Airtac MAC Stainless Steel Mini Air Cylinder MAC50X230SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X230SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 230mm 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 MAC50X230SU
Rated to push 981.3 N (roughly 100 kgf) at 0.5 MPa and 1373.8 N at 0.7 MPa, the 230 mm stroke on this MAC covers travels that most round minis cannot reach in the same footprint. Air moves the rod in both directions, and needle-adjustable air cushions at each end let you soften the stop progressively - back the screws off fully on first run, then close them gradually.
The 50 mm bore's working envelope sits between a 32 mm unit (402.2 N at 0.5 MPa) and a 63 mm unit (1557.9 N), which makes it the natural pick once a job outgrows mid-size minis. The riveted stainless barrel and 20 um hard-chrome rod handle damp, dusty or washdown-adjacent air, and the piston magnet is standard, so CMSG, DMSG or EMSG switches mount without a special order. In practice, budget about 590 N of push for real work at 0.5 MPa - enough to lift a 50 kg load vertically once you keep 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 (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 MAC50X230SU Is Used
Plating tank lifter
Lifting a basket rack 230 mm out of an electroplating tank, where humid corrosive vapours make the stainless barrel worthwhile.
Bakery plate press
Lowering a dough-press plate with the cushion set soft so pastry layers are not crushed at bottom dead centre.
Palletizer layer clamp
Clamping a layer of sacks on a low-rise palletizer, with an EMSG switch signalling the clamp is fully closed.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X230SU the Right Cylinder?
Size down to a 40 mm bore (628.3 N push at 0.5 MPa) when force demand is light, or up to the 63 mm bore (1557.9 N) for heavier forming and lifting. The flat U back cover bolts straight to fixed plates; add an FA flange for face mounting or an SDB bracket for a pivot. Keep rod speed between 30-800 mm/s and support any side load externally over this 230 mm travel to protect the 16 mm chrome rod. If the application must hold a position with air off, the MAC alone will drift - spec a rod lock or pilot check valve alongside it.
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 MAC50X230SU FAQ
Push 981.3 N and pull 880.8 N at 0.5 MPa; push 1373.8 N and pull 1233.1 N at 0.7 MPa; 200.1 kgf theoretical maximum at 1.0 MPa. The bore is 50 mm, rod 16 mm threaded M14x1.5, ports 1/4 in, operating pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), and the 230 mm stroke runs at 30-800 mm/s.
Both stroke ends have a variable cushion adjusted by needle screws. On commissioning, open the needles fully, run the cylinder at low speed, then close them a little at a time until the 230 mm stroke decelerates smoothly without rebound. The cushion only softens end-of-stroke shock - it never locks the piston, so use a rod lock or check valve if the load must be held when air fails.
