Airtac MAC Stainless Steel Mini Air Cylinder MAC32X20SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X20SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 20mm 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 MAC32X20SU
Compact but forceful, MAC32X20SU pairs the 32 mm bore with a 20 mm stroke and a flat-end U back cover for direct screw-down mounting. Air on both sides makes it double acting, and the variable cushion at each end can be opened gradually until end-of-stroke shock disappears, even at 800 mm/s.
At 0.5 MPa the rod pushes 402 N and pulls 345 N. In practical terms that lifts about 20 kg vertically once the theoretical 41 kg is halved for a 2:1 margin, so match it against the actual weight you move. The stainless round barrel and 20 um hard-chrome rod shrug off washdown, and the standard magnet pairs with CMSG, DMSG and EMSG switches for end-of-stroke signals.

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 MAC32X20SU Is Used
Case clamp on a carton sealer
20 mm of clamping travel with 402 N holds cases square while the flaps are folded and taped.
Small process valve on a rinse manifold
The 20 mm toggle shifts a compact valve stem, and the cushion dials out the slam when it seats.
Tray stop at a conveyor merge
The rod kicks up a stop blade to release one tray at a time, lifting parts of around 20 kg or less vertically.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X20SU the Right Cylinder?
One step down, the 25 mm bore pushes 245 N; one step up, 40 mm gives 628 N at 0.5 MPa - pick by clamp or press force, not by eye. With no air the piston is free to move, so a load that must be held calls for a rod lock or pilot check valve, not a cushion setting. The flat-end cover mounts flush against a plate; FA flange, LB foot and SDB pivot brackets are there if the machine layout changes later.
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 MAC32X20SU FAQ
0.5 MPa gives 402.2 N push and 345.6 N pull; 0.7 MPa gives 563.0 N push and 483.8 N pull; theoretical maximum 82 kgf at 1.0 MPa. Stroke 20 mm, 12 mm rod, M10x1.25 male thread, 1/8 in ports, 0.15-1.0 MPa (22-145 psi) pressure, speed 30-800 mm/s.
No. Every MAC32X20SU ships with the piston magnet already installed as standard, so CMSG, DMSG and EMSG switches mount on the barrel and read extend and retract positions without any special-order piston. The switches signal position only - with air off the piston still moves freely, so add a rod lock or check valve to hold a load.
