Airtac MAC Stainless Steel Mini Air Cylinder MAC50X300SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X300SCM 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 MAC50X300SCM
At 300 mm of stroke and 50 mm of bore, this MAC pushes 981 N at 0.5 MPa - roughly a 100 kg dead lift - while staying a slim round-body mini. Double acting by design, it uses a variable air cushion at both ends, so long fast strokes can be tuned to land quietly instead of banging the covers.
The CM round-end back cover keeps the tail clean for clevis or pin-type pivots in custom fixtures. Build quality is where the MAC earns its keep: a stainless barrel, a 20 um hard-chrome rod and grease-retaining piston seals survive damp, dusty and washdown air that corrodes painted minis. The magnet is standard too, so CMSG/DMSG/EMSG switches drop on. Practical sizing: count on 589 N of usable push at 0.5 MPa, or about 50 kg of vertical lift with a 2:1 margin.

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 MAC50X300SCM Is Used
Dock cart pusher
Shunts wheeled trolleys along a loading-dock rail; 981 N overcomes the start-up friction of a 400 kg cart train.
Lab sample elevator
Lifts sample racks 300 mm between inspection stations in a humid analytical lab, where the stainless body beats painted steel.
Thermoform ejector assist
Helps eject large plastic lids from a thermoform tool, with the cushion adjusted so parts drop without bounce.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X300SCM the Right Cylinder?
Compare before you commit: a MAC32 gives 402 N push at 0.5 MPa and a MAC63 delivers 1558 N - this 50 mm sits squarely in the 100 kgf class. Remember the rod is not locked: when air is removed the piston drifts, so a rod lock or pilot check valve is essential for held positions. Over 300 mm, even small side loads bend the 16 mm rod, so guide the load externally or fit an I or Y rod knuckle. FA flange, LB foot or SDB pivot brackets cover fixed mounting, and the piston magnet is already in place for sensing.
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 MAC50X300SCM FAQ
Yes. Push force is 981 N at 0.5 MPa and 1374 N at 0.7 MPa (pull: 881 N and 1233 N); the theoretical maximum is about 200 kgf at 1.0 MPa. That supports a 100 kg vertical lift at full pressure - use about 50 kg for a 2:1 margin. Speed 30-800 mm/s, pressure 0.15-1.0 MPa (22-145 psi).
Back both needle screws fully out on first run-up, then close them gradually until end-of-stroke impact disappears. The cushions are variable at both ends, which is why the MAC can run strokes at up to 800 mm/s without damaging the covers.
