Airtac MAC Stainless Steel Mini Air Cylinder MAC32X350SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X350SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 350mm 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 MAC32X350SU
With a 350 mm stroke on a 32 mm bore, this MAC pushes 402 N (about 41 kgf) at 0.5 MPa and pulls 345.6 N, both directions air-powered, with a variable cushion at each end soaking up the stops. The riveted stainless barrel and hard-chromed 12 mm rod shake off washdown and damp plant air, an edge painted mini cylinders lose fast. Double-acting means air retracts as well as extends - there is no spring return.
Plan real work at roughly 241 N, six tenths of the 402 N rating, or read it as vertical lift of about 41 kg at the rod, 20 kg with a two-to-one margin. The U flat-end back cover bolts straight to fixed faces without a bracket, and the built-in magnet takes CMSG, DMSG or EMSG switches out of the box. Speed range is 30-800 mm/s across 0.15-1.0 MPa (22-145 psi).

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 MAC32X350SU Is Used
Bottle line pusher
Rows of PET bottles clearing a filler conveyor need a long reach; the 350 mm stroke sweeps them onto the reject lane with 402 N behind it, and the end cushions stop the pusher head without a bang.
Welding fixture lift
A 20 kg clamp fixture rises vertically well inside the two-to-one margin of the 41 kg lift equivalent, and the stainless barrel tolerates the spatter and grinding dust around weld cells.
Washdown gate actuator
Sliding access gates on a dairy filling line cycle all shift; the rolled stainless body and chrome rod shrug off the daily hose-down that peels coated minis.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X350SU the Right Cylinder?
A 25 mm bore delivers 245 N at 0.5 MPa if the load is lighter; step up to a 40 mm bore (628 N) when force margin matters. At 350 mm the rod is long, so guide the load and keep side force low to protect the 12 mm rod; an LB foot or FA flange stiffens the install, and the U flat-end cover suits direct face fixing. When the valve centres or air drops, the rod drifts freely - add a pilot check valve or a rod lock if the slide must stay put.
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 MAC32X350SU FAQ
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N; at 0.7 MPa those rise to 563 N and 483.8 N, with 82 kgf as the theoretical maximum at 1.0 MPa. Air ports are 1/8", the rod is 12 mm with an M10x1.25 male thread, and the standard stroke ceiling for this bore is 500 mm.
Both ends carry a variable air cushion with its own needle screw. On first run, back the needles fully open, cycle gently, then close them gradually until the end-of-stroke knock disappears. Keep speed within 30-800 mm/s. The cushion slows only the last few millimetres - it is not a brake.
