Airtac MAC Stainless Steel Mini Air Cylinder MAC50X70SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X70SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 70mm 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 MAC50X70SCA
Standard 70 mm stroke, CA pivot back cover, 50 mm bore: this MAC round-body mini cylinder pushes 981.3 N and pulls 880.8 N at 0.5 MPa, climbing to 1373.8 N of extension force at 0.7 MPa against a 200.1 kgf theoretical peak. Air drives the rod both ways - it is double acting - and a variable air cushion at each end tames end-of-stroke shock on fast cycles.
Build quality is the story: a stainless round barrel rolled tight against aluminium-alloy covers, with a 16 mm hard-chrome steel rod that tolerates washdown and humid air where painted minis peel. On vertical work, halve the theoretical 100 kg lift figure for a 2:1 margin and you still move about 50 kg cleanly. The built-in magnet accepts CMSG, DMSG and EMSG switches out of the box.

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 MAC50X70SCA Is Used
Clamp on a handrail welding jig
981.3 N at 0.5 MPa holds tube joints square through the weld cycle; the 70 mm stroke suits compact fixture spacing.
Carton stop at a distribution pick station
The 70 mm stroke raises or drops a stop blade just in time, and CMSG switches on the standard magnet confirm end position.
Lid press on a pail filling line
About 589 N of working press force seats snap-on lids cleanly, cushioned at both ends so there is no slam on the pail rim.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X70SCA the Right Cylinder?
Weigh it against the 40 mm bore (628.3 N push at 0.5 MPa) and the 63 mm bore (1557.9 N) to land on the right size first time. Air supply spans 0.15-1.0 MPa (22-145 psi), and the cylinder does not park the load: centre the valve or drop the air and the rod will move, so a rod lock or pilot check valve is the answer for held positions. The CA pivot cover swings on a clevis pin without adapters, while FA flange, LB foot and SDB pivot brackets cover fixed mounting; the standard magnet pairs with CMSG, DMSG and 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 MAC50X70SCA 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; theoretical maximum 200.1 kgf at 1.0 MPa. Double acting with a two-end variable cushion, 0.15-1.0 MPa (22-145 psi) supply, 30-800 mm/s speed, 1/4 inch port, M14x1.5 rod thread.
No. Every MAC cylinder carries a piston magnet as standard equipment, so CMSG, DMSG and EMSG switches mount straight onto the barrel. The stainless round body also shrugs off the washdown that rusts painted mini cylinders in food and packaging areas.
