Airtac MAC Stainless Steel Mini Air Cylinder MAC32X325SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X325SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 325mm 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 MAC32X325SCA
Around 400 newtons of push is the working zone of this cylinder: the MAC32X325SCA delivers 402.2 N at 0.5 MPa and 563.0 N at 0.7 MPa over a 325 mm stroke, double acting with a variable air cushion at each end. Halving the 41 kg thrust equivalent gives a sensible vertical lift target of about 20 kg, a quick way to match real part weights.
Construction is AirTAC's riveted round body - a stainless barrel rolled onto aluminium covers with a stainless block - so the shell stays sealed and rigid without fasteners to retorque. The 12 mm hard-chrome rod keeps its finish through damp plant air, and the standard magnet means position feedback with CMSG, DMSG or EMSG switches is a snap-on job, never a special-order piston.

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 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 MAC32X325SCA Is Used
Case packer push-off
The 325 mm stroke sweeps a full layer of cartons onto the pack table; 402.2 N at 0.5 MPa is ample for a 20 kg layer.
Sluice gate on a dyeing machine
Damp dye-house air is no problem for the stainless barrel, and the cushions settle the heavy gate without a metal clunk.
Lift-and-lower parts elevator
With about 20 kg of vertical lift capability at a 2:1 margin, it hoists trays between bench and shelf levels; the magnet confirms top-of-stroke.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X325SCA the Right Cylinder?
For lighter duty a 25 mm bore gives 245.3 N push at 0.5 MPa; for heavy clamping a 40 mm bore lifts that to 628.3 N. If the load must stay put with the valve centred, note that a plain MAC cylinder coasts to whatever position air leaves it - add a rod lock or pilot check valve for positive holding. The CA pivot cover suits swing links and the SDB bracket suits trunnion-style mounts; FA flange and LB foot cover fixed installations. At 325 mm of travel, guide the load externally so bending moment never reaches the 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 MAC32X325SCA FAQ
Push is 402.2 N and pull 345.6 N at 0.5 MPa; at 0.7 MPa push is 563.0 N and pull 483.8 N, peaking at a theoretical 82 kgf at 1.0 MPa. Ports are 1/8", rod thread M10x1.25 on a 12 mm rod, operating pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), and cushioning is adjustable at both ends.
The stainless barrel is rolled onto the aluminium covers, forming a sealed joint with no separate fasteners to loosen. That construction plus the hard-chrome rod tolerates washdown splashes and humid air far better than painted minis, keeping maintenance intervals long.
