Airtac MAC Stainless Steel Mini Air Cylinder MAC50X280SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X280SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 280mm 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 MAC50X280SCA
Where a straight fixed mount will not reach, the MAC50X280SCA hangs from its CA pivot back cover and follows the motion. Inside is a 50 mm double-acting piston delivering 981.3 N at 0.5 MPa and 1373.8 N at 0.7 MPa through a 280 mm stroke, slowed gently at both ends by the variable air cushion. The riveted stainless round barrel shrugs off the mild corrosion that kills painted mini cylinders in washdown or coastal sites.
Hang a load on the rod and it will hoist roughly 100 kg vertically; work at about half that, near 50 kg, for a solid 2:1 margin. Day-to-day loads near 589 N - six tenths of the 0.5 MPa rating - keep the internals comfortable. The magnet is factory fitted, so CMSG / DMSG / EMSG switches mount in seconds. 1/4" ports, M14x1.5 rod thread, 30-800 mm/s speed, 0.15-1.0 MPa (22-145 psi) supply, 1.5 MPa (215 psi) proof.

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 MAC50X280SCA Is Used
Mast-mounted load pusher
Fitted to forklift attachments and order pickers, the 280 mm stroke nudges pallets square with 981.3 N of push at 0.5 MPa.
Rotary table trigger linkage
The pivot cover drives a bell-crank that indexes a machining rotary table, cushioned so the indexer never slams its detent.
Roller-gate lowering
A pivot-mounted gate section on a bottling line drops through 280 mm to release bottles, lifting about 50 kg with a 2:1 margin.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X280SCA the Right Cylinder?
Between bores, a 40 mm unit saves space with 628.3 N at 0.5 MPa while a 63 mm adds 1557.9 N for the toughest pushes - the 50 mm is the balanced middle. Remember the rod is free the moment air is removed: a pilot check valve or rod lock is the answer for suspended loads, not the cushion, which only softens end travel. Add an SDB pivot bracket at the rod end or FA flange / LB foot mounts where the frame demands them, plus I or Y knuckles.
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 MAC50X280SCA FAQ
At 0.5 MPa: 981.3 N push, 880.8 N pull. At 0.7 MPa: 1373.8 N push, 1233.1 N pull. Maximum theoretical force is 200.1 kgf at 1.0 MPa. Pressure span 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi).
Back both needle screws fully out before start-up, then close them gradually until end-of-stroke impact disappears. The MAC runs 30-800 mm/s, and its riveted stainless body with hard-chrome 16 mm rod plus standard magnet for CMSG / DMSG / EMSG switches stays as specified.
