Airtac MAC Stainless Steel Mini Air Cylinder MAC20X240SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X240SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 240mm 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 MAC20X240SCA
Swinging linkages and pivoting levers are where the MAC20X240SCA earns its keep: a CA pivot back cover on a 240 mm double-acting stroke, with needle-adjustable air cushion at both ends. Push force is 157 N and pull 131.9 N at 0.5 MPa, rising to 219.8 N at 0.7 MPa.
The rolled stainless body and 20 um hard-chrome rod resist condensation and plant washdown, outlasting painted aluminium minis in humid shops. Vertical lift at full theoretical pressure works out near 16 kg; halving that to about 8 kg gives a practical two-to-one margin when you size a counterweighted arm against real part weight.

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 MAC20X240SCA Is Used
Diverter arm
Drives a swing-arm diverter routing parcels between two conveyor lanes; the CA pivot eyes bolt straight to the clevis pin.
Index lever
Snaps a pawl lever into the next indexing position on a rotary assembly table, the 157 N push positively engaging each detent.
Lid lift assist
Raises a hinged machine cover of about 8 kg with margin, the variable cushion catching the last degrees of travel quietly.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X240SCA the Right Cylinder?
Downsize to a 16 mm MAC (100.5 N push at 0.5 MPa) for lighter pushes; a 25 mm bore lifts the ceiling to 245.3 N. Because the piston is free to move when supply drops, add a pilot check valve where a pivoted arm must park under load. SDB pivot brackets and the CA back cover already handle the swing; FA flange or LB foot mounts swap in if the machine layout changes. Keep linkages aligned along the rod axis - long cushioned strokes punish off-axis loading on the 8 mm rod.
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 MAC20X240SCA FAQ
Push is 157 N and pull 131.9 N at 0.5 MPa; at 0.7 MPa the figures become 219.8 N push and 184.7 N pull, peaking at a theoretical 32 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa (22-145 psi) and the fluid is air filtered to 40 um.
The riveted stainless barrel with its hard-chrome 8 mm rod resists condensation, mild chemicals and outdoor humidity that blister painted mini cylinders, so it suits food areas, washdown-adjacent zones and outdoor stations.
