Airtac MAC Stainless Steel Mini Air Cylinder MAC40X490SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X490SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 490mm 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 MAC40X490SCA
With 628.3 N of push at 0.5 MPa (879.6 N at 0.7 MPa) and a theoretical 128.1 kgf ceiling, the MAC40X490SCA sits in the mid-force band of the MA family while staying a compact round-body mini. It is double acting with a variable air cushion at both ends, running 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.
Construction is a stainless round barrel with aluminium covers riveted on and a hard-chrome plated carbon-steel rod, so the long 490 mm rod holds up in humid or outdoor air. Derived from the push figure, the raw lift capacity is about 64 kg vertical, or halve it to roughly 32 kg for a 2:1 margin on a real part weight. The CA pivot back cover takes pin-jointed mounts, and the standard magnet pairs with CMSG, DMSG and EMSG 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 (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 MAC40X490SCA Is Used
Grain silo chute gate
Opens and closes a long slide gate on a grain silo discharge chute; 628 N at 0.5 MPa shears through the grain column and the variable cushion damps the gate into its seat.
Cross-belt sorter pusher
Pushes cartons across a cross-belt sorter with 490 mm of travel; keep the pusher arm externally guided so side loads do not bend the long hard-chrome rod.
Machining scrap flap
Dumps swarf and scrap off a machining-cell conveyor into a hopper through a long flap lever; the CA pivot mount tracks the lever arc over the full 490 mm stroke.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X490SCA the Right Cylinder?
For reference, 0.5 MPa push is 402 N on the 32 mm bore and 981 N on the 50 mm bore; this 40 mm model lands between them at 628 N. Do not treat the cushion as a brake - it softens end-of-stroke shock but holds nothing, so use a rod lock or pilot check valve where the load must stay in position. At 490 mm the rod is long, so keep push-pull aligned and guide any off-axis load to protect the rod and seals. The CA pivot back cover suits pin mounts while FA flange and LB foot brackets handle fixed frames; the magnet comes standard on every unit.
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 MAC40X490SCA FAQ
Push at 0.5 MPa is 628.3 N and pull 527.8 N; at 0.7 MPa the figures are 879.6 N push and 738.9 N pull, with a theoretical 128.1 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, port 1/8", rod thread M12x1.25, and the magnet for CMSG / DMSG / EMSG switches is built in as standard.
No. Every MAC cylinder leaves the factory with the magnet fitted, so CMSG, DMSG or EMSG switches simply clip onto the barrel and read end-of-stroke or mid-stroke positions without any special-order piston. The 490 mm stroke here is within the 500 mm standard limit for this bore.
