Airtac MAC Stainless Steel Mini Air Cylinder MAC32X330SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X330SU 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 MAC32X330SU
The MAC32X330SU is a 32 mm bore double acting mini cylinder: air drives the rod both ways, and a variable air cushion at each end soaks up end-of-stroke shock so a 330 mm travel can run at speed without hammering the covers. At 0.5 MPa it pushes 402 N and pulls 346 N.
A riveted stainless round barrel with a hard-chrome plated 12 mm rod shrugs off washdown and damp plant air far better than painted minis, and the piston ships with a built-in magnet so CMSG, DMSG or EMSG switches drop straight on. Worked out with a real-world margin, that rating leaves about 240 N of dependable push at 0.5 MPa.

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 MAC32X330SU Is Used
Brewery rinse gate
Slides a spray hood across a CIP rinse lane; the stainless barrel shrugs off daily hose-down and 240 N of working push is ample for a lightweight gate.
Carton lane diverter
Nudges cartons between sorting lanes with 330 mm of reach, and the two-way cushion stops the pusher without slamming the frame.
Fixture lift on a machining bench
Raises a 20 kg inspection nest vertically with a 2:1 margin, matching the real weight of the pallet and part.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X330SU the Right Cylinder?
Compare both ways: the 25 mm bore of this family pushes 245 N at 0.5 MPa, and the 40 mm bore reaches 628 N, so 32 mm sits squarely in the middle for 330 mm slides. Ports are 1/8 inch on all 20-40 mm bores and the rod thread is M10x1.25. When the valve centres or air drops the rod floats - it will not hold a position alone, so add a pilot check valve or rod lock where the load must stay parked. The U flat-end back cover suits direct bolting, with FA flange, LB foot or SDB pivot brackets available, and at this exposed 330 mm stroke, guide the load or fit an I or Y knuckle so side forces never bend 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 MAC32X330SU FAQ
At 0.5 MPa it pushes 402 N and pulls 346 N; at 0.7 MPa push rises to 563 N, and the theoretical maximum is 82 kgf at 1.0 MPa. It runs on 0.15-1.0 MPa (22-145 psi), takes 1.5 MPa (215 psi) proof, moves at 30-800 mm/s and cushions at both ends.
Back both cushion needle screws fully off, run the cylinder slowly through its 330 mm stroke, then close each screw gradually until end-of-stroke impact disappears. The cushion is variable, so you can re-tune it any time the load or speed changes.
