Airtac MAC Stainless Steel Mini Air Cylinder MAC32X440SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X440SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 440mm 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 MAC32X440SU
Built as a round-body mini cylinder with a riveted stainless-steel barrel, the MAC32X440SU runs double acting with a variable air cushion at both ends. At 0.5 MPa it pushes 402.2 N and pulls 345.6 N, rising to 563.0 N and 483.8 N at 0.7 MPa - up to 82 kgf theoretical at 1.0 MPa. The 12 mm hard-chrome plated rod shrugs off splash and humidity that quickly ruin painted-steel minis.
For real work, budget about 241 N - roughly 60% of the 0.5 MPa push - which is around 20 kg lifted vertically with a 2:1 margin. The U flat-end back cover bolts straight to a fixed plate without extra brackets, and the built-in magnet picks up CMSG / DMSG / EMSG switches as standard kit. Ports are 1/8" with an M10x1.25 rod thread; pressure span is 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 MAC32X440SU Is Used
Carton push-off
Kicking sealed cartons off a 400 mm packing conveyor: 402 N at 0.5 MPa clears a loaded tray, and the end cushion stops the load bouncing at the stop.
Pail lift post
Raising 15 kg paint pails on a filling-line lift post - about 20 kg of vertical capacity keeps a comfortable margin, with a CMSG switch confirming top position.
Washdown gate
A rinse-zone diverter gate on a dairy line where painted bodies corrode fast; the stainless barrel and chrome rod survive daily hose-down across 440 mm travel.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X440SU the Right Cylinder?
A 25 mm bore covers jobs under about 245 N at 0.5 MPa; once you need more than roughly 628 N, move to the 40 mm MAC. With 440 mm of stroke, support and guide the load externally so side forces never bend the 12 mm rod. Remember the piston drifts the moment air drops or the valve centres - a rod lock or pilot check valve holds it. LB foot, FA flange and I / Y rod knuckles all bolt on.
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 MAC32X440SU FAQ
Push is 402.2 N and pull 345.6 N at 0.5 MPa; at 0.7 MPa these become 563.0 N and 483.8 N, with a theoretical maximum of 82 kgf at 1.0 MPa. Run it on 40 um filtered air at 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), rod speed 30-800 mm/s, 1/8" ports, M10x1.25 rod thread.
The barrel is a rolled stainless tube and the rod carries 20 um of hard chrome, so humidity, splash and mild detergents do not pit or flake as they would on painted mini cylinders. Aluminium covers are rolled onto the tube, keeping the joint sealed through repeated cleaning cycles.
