Airtac MAC Stainless Steel Mini Air Cylinder MAC50X550SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X550SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 550mm 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 MAC50X550SU
Flat-ended and plain-facing, the U back cover on this model presents a clean fixed face for flange or foot mounting without a pivot. Double-acting air drives the rod both ways, up to 981 N push at 0.5 MPa (72 psi), and needle screws set the variable cushion at each end. Because 550 mm sits above the 500 mm standard, the barrel is made to order.
The rolled stainless shell and 20 um chrome-plated rod stay tight and clean under vibration, handy on shaking machines such as sifters and vibratory feeders. Size tooling around 589 N of working thrust at 0.5 MPa rather than the full 981 N, and the piston magnet pairs with CMSG, DMSG or EMSG switches straight from the carton.

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 MAC50X550SU Is Used
Flour sifter tray
Drives a shaker tray on a flour sifter where the rolled barrel rides out constant vibration and 1374 N at 0.7 MPa (102 psi) clears a jammed screen.
Kiln-car stopper
Pops a stop up to catch kiln cars at the loader; the cushion bleeds off the impact of a loaded car instead of hammering the cover.
Washdown tote lift
Lifts totes between washdown conveyor levels; the stainless barrel and chromed rod take the daily hose-down while moving about 50 kg with margin.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X550SU the Right Cylinder?
Step down to a 40 mm bore for 628 N at 0.5 MPa (72 psi) or up to 63 mm for 1558 N if this 50 mm size overshoots or undershoots. The rod is uncontrolled once air is dumped, so a rod lock or pilot check valve is the fix for suspended loads. FA flange and LB foot mounts bolt straight to the flat U cover; across 550 mm of travel, guide the load externally so the 16 mm rod sees no side thrust.
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 MAC50X550SU FAQ
At 0.5 MPa: 981 N push and 881 N pull; at 0.7 MPa: 1374 N push; 200.1 kgf theoretical maximum at 1.0 MPa. Operating band 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s.
The barrel resists corrosion from washdown, humidity and outdoor exposure without paint to chip or flake, and the 20 um hard-chrome rod keeps seals wiping clean even in abrasive or wet air.
