Airtac MAC Stainless Steel Mini Air Cylinder MAC40X30SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X30SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 30mm 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 MAC40X30SCM
The MAC40X30SCM pairs a 40 mm bore and 30 mm stroke with a CM round-end back cover, so the body sits flush where frame space is tight. Double-acting throughout, it pushes 628 N at 0.5 MPa and dials end-of-stroke shock down with the variable air cushion at both ends.
Its rolled stainless tube and hard-chrome 16 mm rod resist mild corrosion in humid plants and outdoor enclosures. Sized with margin, expect about 377 N of dependable push at 0.5 MPa - around a 32 kg vertical lift when you halve the rating for 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 MAC40X30SCM Is Used
Rising stopper pin on an electronics tray conveyor
The 30 mm stroke pops a stopper between tray lanes; the cushioned ends let the pin cycle at high line speed without rattling the guide bush.
Hold-down clamp on an aluminium trim jig
Around 377 N of working push clamps extrusions against the fence before the saw cycles, and the stainless barrel copes with coolant mist.
Chute door latch on tote pick modules
The round-end cover bolts flush inside chute framing to throw a latch bolt 30 mm; the magnet feeds a DMSG switch to confirm the locked state.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X30SCM the Right Cylinder?
If 628 N at 0.5 MPa overshoots the job, the 25 mm MAC25 gives 245 N for less; the 50 mm MAC50 at 981 N covers loads beyond about 590 N. Air supply runs 0.15-1.0 MPa (22-145 psi). Note that nothing locks the rod when air drops - a centred valve lets the load coast, so fit a pilot check valve where position must hold. The round-end cover takes FA flange, LB foot or SDB pivot brackets, and the standard magnet pairs with CMSG, DMSG or EMSG switches.
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 MAC40X30SCM FAQ
Push is 628 N and pull 528 N at 0.5 MPa. At 0.7 MPa push reaches 880 N. Theoretical peak is 128 kgf at 1.0 MPa. It is double acting with a variable air cushion, runs at 30-800 mm/s, uses 1/8" ports and an M12x1.25 rod thread.
The rolled stainless tube plus hard-chrome plated rod stand up to humidity, coolant mist and occasional rinsing, where painted mini cylinders flake and jam. Pressure range is 0.15-1.0 MPa (22-145 psi) with proof pressure of 1.5 MPa (215 psi).
