Airtac MAC Stainless Steel Mini Air Cylinder MAC50X450SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X450SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 450mm 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 MAC50X450SCM
The CM round-end back cover on this MAC50X450SCM gives a compact, finished nose for fixed installations without pivots, while the 50 mm bore drives 450 mm of stroke with about 981 N of push at 0.5 MPa. Double acting and cushioned at both ends, it runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi).
Riveted stainless barrel, 20 um hard-chromed carbon-steel rod and aluminium covers form a sealed round body that shrugs off splash and mild corrosives in food and marine settings. Set the needle screws fully open at commissioning, then close them gradually until end-of-stroke knock disappears - the variable cushion lets you move heavier loads faster without cover damage. For sizing, treat about 589 N at 0.5 MPa as usable force, which matches a roughly 50 kg vertical lift at a 2:1 margin. The standard magnet accepts CMSG / DMSG / EMSG switches with nothing extra to order.

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 MAC50X450SCM Is Used
Spray-booth door drive
Sliding a paint-booth door along its track, the cylinder pulls 1233 N at 0.7 MPa and the 450 mm stroke covers full door travel.
Penstock valve on a water-treatment skid
Wet, splashy surroundings suit the stainless build; about 100 kg of vertical-lift force raises a small gate without gears.
End-of-line case squaring
Before strapping, the pusher squares slumped cartons; 981 N at 0.5 MPa does the job and the air cushion makes the contact gentle.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X450SCM the Right Cylinder?
If 981 N at 0.5 MPa is more than the job needs, MAC40X delivers about 628 N; if the load outgrows it, MAC63X reaches 1558 N. The CM end suits direct bolting, while CA pivot or U flat-end versions cover swinging and face-mounted frames, and FA flange or LB foot parts adapt to any frame. Port thread is 1/4 inch PT as standard, with G and NPT (T) available. A 450 mm stroke deserves external guiding, as a 16 mm rod will bend under side loads. Remember a plain MAC holds nothing when air drops - the piston coasts - so fit a rod lock or pilot check valve wherever a load must stay raised.
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 MAC50X450SCM FAQ
Push is 981 N and pull 881 N at 0.5 MPa, rising to 1374 N and 1233 N at 0.7 MPa, with a 200 kgf theoretical ceiling at 1.0 MPa. Ports are 1/4 inch, the rod is 16 mm with M14x1.5 male thread, and 450 mm stays within the 500 mm standard stroke.
Its barrel is stainless steel and the 16 mm rod carries a 20 um hard-chrome plating, so splash, humidity and mild corrosives are handled far better than painted mini cylinders manage. The riveted, rolled construction seals the barrel between aluminium covers, making the design a fit for washdown zones, marine decks and open-air machinery. Avoid constant salt immersion or aggressive chemicals.
