required for switches. You must purchase the -S variant to use CMSG, DMSG or EMSG sensors. It uses fixed TPU bumper pads rather than an adjustable air cushion, and its ISO 6432 mounting dimensions fit standard mini-cylinder brackets.
