Airtac MAC Stainless Steel Mini Air Cylinder MAC32X300SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X300SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 300mm 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 MAC32X300SU
Feed it 0.5 MPa and the 32 mm piston throws 402.2 N forward and 345.6 N back; raise the pressure to 0.7 MPa and those figures climb to 563.0 N and 483.8 N. Both ends carry an adjustable air cushion, so this 300 mm stroke can run at the top of the 30-800 mm/s range without slamming the covers.
The barrel is stainless steel with covers rolled in place - a riveted round body rather than a bolted stack - so splashes, humidity and outdoor exposure bother it far less than painted minis. The 12 mm rod is hard-chrome plated carbon steel. It runs on filtered air at 0.15-1.0 MPa (22-145 psi). For planning, count on about 241 N of honest working push at 0.5 MPa, close to a 20 kg vertical lift with margin, and the built-in magnet pairs with CMSG, DMSG or EMSG switches as standard.

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 MAC32X300SU Is Used
Die ejection on a small press
563 N at 0.7 MPa pushes finished parts clear of the die face, with the exhaust cushion keeping the kick gentle.
Lid clamping before a leak test
Roughly 241 N of working force presses a housing lid onto its gasket for the duration of the test cycle.
Rinse-nozzle travel over a wash tank
The stainless barrel and chrome rod shrug off daily washdown while the 300 mm sweep covers the full tank width.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X300SU the Right Cylinder?
Boundaries are easy: a 25 mm bore tops out at 245.3 N at 0.5 MPa and a 40 mm bore starts at 628.3 N, so pick 32 mm when the load sits between. Because the cylinder is double acting with no internal lock, a centred valve lets the rod drift - fit a rod lock or pilot check valve where holding matters.
The U back cover gives a flat end face for direct fixing; FA flange, LB foot and SDB pivot brackets bolt on when needed. Over 300 mm of travel, keep the thrust in line with the rod or guide the load externally.
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 MAC32X300SU FAQ
Expect 402.2 N push and 345.6 N pull at 0.5 MPa, 563.0 N push and 483.8 N pull at 0.7 MPa, and a theoretical 82 kgf maximum at 1.0 MPa. Ports are 1/8", the rod thread is M10x1.25, rod diameter 12 mm, stroke 300 mm.
Back both needle screws off before the first strokes, then close them gradually until the load stops just short of the covers. The cushion is variable, not fixed, so you can retune it whenever speed or load changes within the 30-800 mm/s envelope.
