Airtac MAC Stainless Steel Mini Air Cylinder MAC50X270SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X270SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 270mm 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 MAC50X270SCM
Needing 270 mm of travel without stepping up to a big-bore body, the MAC50X270SCM pairs a 50 mm bore with a riveted stainless-steel barrel. Double acting with a variable air cushion at both ends, it pushes 981.3 N at 0.5 MPa and 1373.8 N at 0.7 MPa. The CM round-end back cover bolts flat against a fixture with no adapter plate, and the hard-chrome 16 mm rod stands up to washdown and outdoor damp that swell painted minis.
In practice, plan workloads around 589 N - about 60% of the 0.5 MPa push figure - so seals and tooling run with margin. Mounted upright it raises roughly 100 kg against gravity, or about 50 kg with a 2:1 safety margin on real part weights. The piston magnet ships as standard, so a CMSG, DMSG or EMSG switch clips straight on. Ports are 1/4", rod thread M14x1.5, speed range 30-800 mm/s, working pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi).

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 MAC50X270SCM Is Used
Baler platen drive
The 981.3 N push at 0.5 MPa shoves scrap or offcuts along a 270 mm compaction channel, with the air cushion absorbing platen impact.
Guard gate lifting
Rigged vertically it raises about 50 kg of machine guarding with a 2:1 margin, cushioning softly at the top of travel.
Carton push-off on palletisers
A 270 mm stroke sweeps boxes sideways off a conveyor lane; the CMSG switch (magnet standard) confirms the parked position.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X270SCM the Right Cylinder?
Size down to a 40 mm bore (628.3 N push at 0.5 MPa) when the load is lighter and speed matters more, or up to 63 mm (1557.9 N) for heavy pressing. Keep in mind the MAC does not lock its position when air drops - the piston simply drifts - so fit a rod lock or pilot check valve where a load must stay put. If the CM round-end cover does not suit the frame, CA pivot and U flat-end covers swap in, with FA flange, LB foot or SDB pivot brackets and I/Y knuckles available.
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 MAC50X270SCM FAQ
At 0.5 MPa it pushes 981.3 N and pulls 880.8 N; at 0.7 MPa those rise to 1373.8 N and 1233.1 N. Theoretical maximum is 200.1 kgf at 1.0 MPa. Working pressure runs 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof.
It gives a flat, round mounting face that bolts directly to plates and machine frames, so no extra bracket is needed. The body stays a riveted stainless round barrel with a hard-chrome 16 mm rod, and the built-in magnet still accepts CMSG / DMSG / EMSG switches.
