Airtac MAC Stainless Steel Mini Air Cylinder MAC50X350SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X350SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 350mm stroke, 1/4" 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 MAC50X350SU
A flat U-shaped back cover lets the MAC50X350SU bolt straight against a machine face, with 350 mm of powered stroke behind it. At 0.5 MPa the 50 mm bore extends with 981.3 N and retracts with 880.8 N; raise supply to 0.7 MPa and extend force climbs to 1373.8 N, while theoretical output tops out at 200.1 kgf at 1.0 MPa. Both directions are air driven, and the variable cushion at each end trims the landing.
Hard-chrome plate on the carbon-steel rod plus the stainless rolled barrel shrug off coolant mist and outdoor damp that would flake paint off ordinary minis. Cushion needles at both heads soften landings, so faster cycles or heavier jigs stay safe at up to 800 mm/s. Plan around 589 N of dependable thrust at 0.5 MPa - roughly a 50 kg vertical lift kept to a 2:1 margin - and the stock magnet accepts CMSG, DMSG or EMSG switches anywhere on the tube.

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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 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 MAC50X350SU Is Used
Cold-room tray ejector
Ejects stacked trays from a chill-room conveyor; the stainless body and chrome rod laugh at the condensation that rusts painted minis.
Greenhouse vent pusher
Opens ridge vents on glasshouses; 981 N at 0.5 MPa moves stiff frames and the barrel withstands year-round outdoor damp.
Loom cloth doffer
Pushes finished cloth rolls off the loom rail; cushioned ends protect delicate fabric at both extremes of the 350 mm travel.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X350SU the Right Cylinder?
Compare force classes before committing: the 40 mm bore manages 628.3 N push at 0.5 MPa and the 63 mm bore 1557.9 N, so 50 mm sits mid-pack with 981.3 N. Nothing locks the rod mid-stroke - exhaust the valve and an unbalanced load will creep it, which a rod lock or pilot check valve prevents. The U back cover pairs with LB foot or FA flange mounts and SDB pivot brackets, and I or Y knuckles adapt the rod end to linkages. A 350 mm rod with nothing around it bends under sideways force, so run the load in linear guides or fit a stop block.
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 MAC50X350SU FAQ
Extend 981.3 N and retract 880.8 N at 0.5 MPa; extend 1373.8 N at 0.7 MPa; 200.1 kgf theoretical maximum at 1.0 MPa. Operating window is 0.15-1.0 MPa (22-145 psi), rod speed 30-800 mm/s, bore 50 mm, stroke 350 mm, port 1/4 in PT.
Needle screws at each end meter the air exhausting through the cushion chamber. Back them off on first run-up, then close gradually until the load lands softly - this lets you run faster or carry more weight without hammering the covers at the end of the 350 mm stroke.
