The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X165SCA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 165mm 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.
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles demanding 20 mm bore tasks. The riveted barrel and rod shrug off mild corrosion, outlasting painted alternatives in damp or washdown settings. A 1/8" port and M8x1.25 male rod thread secure the air and load connections.
Because the -S suffix equips the piston with a magnet, you can mount CMSG, DMSG or EMSG switches for position sensing. Fixed TPU bumper pads absorb stroke-end impact without the tuning an adjustable cushion demands. Plan for roughly 94 N of actual work at 0.5 MPa, which translates to lifting about 8 kg vertically with a 2:1 safety margin.

MI-family variants: MI / MIC (double acting ±cushion), MSI / MTI (single acting push / pull), MID / MICD (double rod ±cushion), MIJ / MICJ (adjustable stroke ±cushion). Back covers CA / U / R / CM. Mounting LB / FA / SDB / TC.
Pivots a sorting flap on a packaging line using the CA clevis, applying 157 N at 0.5 MPa to push cardboard cartons onto a secondary belt.
Adjusts yarn tension arms in a humid textile facility, relying on the stainless steel rod to resist moisture while cycling through the 165 mm stroke.
Swings a label applicator into position, using the built-in magnet and a DMSG sensor to confirm the 165 mm extension before stamping the pallet side.
Sizing across the range, the 16 mm bore below offers 100.5 N push at 0.5 MPa, while the 25 mm bore above steps up to 245.3 N. This 20 mm model fits neatly in the middle for medium-duty cycling. The CA back cover provides a rear pivot for clevis mounting, ideal for articulating mechanisms.
Note that a standard cylinder drifts if air pressure drops or the valve centres; the TPU pads only decelerate the end of stroke and will not lock the load. For vertical or suspended loads, install an external rod lock or pilot-operated check valve. At 165 mm, keep the rod guided to prevent side-load bending.
Quick checklist
This 20 mm bore cylinder features a 1/8" port. It generates 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa.
Yes, it uses the ISO 6432 mounting interface for standard mini-cylinder brackets. The -S magnet allows CMSG, DMSG and EMSG sensors, and the CA back cover adds a pivot clevis mount for angled loads.
