Airtac MAC Stainless Steel Mini Air Cylinder MAC20X600SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X600SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 600mm 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.

About the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X600SU
With 600 mm of travel in a 20 mm bore, the MAC20X600SU covers long pushes most round minis cannot, built to order since the standard stroke for this bore stops at 500 mm. Double-acting by design, air both extends and retracts the rod, and the variable air cushion at each end can be tuned to kill end-of-stroke bang. The 157 N push and 131.9 N pull at 0.5 MPa translate to around 94 N of realistic working force, enough to shift about 8 kg vertically with a 2:1 safety factor.
Its edge in dirty or wet spots comes from the build: a stainless round barrel rolled tight against aluminium covers, with a hard-chrome plated carbon-steel rod that laughs at splash and humidity. The U flat-end back cover suits fixed, flush bolting, and the piston magnet comes fitted on every unit, so CMSG / DMSG / EMSG switches mount without special orders.

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.
Theoretical Output Force (Ø20mm)
| 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.

Where the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X600SU Is Used
Magazine lift on a PCB line
Raising an electronics magazine of roughly 8 kg through a station, using the 600 mm stroke with external guide posts carrying the side load.
Tote pusher on a roller lane
Shoving loaded totes onto a side lane in a distribution centre, where 157 N at 0.5 MPa handles the rolling resistance and the cushion cushions the arrival.
Web tension arm on a label press
Loading a tension roller across a wide web, with the flat-end U cover bolted to the press frame and a DMSG switch confirming arm position.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X600SU the Right Cylinder?
Compare before you commit: bore 16 offers 100.5 N at 0.5 MPa and bore 25 offers 245.3 N, so this 157 N bore is the middle path for moderate loads on long travel. Note that a standard MAC holds nothing when air is removed; the piston coasts or sinks under load, so pair it with a rod lock or check valve if the load must stay put. Order the 600 mm stroke knowing it is non-standard, and guide the load externally on travels this long so the 8 mm rod never sees side load. The U flat-end cover bolts direct to fixed surfaces; add FA, LB or SDB brackets when the layout demands it.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) is standard for sensors
- ✓ Back cover (CA/U/CM) & mount (FA/LB/SDB)
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 On first run, back off the cushion screws and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MAC Stainless Steel Mini Air Cylinder MAC20X600SU FAQ
Push 157 N and pull 131.9 N at 0.5 MPa; push 219.8 N and pull 184.7 N at 0.7 MPa; theoretical peak 32 kgf at 1.0 MPa. It runs on 0.15-1.0 MPa (22-145 psi) filtered air at 30-800 mm/s, takes 1/8" ports, uses an 8 mm rod with M8x1.25 thread, and the 600 mm stroke is made to order.
The stainless barrel plus 20 um hard-chrome plated rod resist corrosion from washdown, condensation and outdoor exposure, places where painted or bare-aluminium bodies pit and seize. The rolled, riveted construction keeps everything sealed without tie-rods, and the built-in magnet makes switch feedback a plug-on affair.
