Airtac MAC Stainless Steel Mini Air Cylinder MAC50X240SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X240SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 240mm 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 MAC50X240SCA
Where a mechanism swings rather than slides, the CA pivot back cover on this MAC50X240SCA takes the pivot pin directly - no fabricated bracket needed between cylinder and linkage. The 50 mm bore delivers 981.3 N of push at 0.5 MPa (100 kgf equivalent) and 1373.8 N at 0.7 MPa over a 240 mm stroke, double acting, with a variable air cushion at each end to absorb the rotary mechanism's momentum.
Construction is AirTAC's rolled round-body design: a stainless-steel barrel with aluminium covers riveted on, and a carbon-steel rod hard-chrome plated to 20 um for corrosion resistance in outdoor or damp duty. The magnet comes built in, ready for CMSG / DMSG / EMSG switches. For sizing, treat about 590 N (six tenths of the 0.5 MPa rating) as the usable push - that lifts roughly 50 kg 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 MAC50X240SCA Is Used
Robot gripper tilt
Tilting a welding robot's fixture clamp through a linkage, the CA pivot absorbing the swing without a custom bracket.
Sluice gate actuator
Raising a small water-treatment sluice gate through a lever arm, with the stainless barrel standing up to the wet environment.
Press discharge flap
Swinging a stamping press's discharge flap 240 mm clear, with a CMSG switch confirming the flap is fully open before parts exit.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X240SCA the Right Cylinder?
Below 900 N of working force at 0.5 MPa, compare the 40 mm bore (628.3 N push); above it, the 63 mm bore offers 1557.9 N. The CA cover handles pivoting mounts on its own, while FA, LB or SDB brackets cover fixed installations. Thread here is PT on 1/4 in ports; G and NPT are options. A 240 mm stroke in a swing linkage can see bending loads at the rod - keep the mechanism aligned and support external side forces. The cushion slows the piston but does not hold it: when supply air drops, the rod drifts, so add a pilot check valve or rod lock wherever a raised linkage must stay put.
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 MAC50X240SCA FAQ
At 0.5 MPa: 981.3 N push and 880.8 N pull. At 0.7 MPa: 1373.8 N push and 1233.1 N pull. Theoretical maximum 200.1 kgf at 1.0 MPa. Bore 50 mm, rod 16 mm with M14x1.5 thread, 1/4 in ports, PT thread, 240 mm stroke, double acting with variable air cushions and speed range 30-800 mm/s.
Yes - the CA pivot end is designed for linkages and swing mechanisms, letting the cylinder rotate about its rear pin. If the machine needs a fixed mount instead, order the U flat-end or CM round-end cover, or keep CA and add an FA flange, LB foot or SDB pivot bracket. The built-in piston magnet works with CMSG, DMSG and EMSG switches in any of these arrangements.
