The AirTAC MI16-20 Stainless Steel Mini Cylinder MI16X125SR is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 125mm stroke, M5×0.8 air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface fits standard ISO 6432 mini-cylinder mounting interfaces.
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles compact automation with ease. The 16 mm bore uses an M5×0.8 port and a 6 mm piston rod, while the 125 mm stroke falls well within the 500 mm standard limit. Its riveted round-body construction shrinks the footprint compared to bulkier alternatives, and the stainless barrel shrugs off mild corrosion in damp environments.
The built-in magnet supports CMSG, DMSG, or EMSG switches for position sensing. Because the rear cover uses an R axial-in port orientation, plumbing stays neatly in line with the body, and the ISO 6432 mounting dimensions let you drop it straight into standard mini-cylinder brackets.

| Max (@1.0 MPa) | 21 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

MI-family variants: MI / MIC (double acting ±cushion), MSI / MTI (single acting push / pull), MID / MICD (double rod ±cushion), MIJ / MICJ (double rod, adjustable stroke ±cushion). Back covers CA / U / R / CM. Mounting LB / FA / SDB / TC.
Uses the 100.5 N push stroke to knock lightweight plastic molded parts out of a machining fixture on an assembly line.
Extends 125 mm to push small cardboard cartons from a main conveyor belt onto a secondary sorting lane.
Secures thin aluminum brackets during a light drilling operation, utilizing the 86.4 N pull force for reliable holding.
If 100.5 N is too much force, the smaller Ø12 bore offers 56.5 N; if you need more muscle, stepping up to the Ø20 bore provides 157.0 N at the same 0.5 MPa. This SKU includes the -S magnet for position feedback, but remember that a standard cylinder drifts when air is removed or a valve is centered, so add an external rod lock or pilot check valve if you need to hold a vertical load safely. With a 125 mm stroke, keep side loads minimized to prevent rod bending.
The fixed TPU bumper pads absorb end-of-stroke impact to protect the mechanism, though they are not an adjustable air cushion. You can mount this unit using LB foot brackets, FA flanges, SDB pivot blocks, or TC trunnions to suit your frame.
Quick checklist
This 16 mm bore cylinder features an M5×0.8 port and generates 100.5 N push / 86.4 N pull at 0.5 MPa, 140.7 N push / 120.9 N pull at 0.7 MPa, and a theoretical maximum of 20.5 kgf at 1.0 MPa.
Yes, the -S suffix denotes a built-in piston magnet, allowing you to mount CMSG, DMSG, or EMSG switches directly onto the round body for precise position detection.
