Airtac MAC Stainless Steel Mini Air Cylinder MAC32X470SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X470SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 470mm 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 MAC32X470SU
A flat-end U back cover gives the MAC32X470SU a clean bolt-on face for fixed plates and clamps, while the round stainless barrel and hard-chrome 12 mm rod stand up to washdown and mild corrosion better than painted minis. Double acting with 402.2 N of push and 345.6 N of pull at 0.5 MPa over a 470 mm stroke.
Both ends carry a variable air cushion, so heavier or faster loads can be decelerated pneumatically instead of hammering the aluminium covers. Working at 0.7 MPa lifts push to 563.0 N. In practice plan on about 241 N of usable force at 0.5 MPa - enough to hold or index roughly 24 kg against friction - and the built-in magnet pairs straight onto CMSG or DMSG switches.

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 MAC32X470SU Is Used
Washdown fixture clamp
Clamps stainless trays on a dairy filling line where daily hose-down would rust a painted body; 345.6 N of pull retracts the clamp clear of the tray edge.
Bottling-line stopper gate
A flat back plate bolts the cylinder to the guide-rail frame and the 470 mm stroke drops a stopper blade into the lane ahead of the labeler.
Carton chute diverter
Switches parcels between two gravity chutes with 402 N of push at 0.5 MPa, no linkage needed thanks to the direct flat-end mount.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X470SU the Right Cylinder?
Against its neighbours at 0.5 MPa push: bore 25 offers 245.3 N, bore 32 (this model) 402.2 N, bore 40 reaches 628.3 N. Choose the 40 if your cycle demands continuous force above the low-240s in newtons. Note that a double-acting MAC releases its load the moment supply drops - it parks wherever air leaves it, so add a rod lock or check valve for fail-safe holding.
The U flat-end cover bolts directly to machine plates; LB foot or FA flange mounts bolt on when the frame needs them. Porting is 1/8" on both covers. With 470 mm of travel, keep external side loads off the rod or fit a guide rail beside it - long thin rods bend before they break.
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 MAC32X470SU FAQ
Push 402.2 N and pull 345.6 N at 0.5 MPa; push 563.0 N and pull 483.8 N at 0.7 MPa; 82 kgf theoretical maximum at 1.0 MPa. Stroke is 470 mm double acting, speed 30-800 mm/s, pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi).
No. Being double acting, air pressure is the only thing driving and holding the rod, so a supply cut lets the piston drift with the load. For a held position, fit a pilot check valve on the ports or move to a rod-lock version.
