Airtac MAC Stainless Steel Mini Air Cylinder MAC50X550SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X550SCM 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 MAC50X550SCM
A round-end CM back cover gives this 50 mm double-acting cylinder a pivoting attachment built into the cover itself, so swing links connect without extra brackets. Push force reaches 981 N at 0.5 MPa (72 psi), and the variable cushion at each end trims the landing of heavy loads. The 550 mm stroke is custom-rolled because the standard ceiling here is 500 mm.
The stainless tube and hard-chrome plated rod shrug off splashes and mild corrosion, an edge over painted minis in outdoor gates and food plants. Vertically, 981 N equates to about 100 kg - halve that for a margin and the cylinder lifts roughly 50 kg on a hoist-assist arm with room to spare.

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 MAC50X550SCM Is Used
Hopper slide gate
Opens and closes a slide gate under a grain hopper; the round-end cover pivots the link naturally and 881 N of pull retracts the gate against grain load.
Case-packer ejector
Kicks cartons sideways on a case packer; the 550 mm custom stroke crosses the full conveyor and the stainless body survives syrupy spill zones.
Jib-assist tray lift
Raises about 50 kg fixture trays on a machining jib; a DMSG switch snaps onto the standard magnet so the PLC knows top and bottom dead centre.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X550SCM the Right Cylinder?
Compare bores on 0.5 MPa (72 psi) push: 40 mm yields 628 N and 63 mm yields 1558 N, placing this 50 mm size in between at 981 N. Once the valve centres, the rod is free to move - fit a pilot check valve or rod lock where a held position matters. The CM round end suits swing links; LB foot or FA flange mounts handle fixed frames, and the 16 mm rod should stay square to its load across 550 mm of travel.
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 MAC50X550SCM FAQ
Push is 981 N and pull 881 N at 0.5 MPa; at 0.7 MPa push reaches 1374 N; theoretical maximum is 200.1 kgf at 1.0 MPa. Air supply 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, 1/4" port, rod thread M14x1.5.
No. The magnet is built into the piston as standard across the MAC series, so CMSG, DMSG or EMSG reed switches simply clip into the barrel groove for end-of-stroke or mid-stroke signalling.
