Airtac MAC Stainless Steel Mini Air Cylinder MAC50X300SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X300SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 300mm 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 MAC50X300SCA
Need a 300 mm working stroke with serious muscle? The MAC50X300SCA pairs AirTAC's 50 mm cushioned mini bore with a CA pivot back cover, producing 981 N of push at 0.5 MPa and 1374 N at 0.7 MPa - around 100 kgf from a body slim enough for tight machine frames.
Air extends and retracts the rod (double acting), and needle-screw air cushions at each end absorb arrival energy so you can run long strokes faster without hammering the covers. Inside, a hard-chrome plated 16 mm rod slides in a stainless barrel riveted into one sealed round body that stays tight under vibration. Sized honestly, that is about 589 N of usable push at 0.5 MPa, or a vertical lift of roughly 100 kg - call it 50 kg with a 2:1 safety factor.

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 MAC50X300SCA Is Used
Pallet stop and release
Stops and releases pallets at a robotic pick cell, cycling the full 300 mm stroke every few seconds at up to 800 mm/s.
Clamp-and-clear fixture
Clamps a welded bracket then retracts clear for loading on a fabrication cell rotary table, cushioned so parts stay put.
Oven door ram
Drives the sliding door of a powder-curing oven; the stainless round body stands up to heat-zone humidity better than painted steel.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X300SCA the Right Cylinder?
A MAC40 cylinder tops out at 628 N push at 0.5 MPa; if your load needs more than about 60 kgf of breakaway force, this 50 mm bore is the right call, and a MAC63 (1558 N) covers heavier duty. Because a plain MAC drifts when the valve centres or air drops, add a pilot check valve or rod lock wherever the rod must stay put. The CA pivot back cover mounts directly on swinging links and levers, FA flange, LB foot or SDB pivot brackets suit fixed frames, and the standard magnet drives CMSG/DMSG/EMSG switches. On 300 mm strokes, keep side load away from the rod with external guiding or a knuckle joint.
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 MAC50X300SCA FAQ
Push at 0.5 MPa is 981 N and pull 881 N; at 0.7 MPa those become 1374 N and 1233 N. At the 1.0 MPa limit the theoretical maximum is about 200 kgf. Air supply is 0.15-1.0 MPa (22-145 psi) and speed range 30-800 mm/s.
The CA option turns the back cover into a pivot eye, so the cylinder swings with levers or linkages without an extra bracket. Either way you keep the double-acting drive, the variable air cushion at both ends and the built-in magnet for CMSG/DMSG/EMSG switches.
