The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X165SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 165mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service. A variable air cushion at both ends lets you tune end-of-stroke deceleration on site.
Where a fixture plate needs a flat face to bolt against, the MAC20X165SU answers with its U flat-end back cover and 165 mm of standard stroke. It is a 20 mm bore, double-acting mini cylinder with a variable air cushion at each end, pushing 157 N and pulling 132 N at 0.5 MPa on 0.15-1.0 MPa (22-145 psi) air, at speeds from 30 to 800 mm/s.
The stainless barrel is rolled and riveted over aluminium covers, a construction that survives humid plants and rinse-down corners where painted minis bubble and pit. Because the magnet ships inside every piston, CMSG, DMSG and EMSG switches snap on without ordering a special version. Budget around 94 N for the working part of the cycle at 0.5 MPa, and remember the same force holds about 8 kg vertically once you apply a 2:1 margin.

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 | 157 N | 132 N |
| 0.7 MPa | 220 N | 185 N |
| Max (@1.0 MPa) | 32 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

| 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.
Face-mount the flat-end cover to a feeder and eject finished parts off a nest every cycle, with the cushion absorbing each rapid strike.
Raise a powder sampling probe through a drum vent - the 165 mm stroke clears the rim and the magnet-driven EMSG switch confirms the top position.
Clamp sheet-metal jigs in a welding cell; 94 N of practical holding force at 0.5 MPa suits thin-gauge work without crushing.
A 16 mm bore pushes 100 N at 0.5 MPa - fine for gates and flags, light for clamping; a 25 mm bore reaches 245 N when 157 N runs out of muscle. Nothing in this cylinder grips the rod between strokes: centre the valve or drop pressure and it drifts, so add a rod lock or check valve where a load must wait in place. The 165 mm stroke is within standard range, but guide the load externally on long pushes so the 8 mm rod never sees side load.
Quick checklist
Push 157 N and pull 132 N at 0.5 MPa, rising to 220 N push and 185 N pull at 0.7 MPa, with a 32 kgf theoretical maximum at 1.0 MPa. It operates on 0.15-1.0 MPa (22-145 psi), cycles at 30-800 mm/s, breathes through 1/8" ports and carries an M8x1.25 rod thread.
Yes - the magnet is installed as standard in every MAC20X165SU piston, so CMSG, DMSG or EMSG switches mount on the barrel at any time without modifying the cylinder.
