Airtac MAC Stainless Steel Mini Air Cylinder MAC40X350SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X350SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 350mm 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 MAC40X350SCM
Long travel with muscle: this 40 mm bore MAC pushes 628.3 N and pulls 527.8 N at 0.5 MPa, rising to 879.6 N when you feed it 0.7 MPa. Air drives the rod out and back, and needle-adjustable cushions at each end soak up the momentum of 350 mm travel. The CM round-end back cover bolts flush to a fixed face without an adapter plate, and the piston magnet ships standard for CMSG or EMSG sensing.
A riveted stainless barrel, aluminium-alloy covers and a 20 um hard-chrome rod give the body its corrosion edge in damp plants. Run it 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s. For sizing, count on near 377 N of honest working force at 0.5 MPa - the design figure most machine builders apply - or about 32 kg of vertical lift at half 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 MAC40X350SCM Is Used
Fixture clamp on appliance assembly
Clamps washer door panels at the weld cell with 628 N hold force at 0.5 MPa and a magnet-sensed confirm signal.
Carton ejector at a case packer
Rejects leaning cartons on the outfeed; the air cushion stops the 350 mm ram without slamming the end stop.
Riser platform on a lab feeder
Raises sample trays of up to roughly 32 kg vertically between stations, with switch feedback at both ends.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X350SCM the Right Cylinder?
A 32 mm bore would save air but cap you at 402 N push; a 50 mm bore reaches 981 N but costs more. The 40 mm sits between with 628 N and a 16 mm rod. If the valve centres mid-cycle the rod coasts freely - cushions stop shock, they do not park the load - so a pilot check valve or rod lock belongs on any held station. Mount the CM end flat, add an FA flange or SDB bracket if the frame needs one, and brace long strokes against side load.
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 MAC40X350SCM FAQ
Push is 628.3 N and pull 527.8 N at 0.5 MPa; at 0.7 MPa expect 879.6 N push and 738.9 N pull. The theoretical maximum at 1.0 MPa is 128.1 kgf. Port size is 1/8", rod thread M12x1.25, rod 16 mm, stroke 350 mm.
No. Every MAC40X350SCM ships with the piston magnet built in as standard, so CMSG, DMSG or EMSG switches clip onto the barrel and read position immediately - no special-order piston required.
