Airtac MAC Stainless Steel Mini Air Cylinder MAC50X150SCAH
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X150SCAH 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 MAC50X150SCAH
A 50 mm bore in AirTAC's round stainless MA family, the MAC50X150SCAH is double acting with a variable air cushion at each end and a 150 mm stroke. At 0.5 MPa (73 psi) it develops 981.3 N on extension and 880.8 N on retraction through a 16 mm hard-chrome plated rod, climbing to 1373.8 N at 0.7 MPa (102 psi).
The riveted stainless barrel shrugs off washdown and humid plant air that eats painted-steel minis, while the CA pivot back cover takes a pivoting mount without extra brackets. The built-in magnet is standard, so CMSG, DMSG or EMSG switches clip straight on. In practice, budget roughly 589 N of the rated push for real work at 0.5 MPa - the rest covers friction, side load and wear.

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 MAC50X150SCAH Is Used
Stamping die change lift
The CA pivot back cover swings on a linkage to hoist a 40-50 kg die shoe out of a press bolster, staying inside the roughly 50 kg vertical capacity this bore offers with a 2:1 margin.
Pallet stop actuator
Pivoting a pop-up stop on a bottling conveyor, where 981 N of push holds back loaded pallets and the air cushion kills the slam.
Washdown gate drive
Swinging a divert gate on a washed-down food line; the stainless barrel and 1/4" ports survive daily hose-down that corrodes painted minis.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X150SCAH the Right Cylinder?
Right-size against the family: the 40 mm MAC40 pushes 628.3 N at 0.5 MPa (73 psi) and the 63 mm MAC63 reaches 1557.9 N, so the 50 mm bore sits squarely between them for mid-weight tooling. Cut the air and this piston coasts freely - the cushions only soften the last millimetres, so spec a rod lock or pilot check valve wherever the rod must stay put. FA flange, LB foot and SDB pivot brackets handle body mounting; the CA pivot back cover on this model pairs naturally with linkages and swing arms over the 150 mm travel.
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 MAC50X150SCAH FAQ
At 0.5 MPa (73 psi) it pushes 981.3 N and pulls 880.8 N; at 0.7 MPa (102 psi) push rises to 1373.8 N. Theoretical maximum is 200.1 kgf at 1.0 MPa. Working range is 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, ports 1/4", rod thread M14x1.5.
Both ends carry a variable cushion. Open the needle screws fully before the first stroke, run the cylinder, then close them gradually until the end-of-stroke impact is gone. Do not screw them fully shut - the cushion is a shock damper, not a brake or position lock.
