Airtac MAC Stainless Steel Mini Air Cylinder MAC32X220SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X220SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 220mm 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 MAC32X220SU
The 32 mm bore of the MAC32X220SU develops 402 N of push and 346 N of pull at 0.5 MPa (563 N and 484 N at 0.7 MPa, 82 kgf theoretical maximum), double acting with a variable air cushion at each end to absorb stroke shock. The SU code pairs the standard body with a flat-end U back cover, so fixed brackets bolt straight on without adapters.
Its riveted stainless round barrel and hard-chrome plated 20 um rod shrug off washdown and damp shop air far better than painted minis, and because the magnet is built in as standard, CMSG / DMSG / EMSG switches clip on without special ordering. Run it 30-800 mm/s on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um; sizing at 60% of rating leaves roughly 241 N of honest working force for the real job.

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 MAC32X220SU Is Used
Carton ejector
Ejects sealed cartons off a packaging conveyor across 220 mm of travel, with 402 N of push handling stacked loads at 0.5 MPa.
Fixture clamp arm
Clamps aluminium extrusions in a CNC fixture; 346 N of pull retracts the arm clear of the cutting path each cycle.
Hopper slide gate
Opens and closes a stainless hopper slide gate in a food plant, where the washdown-friendly barrel earns its keep.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X220SU the Right Cylinder?
If 402 N at 0.5 MPa is more than the job needs, the 25 mm bore MAC delivers 245 N for lighter clamps; when the load climbs toward 600 N, step up to the 40 mm bore with 628 N. Note that a plain MAC drifts when air is removed - the cushion slows the ends but holds nothing - so pilot a check valve or add a rod lock if the 220 mm stroke must park under load.
The SU flat-end cover plus FA flange or LB foot brackets cover fixed frames, and the standard magnet suits CMSG sensing anywhere along the full travel.
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 MAC32X220SU FAQ
Push 402 N and pull 346 N at 0.5 MPa supply, rising to 563 N and 484 N at 0.7 MPa, with 82 kgf as the theoretical ceiling. Supply air is filtered to 40 um within 0.15-1.0 MPa (22-145 psi).
No - every MAC cylinder carries a built-in magnet as standard, so CMSG, DMSG or EMSG switches clip onto the stainless barrel and sense position without a special piston.
