Airtac MAC Stainless Steel Mini Air Cylinder MAC63X325SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X325SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 325mm stroke, 1/4" 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 MAC63X325SCA
Long travel plus top-of-range muscle: the MAC63X325SCA sweeps 325 mm while pushing 1557.9 N at 0.5 MPa (1457.4 N on retract), and 2181.0 N at 0.7 MPa, double acting with a variable air cushion at both stroke ends.
Its rolling-packed stainless barrel and 20 um hard-chrome rod stand up to wet, outdoor and washdown cells that quickly ruin painted mini cylinders. For sizing, count on roughly 935 N of honest working push at 0.5 MPa - enough to raise about 79 kg vertically with a 2:1 margin. Supply air at 0.15-1.0 MPa (22-145 psi) and run 30-800 mm/s; the built-in magnet drives CMSG, DMSG or EMSG switches straight from stock.

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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1458 N |
| 0.7 MPa | 2182 N | 2041 N |
| Max (@1.0 MPa) | 318 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 MAC63X325SCA Is Used
Carton ejector, case packer
Knocks filled cartons off a cross conveyor with 935 N of working force at 0.5 MPa and a cushioned stop both ways.
Idler-arm belt tensioner
Keeps steady tension on a wide conveyor belt through a pivoting idler hung from the CA cover.
Cold-store slide gate
Pushes a heavy sliding gate fully open in one 325 mm travel; the stainless barrel shrugs off condensation in chill rooms.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X325SCA the Right Cylinder?
If 981.3 N push at 0.5 MPa from a 50 mm bore covers the load, take the smaller cylinder and save air; when it does not, this 63 mm bore is the ceiling of the range. A 325 mm rod amplifies side loads, so guide the payload in external linear bearings and keep the travel square, or seal life suffers. The CA pivot cover suits swinging linkages - pair it with an SDB pivot bracket and I or Y rod knuckles for a full articulating chain. Air dumped mid-cycle leaves the piston free to drift, so a rod lock or pilot check valve is the answer wherever a position must be held.
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 MAC63X325SCA FAQ
Push at 0.5 MPa is 1557.9 N and pull 1457.4 N; at 0.7 MPa push rises to 2181.0 N and pull to 2040.3 N. Theoretical peak is 317.7 kgf at 1.0 MPa. Plan real work around 935 N and the cylinder will last.
Guide the load externally - long rods bend under side loads. Back the cushion screws off before first run and close them gradually to a soft stop. The standard-fit magnet means CMSG / DMSG / EMSG switches clip onto the barrel for end-of-stroke signals.
