The AirTAC AirTAC MA16X20SU Mini Cylinder, 16 mm Bore is a genuine double acting standard round-body mini air cylinder with a Ø16mm bore and 20mm stroke, M5×0.8 air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
The MA16X20SU combines a 16 mm bore with a 20 mm stroke in AirTAC's riveted round-body mini series, closed by a flat-end U back cover that presents a clean fixed face for bracket work. It is double acting, so air both extends and retracts the 6 mm rod, and fixed anti-impact bumper pads soften each stroke end. Ports are M5x0.8 PT on a stainless-steel barrel with a hard-chrome plated carbon-steel piston rod. Output is 100.5 N on the push stroke at 0.5 MPa and 86.4 N on the return, scaling to 140.7 N at 0.7 MPa. Plan on about 60 N of genuine working effort, so the rod will lift roughly 5 kg vertically with a 2:1 margin. The stainless barrel and chrome rod shrug off damp and washdown spots where painted-steel minis corrode, and the magnet is built in as standard, so CMSG, DMSG or EMSG switches drop on without special ordering.

Specifications follow the official AirTAC MA-series datasheet. Barrel: stainless-steel tube (round-body, riveted rolling-packed construction); piston rod: carbon steel with 20µm hard-chrome plating; covers: aluminium alloy. Thread options: PT (blank) / G / NPT. Every MA-series cylinder ships with a built-in magnet for CMSG / DMSG / EMSG position sensors.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 101 N | 86 N |
| 0.7 MPa | 141 N | 121 N |
| Max (@1.0 MPa) | 21 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

|---|---|
| 16 | Bore size in mm. |
| ×20 | Stroke length in mm. |
| -S | Built-in magnet for CMSG / DMSG / EMSG sensors (standard on MA series). |
| CA / U / CM | Back-cover type: CA pivot, U flat-end, CM round-end. |
MA-family variants: MA / MAC (double acting ±cushion), MSA / MTA (single acting push / pull), MAD / MACD (double rod ±cushion), MAJ / MACJ (adjustable stroke ±cushion), MAR (cushioned with integrated F/U mount). Mounting accessories: FA flange, LB foot, SDB pivot; plus I and Y knuckles. Thread PT (blank) / G / NPT.
The 20 mm stroke clears a small connector from its nest, and 100.5 N push at 0.5 MPa is ample for light electronic housings, with M5x0.8 ports keeping tubing slim.
With roughly 5 kg of vertical margin, the flat-end U cover bolts flat against a guarding plate to press caps home until the labeler cycle picks up.
A CMSG or DMSG switch on the standard magnet confirms open and closed positions as the rod raises a lightweight fixture guard between test runs.
At 16 mm this is the smallest bore in the MA line - 100.5 N push at 0.5 MPa covers light clamps, chute diverters and small-part ejection. If the load needs more muscle, the next size up, a 20 mm bore, delivers 157.0 N under the same pressure. A plain MA will not park the rod where you leave it: once the valve centres or air drops, the piston drifts, so fit a pilot check valve or rod lock for any suspended load. The U flat-end back cover mounts flush against a machine face, while FA flange, LB foot or SDB pivot brackets can be added as the layout demands. The magnet comes fitted as standard for CMSG / DMSG / EMSG position sensing.
Quick checklist
At 0.5 MPa the push force is 100.5 N and the pull force is 86.4 N; at 0.7 MPa push reaches 140.7 N. Theoretical maximum output is 20.5 kgf at 1.0 MPa. The cylinder is double acting, runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), cycles at 30-800 mm/s and uses an M6x1.0 male rod thread.
No. The stroke ends carry fixed anti-impact bumper pads that simply soften impact; the MA series has no adjustable air cushion. Where tunable end-position deceleration is required, the related MAC cylinders provide that feature and also add larger bores.
