Airtac MAC Stainless Steel Mini Air Cylinder MAC32X145SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X145SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 145mm 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 MAC32X145SU
Built on a riveted stainless-steel barrel with aluminium covers, the MAC32X145SU shrugs off moisture and mild washdown far better than painted-steel minis, and its 12 mm hard-chrome plated rod keeps sliding friction low over the 145 mm travel. Double acting with a variable air cushion at both ends, this 32 mm bore pushes 402 N and pulls 346 N at 0.5 MPa, and the cushion lets you bleed off end-of-stroke shock when cycling fast.
Because the piston magnet ships as standard, CMSG, DMSG or EMSG switches clip straight onto the barrel - no special-order piston needed. Working at 0.5 MPa, budget around 241 N for real work rather than the full 402 N rating, which means this cylinder lifts about 20 kg vertically with a 2:1 margin.

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 MAC32X145SU Is Used
CNC Fixture Clamping
Clamps aluminium housings in a machining jig; about 241 N of usable force at 0.5 MPa holds parts through light milling cuts.
Packaging Push-Off
Ejects cartons sideways off a packaging conveyor; the twin air cushions protect the covers during fast cycling up to 800 mm/s.
Small Part Lifting
Raises machined lids and jigs; about 20 kg vertical lift with a 2:1 margin across the full 145 mm stroke.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X145SU the Right Cylinder?
Compare forces at 0.5 MPa: the smaller 25 mm bore delivers 245 N, while stepping up to a 40 mm bore gets 628 N - the 32 mm at 402 N sits squarely between. Note that a plain MAC cylinder drifts if air is cut, so fit a rod lock or pilot check valve when the load must stay put. The U flat-end back cover suits fixed mounting with LB foot or FA flange brackets; 1/8 inch PT ports and an M10x1.25 rod thread come standard, and the built-in magnet is ready for CMSG or DMSG switch sensing.
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 MAC32X145SU FAQ
At 0.5 MPa it pushes 402 N and pulls 346 N; at 0.7 MPa push rises to 563 N, and the theoretical maximum for a 32 mm bore is 82 kgf at 1.0 MPa. Working pressure spans 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure.
Yes - the riveted stainless-steel barrel and 20 um hard-chrome plated rod stand up to humidity and mild washdown. Speed range is 30-800 mm/s, and the variable cushion needle screws at both ends should be opened gradually on first run.
