Airtac MAC Stainless Steel Mini Air Cylinder MAC50X500SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X500SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 500mm 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 MAC50X500SCA
Five hundred millimetres is the longest standard stroke the bore 50 MAC family offers, and this CA pivot version brings 981.3 N of push and 880.8 N of pull at 0.5 MPa to that full travel. The rolling-packed body - stainless barrel, hard-chrome rod, riveted aluminium covers - stays sealed against dust and splash with no through-fasteners to service.
Both ends carry a variable air cushion, so a fast 500 mm move can be braked quietly even with a heavy gate on the rod; crack the needle screws open at commissioning and tune them in. For continuous duty budget roughly 589 N of push at 0.5 MPa - six tenths of the rating - and let external guides take the sideways loads. The piston magnet is factory standard, so CMSG / DMSG / EMSG switches report both end positions without ordering anything special.

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 MAC50X500SCA Is Used
Sorter merge gate
Swinging a long merge gate across a parcel-sorter lane - 500 mm of pivot throw and 981 N at 0.5 MPa moves loaded cartons cleanly past the divert.
Kiln-car latch
Pulling open a heavy latch arm on a brick kiln car, where stainless and hard chrome outlast painted minis in hot, gritty air and the cushion eases the arm home.
Grain-chute deflector
Dropping a deflector plate into a grain-auger stream; the CA pivot tracks the plate's arc and the full 500 mm stroke reaches the bottom of a deep chute.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X500SCA the Right Cylinder?
Bracket the choice by force: a 40 mm MAC produces 628.3 N push at 0.5 MPa and the 63 mm version 1557.9 N, so a duty landing between about 600 and 1000 N of working force belongs at bore 50. The CA eye on the back cover lets the whole body pivot with the load path; FA flange, LB foot and SDB brackets plus I / Y rod knuckles handle the remaining mounts. Across half a metre of travel, side load is the main killer - run the gate on its own rails or the 16 mm rod will wear and whip. Centring the valve vents both ports and leaves the rod free to be driven back, so a rod lock or pilot check valve is what actually holds a suspended position.
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 MAC50X500SCA FAQ
At 0.5 MPa: 981.3 N on the push stroke, 880.8 N on the pull stroke. At 0.7 MPa: 1373.8 N push and 1233.1 N pull. The theoretical ceiling at 1.0 MPa is 200.1 kgf. Operating range 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, air filtered to 40 um, 1/4 in ports.
The stainless tube shrugs off washdown chemicals and outdoor weather, and the 20 um hard-chrome rod resists scoring and rust, so the cylinder keeps sliding where painted-steel or bare-aluminium minis pit and drag. The riveted body leaves no exposed fasteners to work loose under vibration, and the two-way piston seal holds its own grease film.
