Airtac MAC Stainless Steel Mini Air Cylinder MAC40X500SUFA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X500SUFA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 500mm 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 MAC40X500SUFA
Bolting flush to a machine wall through its FA flange, this long-stroke 40 mm cylinder holds 628 N of extend force and 528 N of return force at 0.5 MPa. Air works in both directions, and variable cushions at each end trim the stop impact no matter where in the 30-800 mm/s range you run.
A rolled stainless barrel over a 20 um hard-chrome rod stands up to coolant mist and periodic hose-down that pit painted mini bodies. Because the magnet is included as standard, CMSG / DMSG / EMSG switches drop on for position feedback with no special piston order. In practice keep continuous work near 377 N at 0.5 MPa - about 32 kg hoisted vertically on 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
| Max (@1.0 MPa) | 128 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 MAC40X500SUFA Is Used
AGV lift finger
Extending a lift finger under pallet skids on an automated guided vehicle, the flange mounting flat against the chassis frame.
CNC door closer
Swinging full-height CNC enclosure doors, with the cushions damping the latch so the sheet-metal panels stay tight.
Web tension dancer
Loading a dancer arm on a film converting line at a controlled 377 N band, the 500 mm stroke absorbing web speed changes.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X500SUFA the Right Cylinder?
Scale from the 20 mm bore (157 N at 0.5 MPa) up through this 40 mm (628 N) to the 50 mm bore (981 N) as the payload demands. Do not rely on the cylinder to park a load: with no air the piston slides, so fit a rod lock or pilot check valve for load-holding duty. The FA flange fixes the body rigidly, which suits horizontal pushes where foot or pivot mounts would let the barrel rock. Given 500 mm of unsupported 16 mm rod, brace long tooling externally and check that the 1/8 inch port face clears the flange bolts during installation.
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 MAC40X500SUFA FAQ
At 0.5 MPa: 628.3 N extend, 527.8 N retract. At 0.7 MPa: 879.6 N extend, 738.9 N retract. Peak theoretical output is 128.1 kgf at 1.0 MPa. Run it on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um.
The flange bolts the cylinder body rigidly to a machine face, preventing the barrel from rocking on long 500 mm pushes. Everything else stays standard - 1/8 inch PT ports, 30-800 mm/s speed, and the factory-fitted magnet for CMSG, DMSG and EMSG switches.
