Airtac MAC Stainless Steel Mini Air Cylinder MAC50X150SCMH
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X150SCMH is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 150mm 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 MAC50X150SCMH
For wet, washed or outdoor stations, few 50 mm minis hold up like this one: the MAC50X150SCMH keeps a stainless barrel and hard-chrome plated rod working long after painted bodies have rusted through. It is double acting over a 150 mm stroke, pushing 981.3 N and pulling 880.8 N at 0.5 MPa (73 psi).
Both ends carry a variable air cushion, so end-of-stroke shock is tuned down by the needle screws rather than absorbed by your machine frame. The CM round-end back cover bolts to fixed or pivoted hardware without an adapter, and the built-in magnet ships standard for CMSG / DMSG / EMSG switches. For sizing, treat about 589 N - six tenths of the rated push - as the force you can actually put to work at 0.5 MPa.

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 MAC50X150SCMH Is Used
Weldment gripper clamp
Squeezing a rod weldment in a fabrication cell jig, where about 589 N of dependable clamping force keeps the joint seated through tack welding.
Diverter flap actuator
Turning a heavy diverter flap on a grain handling spout, cushioned so the flap lands quietly at each end of the 150 mm arc.
Cold-store takeaway push
Nudging cartons onto a freezer-room takeaway conveyor, where -20 C ratings and the stainless body handle frost and damp air.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X150SCMH the Right Cylinder?
Cross-check sizing: drop to the 40 mm bore for lighter clamping (628.3 N push at 0.5 MPa (73 psi)) or climb to the 63 mm bore (1557.9 N) when presses demand more. A plain MAC never locks mid-stroke - lose supply and the load walks the rod, so pair it with a rod lock or check valve where positions must hold. Foot (LB), flange (FA) and pivot (SDB) brackets all suit the round barrel, and the piston magnet is ready for CMSG, DMSG or EMSG switches. Guide the 150 mm stroke externally; the 16 mm rod tolerates little 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 MAC50X150SCMH FAQ
Figures for this 50 mm bore: push 981.3 N and pull 880.8 N at 0.5 MPa (73 psi), push 1373.8 N at 0.7 MPa (102 psi), theoretical maximum 200.1 kgf at 1.0 MPa. Rated pressure span 0.15-1.0 MPa (22-145 psi); speed 30-800 mm/s.
No. Every MAC50X150SCMH ships with the magnet already built in, so CMSG, DMSG and EMSG switches clamp straight onto the barrel. The sensor magnet is standard across the whole MA family, not a paid option.
