Airtac MAC Stainless Steel Mini Air Cylinder MAC32X330SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X330SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 330mm 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 MAC32X330SCA
At 330 mm of stroke the MAC32X330SCA reaches across wide gates and sliding doors while keeping the 32 mm bore's 402.2 N push at 0.5 MPa - enough, with margin, to hoist roughly 20 kg vertically or deliver 241 N of real working force horizontally. At 0.7 MPa the same bore delivers 563.0 N for stubborn loads.
AirTAC builds this range by rolling the stainless barrel, aluminium covers and a stainless block into one riveted unit that fits narrow machine gaps and shrugs off the splash zones common in food plants. The variable air cushion at both ends lets you run the full 800 mm/s on light loads and still land soft, and the built-in magnet feeds CMSG, DMSG or EMSG switches for end-of-travel confirmation.

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 MAC32X330SCA Is Used
Charger hood on a battery bay
The pivot mount swings the heavy hood through its arc; about 20 kg of vertical lift capability covers the panel weight with a 2:1 margin.
Diverting pusher on a snack-food line
Washdown splash around the conveyor suits the stainless barrel; cushions let the pusher drive product sideways at 600 mm/s without jolt.
Tilting weld fixture
A CA pivot at the rod end tips a welding jig through 330 mm of travel; the magnet confirms the fixture is fully home before arc start.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X330SCA the Right Cylinder?
One bore down, the 25 mm size of the MA range offers 245.3 N push at 0.5 MPa and suits lighter gates; one bore up, the 40 mm size reaches 628.3 N for heavier doors. This cylinder moves but does not hold: expect drift whenever supply air is lost, and specify a rod lock or pilot check valve where a raised gate must stay up. CA pivot covers plus an SDB bracket give a clean trunnion arrangement, or bolt through the FA flange for a rigid base. On a 330 mm stroke keep the door riding in its own track so side forces never load 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 MAC32X330SCA FAQ
Push 402.2 N and pull 345.6 N at 0.5 MPa; push 563.0 N and pull 483.8 N at 0.7 MPa; theoretical maximum 82 kgf at 1.0 MPa. 12 mm rod with M10x1.25 thread, 1/8" ports, operating pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s, double acting with variable cushions at both ends.
On first commissioning, back both cushion needle screws fully out, then close them gradually until end-of-stroke impact disappears. If the cylinder starts banging later, check for supply pressure loss or worn guide components before touching the needles again.
